Manipulating the response of the JEJB transport by a Java Callout action

In this recipe, we show how to change the response and enrich the message by a value for the rating attribute. For that, we have to create a Java class that we will call from the message flow of the proxy service through a Java Callout action:

We have created a simple Java class as shown in the following screenshot:

As we can see, this Java class has one method, which enriches the value of the rating attribute of a customer object based on the value of the first name attribute. The method accepts a parameter of type Object and cast this to a Customer type.

To make it available to OSB, we have to package the Java classes into a JAR. This JAR is available as enrichment.jar in the ejb-jdev-workspace\ejb\deploy folder.

Getting ready

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

Import the base OSB project containing the necessary schemas and the right folder...
