5.4.3 Testing and running the scenario

You can test the retrieval of the company list using an EJB proxy and JUnit test

class.

Generating EJB proxy

Generate an EJB proxy which exposes the service through a Java class.

1. Right-click the TraderblEJBService.wsdl file. Choose Enterprise Services

→ Generate service proxy to launch the Generate Service Proxy wizard.

2. Choose WSIF and click Next.

3. Accept the defaults, including, class name TraderblProxy.java. Click Next.

4. Select client stub, then select the retrieveCompanyList() operation. Click

Finish.

This proxy class uses WSIF to invoke the EJB retrieveCompanyList operation.

Generating JUnit test case

Add the junit.jar to the project, then use the JUnit Test Case wizard to create the

test class.

1. Change to the Java perspective. Right-click the CICSJCAEJB project, then

select Properties.

2. Select Java Build Path, then the Libraries tab. Click Add External Jars.

3. Navigate to the ..eclipse\plugins\org.junit_3.8.1 folder and choose junit.jar.

Click Open.

4. Click OK to add the JAR to the project’s Java Build Path.

5. Select TraderblProxy in the CICSJCAEJB project.

6. Right-click TraderblProxy then choose New

→ Other.
