Running the JPA entity test

Now we can run the test:

Make sure that the ITSOBANKderby connection is disconnected (with Embedded Derby you can only have one active connection to a database). You can verify this in the JPA perspective, Data Source Explorer. If the connection is active, right-click the connection and select Disconnect.

Right-click the EntityTester class and select Run | s Ć Java Application.

You receive error messages in the Console that the Customer class cannot be found.

Select Run Ć Run Configurations. You can find the EntityTester configuration under Java Application.

Select the Arguments tab.

For Program arguments, type 333-33-3333 (we want to work with that employee).

For VM arguments, type (use the installation directory):

-javaagent:c:/IBM/SDP75/runtimes/base_v7/plugins/com.ibm.ws.jpa.jar

Note: OpenJPA includes a Java agent for automatically enhancing persistent classes as they are loaded into the JVM. Java agents are classes that are invoked prior to your application's main method. OpenJPA's agent uses JVM hooks to intercept all class loading to enhance classes that have persistence metadata before the JVM loads them.

Figure | 2-13 shows the run configuration arguments.

Figure 12-13 Run configuration arguments

Click Apply, the click Run. The Console displays the output (Example | 2-11).
