ANT task WsJpaDB2GenTask

The ANT task WsJpaDB2GenTask provides an alternative to the wsdb2gen command.

The WsJpaDB2GenTask ANT task utility allows users to utilize the pureQuery feature in Java™ Persistence API (JPA) applications. Instead of executing the wsdb2gen from the command line, you can use the example code in your ANT build XML file to use the WsJpaDB2GenTask in your build process.

Both the PDQ runtime Java archive (JAR) files, pdq.jar and pdqmgmt.jar, must be specified using the ANT -lib option.

Attention: Read more about the DB2 JAR level compliance for pureQuery at the IBM Support Website: System requirements for IBM Optim pureQuery Runtime for Linux, UNIX, and Windows.

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.
