Hi guys in this post we are going to create a Simple Pass through Proxy in Oracle Service Bus. I hope you have successfully setup your OSB configuration project, if not please follow my previous post here. Now moving on to Develop your first OSB project.
Step 1--> Right click on your OSB configuration project and select Oracle Service Bust project

Step 2--> Give it a name. I have given Calculator since i am going to connect OSB to an external web service(calculator). U can give any name.

Step 3--> Now right click on ur Project and create four folders i.e, WSDL, Proxy, Business Service and XSD. Its always a good practice to keep all your files in respective folders.

Step 4--> Now copy XSD and WSDL files of your existing service in respective folders.[Note: You need working WSDL and corresponding Schema files of an existing service. i.e you need a running web service  which you want to call from your OSB. You can get free web service WSDLs from here ]

Step 5--> Now right click on Business Service folder and new Business Service give it a name. I have given CalculatorBusinessService.

Step 6--> Now Select WSDLweb service--> browse--> provide wsdl file location-->Select port of your WSDL. Finish and override previous transport configuration.

Step 7--> Now right click on Proxy folder and create new Proxy service. Give it a name. I have given

Step 10-->Drag a routing node from Route Actions

Step11--> In Routing Service* provide a link to your Business Service. So that your Proxy directly routes to the Business Service.

 Click on ok .

Now You are ready to deploy your OSB project. To deploy right click on configuration project and run as server.

Work Flow:
Client--> Proxy Service-->Business Service--> External Service
1) Business  Service: Wraps the external Web Service and provides an extra layer of abstraction .
2) Proxy Service: Routes requests coming from Client to that Business Service. And provide response back to client
