The ANT task WsJpaDB2GenTask provides an alternative to the wsdb2gen command, allowing users to utilize the pureQuery feature in Java Persistence API applications.

Both the PDQ runtime JAR files...

• pdq.jar
• pdqmgmt.jar

...must be specified using the ANT -lib option.

 

Example

The example listed below could be run with the ANT command using the following:

<!-- invoke this build using the ANT command 
ant jar -noclasspath -lib c:/was7/lib/j2ee.jar 
        -lib c:/was7/plugins/com.ibm.ws.jpa.jar 
        -lib c:/sqllib/java/db2jcc.jar 
        -lib c:/sqllib/java/db2jcc_license_cu.jar 
        -lib c:/sqllib/java/pdq.jar 
        -lib c:/sqllib/java/pdqmgmt.jar 
--> 

When calling the ANT command, the JAR files for pureQuery, JPA, and the JDBC driver must be on the library list.
