[jboss-user] [JBoss jBPM] - customTaskInstance example failing with error

[rossputin]

Hi guys,

I tried to run 'ant test' in /jbpm-jpdl-3.2.1/examples/customTaskInstance today, and the same in 3.2.2, first of all it failed to compile, the 'compile.test' target seems to be failing, unless there is some config I need to do first.

Anyhow, after some tweaking of example.base.build.xml to make it work... see...


  |   <target name="create.manifest">
  |     <mkdir dir="target/META-INF" />
  |     <manifest file="target/META-INF/MANIFEST.MF">
  |       <attribute name="Implementation-Title" value="jBPM Core Library"/>
  |       <attribute name="Implementation-Version" value="${lib.jbpm.jpdl.version} (date:${now})"/>
  |       <attribute name="Implementation-URL" value="http://www.jboss.org/"/>
  |       <attribute name="Implementation-Vendor" value="JBoss Inc."/>
  |       <attribute name="Implementation-Vendor-Id" value="http://www.jboss.org/"/>
  |     </manifest>
  |   </target>
  |   
  |   <target name="package.jar" depends="compile, create.manifest">
  |     <jar jarfile="target/jbpm-custom-task.jar" manifest="target/META-INF/MANIFEST.MF">
  |       <fileset dir="target/classes" />
  |     </jar>
  |   </target>
  | 

I got the test running... but then it bombed out with the following error...

I left the hibernate.cfg.xml and jbpm.cfg.xml files untouched.

Possibly I was running the ant targets from the wrong place, or I forgot to configure something?

Anyhow, any help is greatly appreciated,

regards
