[jboss-user] [jBPM] - Different ClassLoader, ClassCastException

Konrad Schuler [http://community.jboss.org/people/pseudoJBoss] created the discussion "Different ClassLoader, ClassCastException" To view the discussion, visit: http://community.jboss.org/message/535208#535208 -------------------------------------------------------------- Hi, 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 pe.getExecutionService().getVariable(executionId, "customer")   is BaseClassLoader@c94114{vfsfile:/C:/Programms/jboss-5.1.0.GA/server/default/conf/jboss-service.xml} and the ClassLoader of Customer customer...   is BaseClassLoader@12e43f8{vfsfile:/C:/Programms/jboss-5.1.0.GA/server/default/deploy/MyWebApp.war/} So what can I do to solve the problem. Thank you!!! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/535208#535208] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
