Exposing an EJB session bean as a service on the OSB using the EJB transport

As the version of OSB is 11gR1 we can use an EJB version 3.0 session bean in an OSB business service. Before 11gR1, only EJB version 2.1 was supported.

In this recipe, we will create and test a business service—JB and JEJB transport. The business service calls a session bean that returns the Java object in XML or as a Java object with the JEJB transport.

Getting ready

Make sure that the EJB session bean is deployed to the OSB server as shown in the Introduction section of this chapter.

In Eclipse OEPE, perform the following steps:

1. Create a new OSB project and name it exposing-session-bean-as-webservice and create a jar, business, and proxy folder within it.

2. Open a file explorer window and navigate...
