Hi I have written the following code: ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( | "<process-definition> " + | " <start-state name='start'>" + | " <transition to='mailnode1' name='to_mailnode'></transition>" + | " </start-state> " + | " <mail-node name='mailnode1' to='<email address>' >" + | " <subject>a</subject> " + | " <text>This is regarding</text>" + | " <transition to='end' name='to_end'></transition> " + | " </mail-node> " + | "<end-state name='end'></end-state>" + | "</process-definition>"); | | | ProcessInstance processInstance = new ProcessInstance(processDefinition); However, the above code gives a warning on parsing: 13:23:38,166 WARN [JpdlXmlReader] process xml warning: transition to='mailnode1 ' on node 'start' cannot be resolved On signalling the start node, I get the runtime exception: org.jbpm.JbpmException: transition 'to_mailnode' doesn't have destination. check your processdefinition.xml Please let me know what is going wrong.
