Description

Hi All,

While building the project I'm using the following script in build.xml to Enhance the classes using the openJPA enhancer. I am getting exception while building the script " [openjpac] java.lang.IllegalArgumentException: java.lang.ClassNotFoundException: entities.TBLFireResourceDO".
And doing this in RSA 7.0 environment!. looks like build path and everything is correct.
here is the build.xml
<project name="enahnceJPA">
<target name="enhance">
<!-- define the openjpac task; this can be done at the top of the -->
<!-- build.xml file, so it will be available for all targets -->
<taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask" />
<openjpac>
<config propertiesFile="./META-INF/persistence.xml" />
<classpath refid="enh.classpath" />
<fileset dir=".">
<include name="**/entities/*.java" />
</fileset>
</openjpac>
</target>
</project>

BUILD FAILED

...Any idea

[Marc Prud'hommeaux]

Marking as "Invalid" because this is more of a support request (which should be handled on one of the OpenJPA mailing lists).

As to the reported problem, it does sound like OpenJPA cannot actually find the entities.TBLFireResourceDO. Are you sure the "enh.classpath" actually contains the root directory in which entities/TBLFireResourceDO.class resides? If you use the <available> ant task to check this, is the class found?

Please send any follow-ups to the mailing list.

Hi,

I met the same OPENJPA-294 problem. I use the following script.

<project name="enahnceJPA">
<target name="enhance">
  <!-- define the openjpac task; this can be done at the top of the -->
  <!-- build.xml file, so it will be available for all targets -->
  <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask"/>
  <!--taskdef name="openjpac" classpathref="enh.classpath" classname="org.apache.openjpa.ant.PCEnhancerTask"/-->

  <!-- invoke enhancer on all .jdo files below the current directory -->
  <openjpac>
   <config propertiesFile="./META-INF/persistence.xml"/>
   <!--classpath refid="enh.classpath" /-->
    <fileset dir=".">
     <include name="**/com/ibm/persistence/ejb3/order/entity/*.java" />
     <include name="**/com/ibm/persistence/ejb3/order/facade/*.java" />
    </fileset>
  </openjpac>
</target>

</project>

I cannot build the enhanced class even if I use the "enh.classpath".
If you hava any idea, Could you let me know how to solve the problem?

thanks and regards.

Hi,

Is there any solution about OPENJPA-294?
I tried to find the solution, but i cann't.

Best Regards,

SeYoul Park.

[Richmond Stevenson]

Did you ever resolve this? We're having the exact same problem in Rational Software Architect - we've tried adding the WEB-INF/classes directory to the ant task class path with no luck.

Thanks,
Rich

Try adding a path element to where ever your compiled classes end up. In our case, we're building a web application, so we added the following to our build.xml and got it to work. These settings are specific for IBM RAD/RSA, and assume that you've set the base directory of your ant build task to the root of your project.

<classpath>
     <pathelement path="${java.class.path}" />
     <pathelement path="./WebContent/WEB-INF/classes" />
</classpath>

Good luck!

[Matthew Kelm]

SeYoul, the example you were referring to needs the classpath defined as below:

<project name="enahnceJPA">
<target name="enhance">
  <!-- define the openjpac task; this can be done at the top of the -->
  <!-- build.xml file, so it will be available for all targets -->
  <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask"/>

  <!-- invoke enhancer on all .jdo files below the current directory -->
  <openjpac>
   <config propertiesFile="./META-INF/persistence.xml"/>
    <fileset dir=".">
     <include name="**/com/ibm/persistence/ejb3/order/entity/*.java" />
     <include name="**/com/ibm/persistence/ejb3/order/facade/*.java" />
    </fileset>
   <classpath>
   <path location="${basedir}" />
   </classpath>
  </openjpac>
</target>

</project>
