--------------------------------------------------------------
I'm having an issue with one specific process deploying it on an oracle db. In total I've around 20 business process definitions. When the one specific process is included, I can not start any process execution. Not even an execution that has nothing to do with it. Also when going to the jBPM console I can not see the process definitions.

My configuration:
- jBPM 4.3
- Oracle driver: 10.2.0.1.0
- Using the ant task to deploy: org.jbpm.pvm.internal.ant.JbpmDeployTask

The process definition that is giving the problems:


<?xml version="1.0" encoding="UTF-8"?>

<process xmlns="http://jbpm.org/4.0/jpdl" name="notifySigningFinished">

   <start name="start1" g="21,233,48,48"><transition to="getBundle"/></start>

   <!-- Check if bundle is both signed -->

   <java ejb-jndi-name="SignatureProcessBean/local" method="getBundle" name="getBundle" var="bundle" g="200,162,92,48">

      <arg><object expr="#{bundleId}"/></arg>

      <transition to="isSigned" g="-39,-21"/>

   </java>

   <decision name="isSigned" g="316,162,48,48">

     <transition name="to bundle is signed" to="fetchBundleInfo" g="-128,-22">

           <condition expr="#{bundle.signStatus eq 'BOTH_SIGNED'}" />

      </transition> 

      <transition name="to end" to="end" g="-3,-22"/>

   </decision>

   <java ejb-jndi-name="SignatureProcessBean/local" g="516,162,92,48" method="getBundleInfo" name="fetchBundleInfo" var="bundleInfo">

      <arg>

      <object expr="#{bundleId}"/>

      </arg>

      <transition to="fetchMailToList"/>

   </java>

   <java ejb-jndi-name="SignatureProcessBean/local" g="650,162,92,48" method="getMailToAPLList" name="fetchMailToList" var="mailToAPLList">

      <transition to="bundle is signed"/>

   </java> 

    <state name="bundle is signed" g="650,265,48,48">

       <transition name="end" to="end" />

   <transition name="timeout" to="sendBundleSignedNotification">

      <timer duedate="1 business seconds" />

    </transition> 

  </state>

  <sub-process g="750,265,92,52" name="sendBundleSignedNotification" sub-process-key="sendBundleSignedMail">

             <parameter-in subvar="mailToAPLList" var="mailToAPLList"/>

             <parameter-in subvar="bundleInfo" var="bundleInfo"/>

<transition to="end"/>

   </sub-process>

   <end name="end" />

</process>





The exception I'm getting when starting a process execution:

When deploying it on a local mySQL, I've no problems.

Some additional remarks: I've had similar problems with oracle in the past (deploying jBPM business processes). I could fix them by removing all xml comments from the jpdl files and also any DOS line feeds. When doing a google search on this issue, I can find one related post ( http://permalink.gmane.org/gmane.comp.java.jboss.user/293637 http://permalink.gmane.org/gmane.comp.java.jboss.user/293637), but I can not find back that message in the user forums, so no idea if there's a solution for this.
