Comprehensive example in Open ESB using File, FTP, JMS, JDBC and Soap

The last 5 articles explains different binding components (File, FTP, Soap, JDBC, JMS) usage in Open ESB. To summarize and get more understanding of each of this BC, here is a comprehensive scenario using all of these binding components. Let's define a problem that requires to use all these BCs.

Problem Description: Get the employee details from the database based on employee id and publish it in JMS. There will be two different subscribers who listens to JMS and consumes the message based on some filter logic and publish the message either on local file or on FTP server. The whole solution should be exposed as a web service so that it can be accessible to any web service client.

Let's assume that you have to implement this solution in normal application like Java/.Net. You'll have to take care of the following major things apart from business logic

• Management of Database connections
• Management of JMS connections
• Management of FTP connections
• Management of File streams
• Web service implementations

In case, you are using SOA application all of the above are taken care by the respective binding components and user can only concentrate on the business logic.

SOAP BC in Open ESB

This article describes the instructions of SOAP BC usage in association with BPEL SE in OpenESB.

SOAP Binding Component provides external connectivity for SOAP over HTTP and BPEL Service Engine allows users to implement the business logic in the BPEL flow.

Objective:

The objective of this exercise is to implement the Business Process to receive the Soap request from client, do transformation and send back the Soap response to client. Soap Binding Component used to receive the soap request and send back the soap response and BPEL Service Engine helps for transformation and other business logic.
