Introduction
Introduction
Suppose your company wants to sell products online. You have a database that gives
the price and inventory status of each item. However, your database doesn’t speak
HTTP, the protocol that Web browsers use. Nor does it output HTML, the format
Web browsers need. What can you do? Once users know what they want to buy, how
do you gather that information? You want to customize your site for visitors’ prefer-
ences and interests, but how? You want to keep track of user’s purchases as they shop
at your site, but what techniques are required to implement this behavior? When
your Web site becomes popular, you might want to compress pages to reduce band-
width. How can you do this without causing your site to fail for those visitors whose
browsers don’t support compression? In all these cases, you need a program to act as
the intermediary between the browser and some server-side resource. This book is
about using the Java platform for this type of program.
“Wait a second,” you say. “Didn’t you already write a book about that?” Well, yes.
In May of 2000, Sun Microsystems Press and Prentice Hall released Marty Hall’s sec-
ond book, Core Servlets and JavaServer Pages. It was successful beyond everyone’s
wildest expectations, selling approximately 100,000 copies, getting translated into
Bulgarian, Chinese simplified script, Chinese traditional script, Czech, French, Ger-
man, Hebrew, Japanese, Korean, Polish, Russian, and Spanish, and being chosen by
Amazon.com as one of the top five computer programming books of 2001. What fun!
Since then, use of servlets and JSP has continued to grow at a phenomenal
rate. The Java 2 Platform has become the technology of choice for developing
e-commerce applications, dynamic Web sites, and Web-enabled applications and
service. Servlets and JSP continue to be the foundation of this platform—they pro-
vide the link between Web clients and server-side applications. Virtually all major

Introduction
xviii
Web servers for Windows, UNIX (including Linux), Mac OS, VMS, and mainframe
operating systems now support servlet and JSP technology either natively or by
means of a plug-in. With only a small amount of configuration, you can run servlets
and JSP in Microsoft IIS, the Apache Web Server, IBM WebSphere, BEA
WebLogic, Oracle Application Server 10g, and dozens of other servers. Perfor-
mance of both commercial and open-source servlet and JSP engines has improved
significantly.
To no one’s surprise, this field continues to grow at a rapid rate. As a result, we
could no longer cover the technology in a single book. Core Servlets and JavaServer
Pages, Volume 1: Core Technologies, covers the servlet and JSP capabilities that you
are likely to use in almost every real-life project. This book, Volume 2: Advanced
Technologies, covers features that you may use less frequently but are extremely valu-
able in robust applications. For example,
• Deployment descriptor file. Through the proper use of the
deployment descriptor file, web.xml, you can control many aspects of
the Web application behavior, from preloading servlets, to restricting
resource access, to controlling session time-outs.
• Web application security. In any Web application today, security is a
must! The servlet and JSP security model allows you to easily create
login pages and control access to resources.
• Custom tag libraries. Custom tags significantly improve the design
of JSPs. Custom tags allow you to easily develop your own library of
reusable tags specific to your business applications. In addition to
creating your own tags, we cover the Standard Tag Library (JSTL).
• Event handling. With the events framework, you can control
initialization and shutdown of the Web application, recognize
destruction of HTTP sessions, and set application-wide values.
• Servlet and JSP filters. With filters, you can apply many pre- and
post-processing actions. For instance, logging incoming requests,
blocking access, and modifying the servlet or JSP response.
• Apache Struts. This framework greatly enhances the standard
model-view-controller (MVC) architecture available with servlets and
JSPs. More importantly, Apache Struts still remains one of the most
common frameworks used in industry.
Who Should Read This Book
The main audience is developers who are familiar with basic servlet and JSP technol-
ogies, but want to make use of advanced capabilities. As we cover many topics in this
book—the deployment descriptor file, security, listeners, custom tags, JSTL, Struts,

Introduction xix
Ant—you may want to first start with the technologies of most interest, and then later
read the remaining material. Most commercial servlet and JSP Web applications take
advantage of the technologies presented throughout, thus, at some point you may
want to read the complete book.
If you are new to servlets and JSPs, you will want to read Core Servlets and Java-
Server Pages, Volume 1: Core Technologies. In addition to teaching you how to install
and configure a servlet container, Volume 1 provides excellent coverage of the servlet
and JSP specifications. Volume 1 provides the foundation material to this book.
Both books assume that you are familiar with basic Java programming. You don’t
have to be an expert Java developer, but if you know nothing about the Java program-
ming language, this is not the place to start. After all, servlet and JSP technology is an
application of the Java programming language. If you don’t know the language, you
can’t apply it. So, if you know nothing about basic Java development, start with a
good introductory book like Thinking in Java, Core Java, or Core Web Programming,
all from Prentice Hall.
Conventions
Throughout the book, concrete programming constructs or program output are pre-
sented in a monospaced font. For example, when abstractly discussing server-side
programs that use HTTP, we might refer to “HTTP servlets” or just “servlets,” but
when we say HttpServlet we are talking about a specific Java class.
User input is indicated in boldface, and command-line prompts are either generic
(Prompt>) or indicate the operating system to which they apply (DOS>). For
instance, the following indicates that “Some Output” is the result when “java
SomeProgram” is executed on any platform.
Prompt> java SomeProgram
Some Output
URLs, file names, and directory names are presented in a sans serif font. So, for
example, we would say “the StringTokenizer class” (monospaced because we’re
talking about the class name) and “Listing such and such shows SomeFile.java” (sans-
serif because we’re talking about the file name). Paths use forward slashes as in
URLs unless they are specific to the Windows operating system. So, for instance, we
would use a forward slash when saying “look in install_dir/bin” (OS neutral), but use
backslashes when saying “see C:WindowsTemp” (Windows specific).
Important standard techniques are indicated by specially marked entries, as in the
following example.

I got a firmer grip on Perry's collar.
"Come and get me," I called back, knowing what would happen if
they did.
They came in on the double with their freeze guns ready—and
halted, looking sheepish, when the smiley's aura got to them.
"Aw, forget it," the corporal said. "You're a good guy, Bailey. Go
ahead. Go anywhere you like."
"Sure," the other seconded. "Take our air-scooter if you want. Need
any extra credits where you're going?"
I headed for the service with Perry again but we had waited too
long. One of Shanig's uglies was standing in the doorway with a
foolish grin on his face, and I knew there would be others waiting in
the alley outside. And those others wouldn't be under Joey's
influence.
So I cut for the front entrance instead, dragging Perry like a bag of
old laundry. The patrolies' air-scooter stood purring at the curb. I
draped Perry across it and jumped for the operator's seat, expecting
to be beamed down any second. I'd have made it, too, but for Perry.
Perry had taken on a monumental load of skohl during the day, and
the instant he was out of Joey's influence the inflated little ego of
him demanded to be heard. He scrambled off the air-scooter, swelled
out his size thirty-two chest and launched into an old rocketroom
ballad—a smutty saga listing the personal iniquities of the Captain
Crow who led the first Mars flight just before the turn of the century.
In nineteen hundred and ninety-two
A homo from Milwaukee
Warmed up his jets and—
I quieted him with a rabbit punch and tossed him back on the air-
scooter, but the damage was done. I hit the control seat again just
as Shanig's crew swarmed out of the alley and surrounded us.

The air-scooter took off like a rocket when I gave it the gun, plowing
straight through them. I hung on somehow, but Perry wasn't so
lucky. He bounced once and pitched off, square into the enemy's
hands.
When I looked back at the first street intersection they had scooped
him up and were headed toward Solar Shipping in a hurry. The sight
reassured me a little. They hadn't blasted Perry on the spot, which
meant that they would probably hold him as hostage until they got
Cheryl as well. One witness at large was as dangerous to Shanig as
two, and the chances were he wouldn't risk beaming out one unless
he could be sure of both.
I took the only course left, doubling the air-scooter back and
skimming toward Shanig's offices.
V
The way the situation added up reminded me of the old historical
thrillers I'd read as a kid, most of them written in the days when our
rough-and-ready ancestors bought contraband skohl from
underground talk-gentlies and rival groups of uglies hijinked each
other with torpedoes. It was something like a present-day telemovie
gripper in a sense, only there wasn't any Colonel Super in this plot to
lend me a hand.
Not that I wasted time looking for help. I wasn't used to it.
Outside the Solar Shipping building I lifted the air-scooter and
swooped up to the balcony outside Shanig's office windows. There
wasn't time to set it down. I needed every second to get inside
before Shanig could give the alarm.

I jumped, and the air-scooter went on without me into the night. It
wouldn't have worked on Earth, but under Mars' .38 gravity an
athletic homo has all the breaks. I landed just inside the guard-rail
and dived through the balcony windows with a great crashing of
glass before Shanig could clap a hand to the buzzer on his desk.
"Don't touch it," I said, and turned my Quantrell on him.
"You!" Shanig barked. His face went sallower than ever, but his hot
black eyes didn't waver. "What do you want here?"
Down the corridor rose a sudden babel of voices—Shanig's crew
returning with their prize.

"They got Acree," I said, heading for the phonovision unit beside
Shanig's desk. "But if you make a sound before they get here you
won't be able to use him. Clear?"
The screen lit up when I touched the switch. I punched the code
Cheryl had given me, and drew the first deep breath I'd had for an
hour when she looked out at me.
"Bring Cora over to Shanig's office on the double," I said. "I'm going
to need her but quick!"
I cut her off without waiting for an answer and punched another
number. Captain Giles stared out at me this time, his weathered
hatched face clownish with astonishment.
"Get a crew of patrolies up to Shanig's offices," I said. "And make it
fast or there's going to be more excitement here than you can write
off your records in a month."
For the first time Shanig looked worried. He saw no threat in Cheryl's
coming, not knowing about my second smiley. But if Captain Giles
should arrive before Perry could be moved—
The crew of uglies outside crossed me up by buzzing Shanig's
audiphone. "We got the little homo, Chief. Shall we bring him in?"
Shanig, knowing that I couldn't afford to beam him at this stage of
the game, tipped them before I could stop him. "Take him away.
Bailey's here!"
I jumped for the door, hoping to grab Perry before they got him
away. I was too late. They were already out of the reception office.
All I saw of Perry Acree was his heels.
That left us at stalemate. Shanig couldn't get away, and I couldn't
leave him unguarded to go after Perry. I was racking my brain for
the next move when it was taken out of my hands.
The phonovision screen beside Shanig's desk lighted up and one of
his uglies looked out. "We got him where he won't be found, Chief.
What next?"

And I let Shanig beat me to the jump again. "The girl is coming
here. Intercept her!"
I made sure it wouldn't happen again by raying the phonovision unit
to a heap of smoking junk. Reflected heat from the flash curled
Shanig's eyebrows, but he didn't flinch.
"That finishes you, Bailey," he said. "My men have Acree safe. They'll
have the girl the instant she appears. Under the circumstances it
should be quite entertaining to watch you prove your position to the
police."
He had me cold. Shanig could afford to wait but I couldn't.
It turned out that Shanig's handymen didn't share his confidence in
the police. I heard them getting set in the reception-room corridor to
block any dash I might make. When I sneaked a look through the
balcony windows I caught a glimpse of another group working like
beavers in the building across the alley. They were setting up a
tripod affair which I recognized at a glance as a sleep-bomb
catapult.
They had it charged to fire when Captain Giles and his patrolies
arrived. A babble of confusion rose in the corridor again, and the
Captain's harsh bellow silenced it like a hand across the mouth. A
moment later he called through the doorway: "Stand fast, Bailey.
We're coming in, and God help you if you give us trouble!"
I stood fast, giving up any hope of Cheryl's showing up in time.
Having Cora along should make it easy enough for her to get into
the building, but even Cora couldn't help if Captain Giles had already
dragged me away.
Giles came around Shanig's desk toward me, his hatchet face
thunderous. "I've warned you often enough, Bailey. This time you've
gone too far."

Shanig treated himself to one of his sandpaper chuckles. "He'll
probably give you some wild story designed to clear himself,
Captain. Don't believe a word of it. I trusted him, and you can see
what it led to!"
The Captain was taking my Quantrell blaster when my reprieve
came. One of Shanig's uglies burst into the office with disaster
written all over him.
"Chief, the girl's coming up in the lift with another smiley! The whole
lower floor is hypnotized. She'd have got me too if the lift hadn't
carried me out of reach!"
I'll give Shanig credit for this—he thought fast. He added up the
score in a flash and lunged across the desk, yelling for his startled
uglies to follow up. If Cheryl got to us with the smiley the jig was up,
and he knew it.
He ripped the Quantrell blaster out of Captain Giles' hand and turned
it on us. He meant to wipe out the lot and clear himself by laying the
carnage to a battle between me and the patrol.
It was close, but not close enough.
A sudden serenity wiped the tension off his face like chalk marks off
a blackboard. Captain Giles and his patrolies slacked off with him,
caught in the same euphoric spell.
They stood smiling and docile while Cheryl Trayne strode in with
Cora's little tungsten cage under her arm. If she had looked good to
me before, right then she looked like a red-haired angel.
"Good girl," I said, and took over from there.
Shanig confessed on the spot to the slimy deal he had pulled over
me, and signed a statement to that effect. He got on the reception-
room phonovision and ordered his crew in the adjoining building to
drop everything and return Perry Acree at once. He destroyed the
bogus contract and took back the elastic check he had given me,
and he enjoyed doing it. Cora, sensing Joey so close in the Argonaut
Bar across the street, was working her mating call overtime.

"It was really inconsiderate of you to swindle our young friend
William," the Captain said to Shanig. "Of course you won't object to
serving a light sentence—say five years—to make amends?"
"Certainly not," Shanig said brightly, beaming back at him. "My only
regret is that I must be separated from this adorable creature. I love
smileys."
He went over to the desk where Cheryl had left Cora's cage and
fondled the little brute through the wires. He played the very devil in
doing it, too. Somehow or other the cage door had worked loose
during the time it had been banged about, and Shanig's fumbling
hands slid it open.
Cora was out of the cage and through the broken balcony windows
in a smoky bluish flash, whizzing like a bullet toward the Argonaut
Club and Joey.
VI
Everybody snapped back to normal with a roar. There was a frantic
rush of Shanig's uglies trying to escape and of Giles' patrolies
collaring them again. I took no chances with Shanig. I turned my
Quantrell on him and held him fast.
Hell broke loose in the Argonaut then. Even before the confusion
quieted in Shanig's office we could hear the din that went up across
the street.
From our balcony windows we had a grandstand view of the
Argonaut's more timid patrons exploding out of the place and
tearing down the street, wobbling and lurching each in his own
outlandish fashion from the assortment of Eetee drinks they had
taken aboard under Joey's spell. The rougher souls left inside had
begun a battle royal that raised a bedlam wilder than a robot rooting
section at a rocket-games stadium.

"What is it!" Captain Giles yelled, goggling at a barrel-bellied
Europan who shot out of the Argonaut with a pack of little baboon-
faced Marties harrying its speeding cart from the rear. "What have
you done now?"
"Shanig has just ruined a forty-thousand-credit investment for me," I
told him, "by letting my pair of smileys get together. That peace-be-
on-you feeling they've been broadcasting is a thing of the past. They
feel just the opposite now, and so will anyone who goes near them."
I had to explain it twice before they got it.
Mimasan smileys, as I've said before, are weird little brutes.
Unmated, their euphoric mating calls attract them to each other and
at the same time protects them from native predators. The catch is
that when they mate they coalesce, each complementing the
insubstantiality of the other to become a single material entity.
And then, of course, there's no further need of their wistful, coaxing
aura.
After that they hate everybody, being newlyweds and not wanting to
be disturbed, so of course they radiate an exactly opposite aura that
guarantees them the privacy their joint little heart craves. Nothing
can come near enough to interrupt them without becoming so
rabidly angry that it has to rush off somewhere else looking for
something to fight. But you see how it goes.
"And from the row going on in the Argonaut," I finished, "I'd say
that Joey and Cora are definitely on their honeymoon."
"You mean they'll be like that always?" Cheryl asked, wide-eyed.
"That no one can go near them without flying into a rage?"
"Not always," I said glumly. "Just for five years. After that they
divide by fission into a dozen or so baby smileys, and after that the
rat-race starts over again. The progeny will be worth plenty, but
who's going to stand guard over that amalgamated little demon
while it broadcasts hate and damnation in every direction? I won't,

and there's not a homo in the System that would take the job for
love or—"
The answer hit me like a thumb in the eye, bang in the middle of a
sentence.
"Captain Giles," I said. "I've a suggestion that...."
The Captain got it on first bounce. For the first time in history he
laughed without benefit of smiley.
It worked out neatly enough, at that. An Areopolitan court decreed
that Shanig, being bound by the requirements of Martian law to
expiate his crimes with as little expense to the polity as possible,
should spend the five years of his sentence guarding Joey-Cora in a
force-wall detention area to be set up in Syrtis Major. By the time his
term ended my combination smiley would have fissioned, Shanig
would have paid his debt to society and my investment would have
paid dividends.
It could have been worse. For the time being I was out some forty
thousand credits, but I managed to salvage enough for a moderate
celebration by contracting with the government to furnish khiff roots
from Mimas to keep Shanig from going berserk under Joey-Cora's
influence.
The arrangement wasn't too hard on Shanig, even. The worst of it
would be the isolation—that, and the packs of Syrtis Major jackals
that would crowd around the force-wall at night and howl for his
blood.
"Good enough," I told Cheryl after the trial. "That leaves just one
small detail to be arranged. I'll have to wangle another loan from
Martian Bankings."
She raised a slim brow. "Loan? For a grubstake?"
"For our weekend on Phobos," I said. "Remember?"

She laughed. "There's another little detail you overlooked, William.
My ring size is five and one-half."
"Ring?" I said. "Oh, a ring.... Would you rather have a Tellurian
diamond, an A-belt fire-opal, or—"
"Nothing expensive," she cut me off. "Something simpler would be
more appropriate, I think. Under the circumstances, I'd suggest a
plain gold band."
I gaped at her like a swamp-guppy until it seeped through my skull
that she was in dead earnest.
"Wait up," I said. "What about Perry Acree?"
She snapped her fingers. "That for Perry. I thought I wanted the
little creep until you brought him back, but after that I couldn't bear
the sight of him."
"You mean," I said, grasping at any straw, "that you really want to
be—"
"Married," she said definitely. "First and firmly, or no Phobos trips!"
"It wouldn't last," I argued. "Being an A-belt prospector's wife is no
snap, Cheryl. I'd be out in the Annabelle for weeks on end,
slamming around in God knows what kind of dangers. And one of
these days I wouldn't come back at all and you'd be a widow."
"You wouldn't be slamming around," she corrected me softly. "We
would, Willie dear. I'd be with you every minute."
That did it. It was "Willie dear" already, and she'd be with me every
minute. Even in port....
"I'll have to give this some serious thought," I said. "Look, you
wouldn't want us to plunge into a deal that wouldn't work out, would
you?"
"Of course not," she said with a demure certainty that made my
blood curdle. "But this will work, Willie darling. I'll see to that."

I got out of there and went down to Martian Bankings in the devil of
a hurry. They were apologetic over selling my grubstake lien, and
were glad to advance me a few thousand credits against Joey-Cora's
expectations.
For once I passed the Argonaut Club without even looking back. A
homo with a skinful of skohl is short on resistance, and resistance
just then was what I needed most.
When I reached the blastoff aprons, the Annabelle's rusty old hulk
was the sweetest sight I ever saw. I pointed her lovely, meteor-
dented nose at the sky and blasted off, and the howling of her jets
was like a lullaby in my ears. The starry backdrop of space ahead
was like a cosmos-sized painting of all Creation, a master canvas
done.

Section 2. Information about the Mission
of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers.
It exists because of the efforts of hundreds of volunteers and
donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg™’s
goals and ensuring that the Project Gutenberg™ collection will

remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a
secure and permanent future for Project Gutenberg™ and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help,
see Sections 3 and 4 and the Foundation information page at
www.gutenberg.org.

501(c)(3) educational corporation organized under the laws of the
state of Mississippi and granted tax exempt status by the Internal
Revenue Service. The Foundation’s EIN or federal tax identification
number is 64-6221541. Contributions to the Project Gutenberg

Section 4. Information about Donations to
the Project Gutenberg Literary Archive
Foundation
Project Gutenberg™ depends upon and cannot survive without
widespread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can
be freely distributed in machine-readable form accessible by the
widest array of equipment including outdated equipment. Many

small donations ($1 to $5,000) are particularly important to
maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and
keep up with these requirements. We do not solicit donations in
locations where we have not received written confirmation of
compliance. To SEND DONATIONS or determine the status of
compliance for any particular state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where
we have not met the solicitation requirements, we know of no
prohibition against accepting unsolicited donations from donors in
such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of
other ways including checks, online payments and credit card
donations. To donate, please visit: www.gutenberg.org/donate.
Section 5. General Information About
Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project
Gutenberg™ concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg™ eBooks with only a loose network of
volunteer support.

Project Gutenberg™ eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.
Most people start at our website which has the main PG search
facility: www.gutenberg.org.
This website includes information about Project Gutenberg™,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how
to subscribe to our email newsletter to hear about new eBooks.
