Oracle Service Bus - A Sample demo project in 12c

In this article, we will go through the detailed steps for creating/developing/constructing and testing demo Service Bus project using JDeveloper 12c.


With 12c, we no longer required to install Eclipse IDE separately (OEPE –> Oracle Enterprise Pack for Eclipse) to develop OSB modules.


Instead we can develop Service Bus projects within JDeveloper IDE.

Let’s get started with designing the OSB project in JDeveloper 12c IDE

Step 1: 

Open a New Application:

Application Menu –> New or File Menu –> New –> Application

Step 2: Select Service Bus Tier from available categories

Service Bus Tier –> Service Bus Application with Service Bus Project –> OK

This opens up wizard for Service Bus Application

Step 3: Enter the Application Name and its directory location for the new Service Bus Application

Leave the default values for demo; otherwise we can give more specific names in accordance to naming convention followed in the project

Click Next

Step 4: Similarly, enter Project Name

We can leave the default values for demo; or else we can give some name

For example, HelloWorldSB

Click Finish

New Service Bus project is created with required artifacts

Step 5: As this OSB module is simple mock service to return hello to the entered user, we will concentrate on the exposed service side i.e.; Proxy Service

Drag HTTP component from Technology palette and drop at Proxy Services lane –> which opens up new wizard to enter necessary details for the Proxy Service

Enter Proxy Service Name: HelloWorldProxyService

Transport: http (actually, there is no other options available)

Check “Generate Pipeline” options with default pipeline name or some more conventional name in accordance with the project standards

Click Next

Step 6: 

Second step of wizard to create a contract –> we will create new WSDL for contract with single input for user to enter their name and single output for returning a greeting message with hello appended with the user name

Follow below steps to create a new WSDL using wizard

In the Interface Type, choose “Synchronous Interface” from two options available –> which will enable the input, output and fault elements to be entered for inputs, outputs and faults respectively

Note: Click green plus icon to add the required elements for input, output and fault (on right-top-corner)

Click OK

After entering necessary details for WSDL contract –> output will have new WSDL auto-populated in the Create Proxy Service wizard of step 2

Click Next

Keep the default value which comes populated for the Endpoint URI or else you can change as per business requirement

Click Finish

Finally there will be HTTP component on the Proxy Service lane and Pipeline component on the Pipelines/Split Joins lane

Step 7: Double-click on the pipeline component in the Pipelines/Split Joins lane

Opens up “.pipeline” file in the editor

Step 8: Drag “Pipeline Pair” from Message Flow under “Nodes” category

Step 9: Drag “Replace” node from Message Flow under “Message Processing” category

Step 10: Add “concat” function in the replace node

Click OK

Step 11: Service Bus project design is completed according to the business requirement

Take a look at the Replace node properties

Step 12: Testing the Service Bus project deploying into the IntegratedWeblogicServer

As designing the Service Bus project is complete, it’s time to deploy the project into the IntegartedWeblogicServer and test them

This will open our traditional OSB console, where we can input and execute this sample mock service. Enter necessary detail in the Request document –> Click Execute

Request document and Response document

The same can be tested through Service console (OSB console) at http://localhost:7101/sbconsole (change the port number, if you have configured something else)
