In this article, we will go through the detailed steps for creating/developing/constructing and testing demo Service Bus project using JDeveloper 12c IDE
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 itself where we normally construct SOA modules including BPEL, Mediator, Business Rules and Human Task
Refer Oracle SOA 12c installation article for more details
1. Business case requirement :
- This will be a mock service where end user enters name
- And expects a response in the format of “Hello <entered_name>”
As the requirement is to just return the Hello message appended with user name entered, there is no need to design Business Service or External Service
In the next article, we will improve this design by exposing a separate Business Service and then connecting link with Proxy Service
Let’s get started with designing the OSB modules in JDeveloper 12c IDE
2. Hello World mock service with Proxy Service :
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)
