Hi,
I have a small processdefinition which calls a ActionHandler when entering a
transition:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2"
name="TransportProcessDef">
| <start-state name="start">
| <transition name="" to="state1">
| <action class="com.xxx.man.MyAction" name="Doing some complex
things"></action>
| </transition>
| </start-state>
| <state name="state1">
| <transition name="toEnd1" to="end1"></transition>
| </state>
| <end-state name="end1"></end-state>
| </process-definition>
|
When I run the process, I get the following exception:
anonymous wrote : ERROR [org.jbpm.instantiation.Delegation] couldn't
instantiate delegation class 'com.ptvag.jabba.tourmgmt.MyAction'
| java.lang.NullPointerException...
I don't understand this behaviour, because I can instantiate an object of the
Class MyAction with a Classloader without any problem:
| Class clazz = c.loadClass("com.xxx.man.MyAction");
| MyAction a = (MyAction) clazz.newInstance();
| a.execute(null);
|
Can anybody help me with this problem? Thanks in advance!
Regards,
TMK
