by btl_ayd
Hi
I want o call websale process that deploying on he server of jpm database.
I found some code about it on this forums.But when execute this code the error has been occured.
here is code for starting process:
| public static void startProcessDefinition() {
| String processDefinitionName = new String("websale");
| JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| GraphSession graphSession = jbpmContext.getGraphSession();
| ProcessDefinition definition = graphSession.findLatestProcessDefinition(processDefinitionName);
| ProcessInstance instance = definition.createProcessInstance();
| instance.signal();
| jbpmContext.save(instance);
| } finally {
| jbpmContext.close();
| }
| }
|
error has beeb occured

injecting Spring beans into action handlers
by Matthias Pretzer
Dear all,
I'd like to use beans from my existing Spring context inside my
ActionHandler. I'm aware of Spring's JbpmHandlerProxy ActionHandler.
However, that won't allow me to set properties of my ActionHandler
implementation from within the process definition.
What I'd like to have is some kind of combination of a jbpm-configured
ActionHandler and a spring-configured one. I think that's only possible,
if the action handler is configured by jbpm and delegates some logic to
a spring bean.
Does anyone know, how to do this?
best regards,
Matthias
