Hi all,
I'm using jboss jbpm 3.2.2. using graphical tool created my application in
which I want embed an action on a particular event/ transition. when that
action class is invoked I get this exception :
Error signalling token: An exception of type
"org.jbpm.graph.def.DelegationException" was thrown.
-------processdefinition.xml-----------
<process-definition xmlns="" name="Hello2">
<start-state name="start">
</start-state>
<task-node name="process">
</task-node>
<task-node name="show sum">
</task-node>
<end-state name="end"></end-state>
</process-definition>
--------------------------------------------------------
MyAction is available in the same package as that of processDefinition.xml
MyAction.java
_______________
import org.jbpm.context.exe.ContextInstance;
import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.graph.exe.ProcessInstance;
public class MyAction implements ActionHandler {
private static final long serialVersionUID = 1L;
public void execute(ExecutionContext executionContext) throws
Exception {
// TODO Auto-generated method stub
ProcessDefinition processDefinition =
ProcessDefinition.parseXmlString("processdefinition.xml");
ProcessInstance processInstance = new
ProcessInstance(processDefinition);
ContextInstance contextInstance =
processInstance.getContextInstance();
String getnum1 = (String)contextInstance.getVariable("num1");
String getnum2 = (String) contextInstance.getVariable("num2");
String sum = getnum1 + getnum2;
contextInstance.setVariable("sum",sum);
}
}
