Hello,
I have a problem running a deployed Jbpm process that fires some Drools rules in an
ActionHandler. When testing the process through the Jbpm API, it runs perfectly fine,
though.
Unfortunately I could not find a helping hint for this issue on this forum or google.
The part of the Jpdl processs where the ActionHandler is invoked looks as follows:
| <task-node name="Receive Return">
| <task name="Receive Item" swimlane="Shipping">
| <controller>
| <variable name="tracking number"
access="read"></variable>
| <variable name="number"
access="read,write,required"></variable>
| </controller>
| </task>
| <event type="node-leave">
| <action name="Execute Shipping Rules"
class="com.sample.action.FireRulesActionHandler">
| <rulefile>Sample.drl</rulefile>
| </action>
| </event>
| <transition name="" to="node1">
| </transition>
| </task-node>
|
As I said, when I execute the process through the Jbpm API, the process executes just
fine, including the FireRulesActionHandler which fires all rules as it is supposed to. But
when deploying the project to the server, it will deploy it, but during execution of the
process, it would stop executing at that point where the ActionHandler is called. The
server log looks as follows:

I guess the line anonymous wrote : Caused by: java.lang.NoClassDefFoundError:
org/drools/RuleBase
is the essential one. Probably it's a problem concerning jar - files. But
unfortunately I don't know which jar files are missing and how to include the missing
jar files then. I am using the Jbpm server that came with the
"jbpm-starters-kit-3.1.3".
I appreciate any hint that could help me to solve this problem. Many thanks in advance!
Best regards,
Maurice
