Creating ProcessInstance Object from webapplication

[ganesh7582]

hi,

I persisted processdefinition.xml in to the database, and able to load it from database from my web application, using this code :

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
try {

GraphSession graphSession = jbpmContext.getGraphSession();
ProcessDefinition processDefinition =
graphSession.findLatestProcessDefinition("simple1");
ProcessInstance processInstance = new ProcessInstance(processDefinition);
Token token = processInstance.getRootToken();
token.signal();

but problem is when i am calling token.signal() it is giving an exception
" couldn't load delegation class 'org.gss.jbpm.MessageActionHandler' "
java.lang.ClassNotFoundException: class 'org.gss.jbpm.MessageActionHandler' could not be found by the process classloader

I am unable to call ActionHandler class which is configured in my processdefinition.xml

can any body help me

Are you sure that the action handler is in the deployed archive?
