Setting up the build path for OpenJPA
Because this class runs outside of the server, we have to add the required JPA and server libraries to the build path.
| Right-click the RAD75JPATest project and select Properties. |
|
| In the Properties dialog, select Java Build Path (on the left) and the Source tab. Change the output folder from RAD75JPATest/bin to RAD75JPATest/src (Figure | 2-8). Without this change, the persistence.xml file that we create will not be found. |

Click Add Variable.

In the New variable Classpath Entry dialog, select ECLIPSE_HOME, and click Extend (Figure | 2-10).

In the Variable Extension dialog, expand runtimes Æ base_v7 Æ lib, select the j2ee.jar, and click OK (Figure | 2-11).

|
Repeat this sequence by extending the ECLIPSE_HOME variable, and select these JAR files:
|
runtimes/base_v7/derby/lib/derby.jar
runtimes/base_v7/plugins/com.ibm.ffdc.jar
runtimes/base_v7/plugins/com.ibm.ws.jpa.jar
runtimes/base_v7/plugins/com.ibm.ws.prereq.commons-collections.jar
|
The Libraries tab shows now the extra JAR files (Figure | 2-12).
