Introduction
Oracle WebLogic Server is the #1 application server across conventional and cloud environments. As
a JEE-compliant server with enterprise-class features, WebLogic Server is the premier option for
mission-critical and highly-available applications. Leading Independent Software Vendors (ISVs) and
System Integrators building their own IP use WebLogic Server along with Oracle Database as the core
deployment platform for their Java Applications. Oracle WebLogic Server provides capabilities which
allow ISVs to accelerate the development cycle and reduce time-to-market for their applications while
also lowering the total cost of ownership for their customers. Oracle WebLogic Server is also the
foundation for the Oracle Fusion Middleware technology stack - the only middleware available from
any vendor that provides a complete, open and integrated approach across social, mobile, and cloud
technologies.
ISVs license Oracle WebLogic Server under different distribution agreements but one of the most
popular programs from Oracle is the Embedded Software License (ESL) Distribution Agreement.
Embedding is the processes of packaging WebLogic Server within an ISV application in a manner that
makes the presence of WebLogic Server invisible to the end user of the application. This allows ISVs
to provide WebLogic Server as a “black box”, reducing the support overhead associated with end
customers making unwarranted changes to the technology infrastructure. Further benefits include
simplifying the installation & maintenance of the application and the underlying technology
infrastructure. Oracle also has aggressive discounts available under the ESL program.
This white paper is intended to guide a partner through the Oracle WebLogic Server embedding
process with an eye towards ESL compliance. Use this paper in combination with sample scripts in
the Appendix and documentation pointers to create your embedding strategy. Documentation links are
for Oracle Fusion Middleware 11gR1. Version specific documentation for Oracle Fusion Middleware is
available on OTN http://www.oracle.com/technetwork/middleware. Similarly, scripts should be
edited & tested based on specific deployment environment.

Embedding WebLogic Overview
The technical process of embedding involves encapsulating the installation and management of the
embedded components through the use of silent installation & API/script based management
techniques. Embedding WebLogic Server involves planning 4 different areas –
 Installing WebLogic Server silently with ISV Application
 Creating & Configuring WebLogic Server Domains through scripts
 Deploying the ISV Application on WebLogic Server through scripts
 Managing & Monitoring WebLogic Domain & Servers through scripts or java code which can
be called if needed from the ISV’s Application Management Console.

2


Patching of the embedded WebLogic Server should be done using the SmartUpdate tool. Other Oracle
Fusion Middleware components use OPatch and in the future WebLogic Server will also support the
OPatch utility.

Silent Installation
Silent installation of WebLogic Server is typically embedding requirement number one. An overview of
WebLogic installation is available in the installation guide. Silent installations have been part of the
installation and deployment strategy at Oracle for many years. Simply stated, silent installation is a
method by which Oracle WebLogic server is installed in a manner that requires zero interaction by the
person doing the installation. In a silent installation, no installation forms or feedback screen is given.
All options and configurations are controlled in xml file(s). In a situation involving an embedded
software license, the partner application should call the silent installation directly from within its own
installer, thus completely hiding the WebLogic Server installation. A silent installation is not unlike a
standard installation as it is dependent on system prerequisites.
The silent.xml file is the main driver of the silent installation process. It is where one configures how
WebLogic Server is installed. This file can be parameterized to support inputs from another installer
such as an ISV’s installation process thus allowing input from those forms to dynamically fill out a
silent.xml for use in silent installation. A sample silent.xml is available here.
Without replicating the comprehensive documentation linked earlier, suffice it to say there are three
ways to start a silent installation.
 A bin installation for *NIX platforms
 A jar installation for generic platform installations (perhaps the easiest if your application runs
on many different platforms)
 An exe installation built for Windows targets
Each installation is the same package one would use for an interactive installation with the addition of
a flag identifying it as silent (-mode=silent) and a pointer to your silent.xml (-silent_xml=<path>). The
following link describes the installer files used for each platform. Please remember each could be used
for interactive as well as silent installations so flagging the mode is critical.

Domain Creation & Configuration
The WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to
create, manage, and monitor WebLogic Server domains. It is based on the Java scripting interpreter,
Jython. You can also instantiate WLST in Java code and use it to run WLST commands and scripts.
WLST enables you to create a new WebLogic domain or update an existing WebLogic domain without
connecting to a running WebLogic Server. This can be done in two ways -

3


 Creating and Using a Domain Template (Offline)
A configuration template defines the full set of resources within a domain, including infrastructure
components, applications, services, security options, and general environment and operating
system options. Oracle provides a number of templates and template extensions as part of the
WebLogic Platform product. Appendix A provides a WLST offline configuration script to create a
simple clustered WebLogic domain using the Basic WebLogic Server Domain template. Domain
Template Builder is a standalone Java tool to create templates which can then be applied in the
offline creation of WebLogic Server domains. An ISV can create a standard domain template using
Domain Template Builder. Domain Template Builder accomplishes template creation based on an
interactive GUI, pack and unpack provide a scriptable, command-line utility.
 Using the configToScript Command
WLST includes a command, configToScript, which reads an existing WebLogic domain and
creates a WLST script that can recreate the WebLogic domain. This option requires a running
WebLogic Server instance.

Application Deployment
Application deployment on WebLogic Server is the process of distributing an application for server-
side processing and application startup. Oracle Fusion Middleware deploying applications to WebLogic
Server guide provides in depth documentation for all aspects of deployment.
WebLogic server can support various deployment units: enterprise application, web application, EJB,
resource adapter, web service, Java EE library, JDBC, JMS, WLDF modules and so on. Before
deploying, we need to prepare applications and modules for deployment. WebLogic Server supports
deployments that are packaged either as archive files (.ear, .jar, .war, and so forth) using the jar utility,
or as exploded archive directories. In stable production environment, we would recommend to use
archive files, since they are more efficient for deploying applications to managed servers. Although you
can deploy to the Administration Server in a multiple-server domain, this practice is not recommended
except during development.
The WebLogic Administration Console, weblogic.Deployer tool, wldeploy Ant task, and WLST all
provide similar functionality for deploying applications. Use WLST when you want to create
automated scripts that perform deployment tasks. Use weblogic.Deployer to integrate deployment
commands with existing administrative shell scripts or automated batch processes. Use wldeploy in
conjunction with the split development directory for developing and deploying new applications.
wldeploy can also be used in place of weblogic.Deployer in administration environments that use Ant,
rather than shell script.

Deploying Applications with WLST
We can use either WLST online or offline to deploy applications:

4


 WLST offline - If the WebLogic Server is not running, for example the WebLogic domain
was just created or the Admin server and managed servers are not started yet. In this case, we
have to use WLST offline. A sample script is available in Appendix B.
 WLST online - If the WebLogic Server is running, this method is highly recommended. A
sample script is available in Appendix C.

Deploying Applications with weblogic.Deployer
weblogic.Deployer provides a command-line based interface for performing both basic and advanced
deployment tasks. Common Deployment Scenarios with weblogic.Deployer is available here.
weblogic.Deployer commands and command options used to perform deployment tasks with
WebLogic Server are available here.
Example –
C:>java weblogic.Deployer -adminurl t3://localhost:7001 -username weblogic -password welcome1 -
name ShoppingCart -targets examplesServer -deploy C:ShoppingCart.war
The connection arguments are “-adminurl t3://localhost:7001”; the user credential arguments are
organized as “-username weblogic -password welcome1”. In this sample command, the command
arguments used are “deploy”, “targets” and “name”.

Server Administration
Management
During its lifetime, a server can transition through a number of operational states, such as shutdown,
starting, standby, admin, resuming, and running. Server lifecycle management in an embedded
environment requires non-interactive, script-based management techniques. Silent stopping and
starting of domain servers such as administration and managed servers is typically just a matter of
script execution in a Linux and UNIX environment. The same is true of Windows environments as
well but with the option of creating a service to start and stop the servers. The following link describes
how to start and stop WebLogic Server using WLST. Similarly, other Server operations can be done
using WLST -
 Appendix D illustrates how to instantiate the WLST interpreter in java and use it to connect
to a running server, create two servers, and assign them to cluster.
 Appendix E provides steps to change server runtime parameters.

Monitoring
Java Management Extensions (JMX) is a specification for monitoring and managing Java applications.
It enables a generic management system to monitor your application; raise notifications when the
application needs attention; change the state of your application to remedy problems. A managed bean

5


(MBean) is a Java bean that provides a Java Management Extensions (JMX) interface. WebLogic
(WL) provides MBeans for both admin and managed servers. Sample code to read server information
is provided in Appendix F. WebLogic Server also provides RESTful Services to monitor Server,
clusters, Applications, and Data Sources. More details are available here. Partners can use the JMX or
REST APIs to implement customized monitoring solution for WebLogic.

Conclusion
Embedded WebLogic have many benefits, not only for ISVs and OEMs developing a business
application, but also for their end users or customers. Embedded WebLogic enables ISVs to build
critical technology into their products for higher cost savings, improved management control, and
greater efficiency. For end users, embedded WebLogic offer high performance and rapid installation
with lower IT and support costs.
This white paper outlined steps for embedding Oracle WebLogic Sever. A similar white paper for
embedding Oracle Database is available here on OTN. While this document addresses Oracle
WebLogic Server, other components of Oracle Fusion Middleware can be embedded in a similar
manner. The benefit to ISV partners and their customers in the adoption the Oracle Fusion
Middleware stack include fast time to market and lower total cost of ownership.

Appendix
Appendix A – Domain Creation & Configuration

#=======================================================================================

# This is an example of a simple WLST offline configuration script. The script creates

# a simple clustered WebLogic domain using the Basic WebLogic Server Domain template. The script

# demonstrates how to open a domain template, create and edit configuration objects,

# and write the domain configuration information to the specified directory.

#

# This script is an adaptation of several delivered sample WLST scripts that come with

# your WLS installation as well as some code from additional sources.

#

# (WL_HOME refers to the top-level installation directory for WebLogic Server.)

#

# The sample consists of three managed servers, representing a simple single-node cluster for a development environment.

# Use of this script without editing and strenuous testing is not recommended (and IN NOT SUPPORTED) for production environments.

#

# Please note that some of the values used in this script are subject to change based on

# your WebLogic installation and the template you are using.

#

# Usage:

# java weblogic.WLST <WLST_script>

#

# Where:

# <WLST_script> specifies the full path to the WLST script.
