8.6.4 Create the filter
A filter is simply an EJB running in an enterprise application. To create the filter,
do the following steps with WebSphere Studio:
1. Create an enterprise application. (ITSORouterApp in the scenario).
2. Create an EJB project. (ITSORouterAppEJB in the scenario).
3. Create a session bean. (RouterBean in the scenario). The easiest way is to
use the J2EE Hierarchy view in the J2EE perspective. Select the Session
Beans folder, right-click, and select New->Session Bean. The values we
used are shown in Figure 8-19 and Figure 8-20.

Figure 8-20 Create a session bean for the filter
When you create an EJB filter, you have to use the following interfaces:
– com.ibm.wsgw.beans.FilterHome
– com.ibm.wsgw.beans.FilterRemote
Tip: To develop the filter, you need to have the wsgwejb.jar, which comes in
the <WAS_Enterprise_HOME>/lib directory in your build path.
Important: The support of filter programming is supported only in IBM
WebSphere Application Server - Enterprise.
