    customTaskInstance example failing with error

    Ross McDonald Novice

      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
