Mule esb
- 2. 2 Mule Enterprise Service Bus Support for more than 30 protocols and technologies Simplified POJO-based programming model leveraging existing developer skill-sets for fast deployment Support for multiple access points such as JMS, JDBC, and SOAP No reliance on vendor-specific proprietary protocols Ease of use – services can be configured easily in one configuration file. Extensive data transformations out of the box Small footprint: memory and disk, no application server required Integration platform model: highly modular, easily extensible codebase - implement proven patterns and build streamlined solutions to unique challenges The open source advantage: large community of real-world integration experts and developers using Mule and contributing to codebase
- 3. Mule ESB Flow Mule ESB is a lightweight Java-based enterprise service bus (ESB) and integration platform that allows developers to connect applications together quickly and easily, enabling them to exchange data. Mule ESB enables easy integration of existing systems, regardless of the different technologies that the applications use, including JMS, Web Services, JDBC, HTTP, and more. The key advantage of an ESB is that it allows different applications to communicate with each other by acting as a transit system for carrying data between applications within your enterprise or across the Internet. Mule ESB includes powerful capabilities that include:
- 4. 4 Prerequisite Build Tool You must also install the Mule IDE with Eclipse (recommended), Maven, or Ant, depending on which tool you want to use to build and run your projects. Mule IDE If you will install the Mule IDE, you install it after installing Mule--see Installing Mule IDE. Maven If you do not want to use the Mule IDE, or if you will be using the Maven archetypes to create a new transport or module, install Maven.
- 6. Mule use to transport to receive and send message from and to all kind of source including Java Messaging service (JMS), HTTP, FTP, TCP/IP,SMTP,POP3 and file. Another important concept of mule is the service definitions which consist some specific layers that can be solve the integration of multiple protocol and application’s communication problems. Application Channel Message Receiver Connector Transformers Inbound Routers Component Outbound Routers Message Dispatcher Mule Component Overview
- 7. Application: This identified the application we are integrating with Mule. It can any thing an old legacy COBOL system, a .net application, a j2ee application, or even another mule instance. Channel: Channels (an enterprise integration pattern) provide a way for external application to communicate with mule. channel can also be used to inside mule to wire service together. Message Receiver: This component can receive info from a certain channel Connector: Connector under how to send and receive data from certain channel, and connect present to both of side sender and receiver end. Connector have two components.
- 8. Message Receiver Message Dispatcher Transformers: Transformers transform the data one form to other form . Inbound Router: it can determine what to do with a message once it’s receive from channel. Component: The component is the logic place with mule architecture to implement integration logic not provided by other mule parts. a component can be implemented with a no. of technologies like POJO(plane old java objects), groovy script, REST services, BPM and among others. Outbound Router: this is much same as the inbound routers but component determines where a message is sent after it’s proceed by component.
- 9. Configuration Terms Of Mule ESB Model :The first logical layer is the model layer. A Mule model represents the runtime environment that hosts services. It defines the behaviour of Mule when processing requests handled by these services. the model provides services with supporting features, like exception listeners. It also provides services with default values that simplifies their configuration.
- 10. Service: A Mule service is constituted of all the Mule entities involved in processing particular requests in predefined manners, To come to life, a service is defined by a specific configuration. This configuration determines the different elements, from the different layers of responsibility, that will be mobilized to process the requests that it will be open to receive. Depending on the type of input channel it uses, a service may or may not be publicly accessible outside of the ESB.
- 11. Transport: The transport layer is in charge of receiving or sending messages. This is why it is involved both for inbound and outbound communications.
