first, something to the background.
I try to run a simple BPMN 2.0 Process on jbpm-4.4-SNAPSHOT, where the user tasks can be handled by a Portlet (JSF, Facelets) on Liferay 5.2.3. The AS is JBoss 5.1.
The deployment of the Process I do as follows
ProcessEngine pe=new Configuration().buildProcessEngine(); RepositoryService repositoryService = pe.getRepositoryService(); NewDeployment deployment = repositoryService.createDeployment(); deployment.addResourceFromClasspath("myprocess.bpmn.xml"); deployment.deploy();
and it works fine.
Than I start the process as follows
Customer customer=new Customer("Firstname", "Lastname"); Map<String, Object> variables = new HashMap<String, Object>(); variables.put("customer", customer); ProcessInstance pi = pe.getExecutionService().startProcessInstanceByKey("myprocess", variables);
and it also works fine.
Than in a JSF Bean I wand to read the "customer" variable to handle a user task. So I do the following.
String executionId=pe.getTaskService().getTask(currentTaskId).getExecutionId(); Customer customer=(Customer)pe.getExecutionService().getVariable(executionId, "customer");
And here I have a problem.
If the com.mycomp.Customer class is within my .war than there is a ClassNotFoundException .. com.mycomp.Customer...
If I put the com.mycomp.Customer class to the JBoss (global) libs, than there is a ClassCastException ... can not cast com.mycomp.Customer to com.mycomp.Customer ...
- I am sure that there is only one com.mycomp.Customer class within my JBoss
- And the com.mycomp.Customer class implements Serializable with a generated serial version id
I think the problem is the different ClassLoader. After debugging I've found out that the ClassLoader of the class of
and the ClassLoader of
So what can I do to solve the problem.
