Go to the message flow tab, from the design palette drag and drop Route activity into the process flow diagram after FileRoute activity.

Drag and drop routing activity after the route node. (Select from Route Action – Communication->Routing)

JDeveloper 11g – Creating PL/SQL Webservice and deploying to Weblogic Server

You can expose PL/SQL stored procedures as Webservice via JDeveloper(which wraps the PL/SQL code into Java wrapper), and you can deploy it into weblogic server.

1. Open JDev 11g and create a database connection to HR schema(a sample schema that contains the PL/SQL procedure).

4. Accpet the default and start once finished start the Weblogic Server, here im using the embedded weblogic server in the JDeveloper 11g.

5. Login into Weblogic console and create a datasource connection.

Name – hrconnDS
JNDI Name – jdbc/hrconnDS
Donforget to DS suffix.

6. Deploy the application to the Weblogic Server from JDeveloper11g.

7. Test the Webservice from Weblogic console, through the Weblogic test client.
