--------------------------------------------------------------
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">

<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.

probably because this is where the signa() method is defined,
do you think this is a problem?
> -Can custom node class implement only ExternalActivityBehaviour??
it's java - you can implement as many interfaces as you want with your class
> -How can custom nodes be used to create new user nodes??
it's ment to implement new behaviour by the users of the API, but you still use the "custom" tag for it in your process definition
> -is there any way 2 add new attributes for custom nodes??
I don't see a way to add attributes in the "custom" tag but you can set attributes in your implementation (java class) , see the user guide section 6.7.1

Getting thread dump on jboss
by Unmesh joshi
Hi,
We have jboss running in a cluster (two nodes). If I give kill -3 <pid> command, it does not give me thread dump in server.log file.I can get thread dump through ServerInfo jmx bean. Anyone knows why we dont get it in server.log (which I presume is where System.out is directed)
Thanks,Unmesh
