Echo Service

In this tutorial we will develop simple Echo service using Netbean tooling support for the POJO Service Engine.
We will create a Composite Application so that BPEL will be used to invoke POJO service. We will also use Composite Application project's tester to test our Service.

Since originally written, some of the API classes have changed, but in most part this sample/tutorial should work. You can find more details of API changes here and here.

Software/Tools needed

• Open ESB Netbeans IDE. Use nightly or milestone installer to install Netbeans IDE, Glassfish server and JBI runtime along with some of the JBI components.
• POJO Service Engine
• Netbeans tooling support: Download and install Netbeans modules "org-netbeans-modules-soa-pojo.nbm" and "org-netbeans-soa-libs-pojo.nbm"

Create a Java Project

POJO Service Engine support is added to Netbeans Java SE project. After installing Netbeans and Glassfish using the Open ESB installer, create a Java SE project.

Create POJO for Binding.

Right click on the project node, select new File/Other wizard, select ESB from Categories and select POJO for Binding from the File Types.




Choose File BC - Poll & Write back reply



Click next configure input file ( say c:\temp\input.xml) and output file ( say c:\temp\output.xml)





Click next and configure POJO class.



Click Finish.

Create a Composite application project

Add Java SE project just created to this Composite Application project.



Invoke "clean and build" ant target on the composite application project.



We just completed the creation of POJO service for File Binding Component and a composite application.

Start the server

Before we deploy the Composite Appication, make sure POJO Service Engine is installed and started. Navigate to server tab, select server node, select "Start"



If POJO Service Engine is not installed, download and install the engine.

Test the application

Now we are ready to create a test and test the application. Create an input.xml in c:\temp containing any data. As soon as the file is created File BC polls the input file and invokes the POJO service. After a while you will see output.xml generated in c:\temp continaing same data as input.
