Hi I treid it but it didnt work.I want to start this process in java class.
I changed "JbpmConfiguration jbpmConfiguration =JbpmConfiguration.getInstance(); " as a "JbpmConfiguration jbpmConfiguration =JbpmConfiguration.parseResource("jbpm.cfg.xml");"
and here is my all code that calling process:
| public static void startProcessDefinition() {
| String processDefinitionName = new String("websale");
| JbpmConfiguration jbpmConfiguration =JbpmConfiguration.parseResource("jbpm.cfg.xml");
|
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| GraphSession graphSession = jbpmContext.getGraphSession();
| ProcessDefinition definition = graphSession.findLatestProcessDefinition(processDefinitionName);
| System.out.println(graphSession.getProcessDefinition(2));
| ProcessInstance instance = definition.createProcessInstance();
| instance.signal();
|
| jbpmContext.save(instance);
| } finally {
| jbpmContext.close();
| }
| }
| public static void main(String[] args) {
|
| uzak.startProcessDefinition();
| }
|
here is error has been occured

here is my jbpm.cfg.xml:
<jbpm-configuration>

| <!--
| This configuration is used when there is no jbpm.cfg.xml file found in the
| root of the classpath. It is a very basic configuration without persistence
| and message services. Only the authorization service installed.
| You can parse and create processes, but when you try to use one of the
| unavailable services, you'll get an exception.
