[JBoss AS7 Development] - Bootdelegation and Jaxb

"Bootdelegation and Jaxb"

--------------------------------------------------------------
Hello Folks
I am deploying a OSGI bundle in Jboss AS 7. This Bundles uses JAXB . This bundle alos exposes JAXRS services using CXF DOSGI. So I have also deployed CXF DOSGI bundle .
My problem is when my bundle try to initialize the JAXB context , it throws a class cast exception . Further debugging revealed that JAXBConext is using BundleClassLoader to load the Context factory .
com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to javax.xml.bind.JAXBContext
To avoid this conflict , I am trying to get my bundle to load JAXB either from Jboss AS7 or from the JDK 1.6 .
I read some article that I can use bootdelegation and specify some packages ao that All these packages will be loaded by parent class loader .
I tried setting bootdelegation for javax.xml.bind.context and for com.sun.* but there is no change in behavior .
I am setting using -Dorg.osgi.framework.bootdelegation=sun.*,com.sun.*,javax.*
I have also tried setting *org.osgi.framework.system.packages.extra in server configuration , but that doesn't help either.
*
Has anyone used this before ?
Can someone share thoughts if I am on right track ?
Is there any other way to resolve this issue ?
Appreciate any insights.
Sunil

}
}
In the documentation( https://docs.jboss.org/author/display/AS7/Order+Application+Migration+fro... https://docs.jboss.org/author/display/AS7/Order+Application+Migration+fro... )
In addition to the change to injection, which was supported in EAP 5.1.0, the lookup name changed from:
OrderManagerApp/DistributionCenterManagerBean/local
to:
java:app/OrderManagerEJB/DistributionCenterManagerBean!services.ejb.DistributionCenterManager
any help will be apprecite.
thanks!

[jBPM Development] - JBPM5 - Human task not getting completed

"JBPM5 - Human task not getting completed"
To view the discussion, visit: http://community.jboss.org/message/610723#610723
--------------------------------------------------------------
I am trying out a sample process with a human task. Configured persistence for both Task server and process instnace in postgresql. Process flow is stopping at the human task as expected. After this I am completing the task using a human task client. Problem is that after this the process is not proceeding to complete. I am using JPAKnowledgeService and CommandBasedWSHumanTaskHandler. Is there anything additional need to be done for completing the process another than invoking the task api at task server ?
Is there any significance to the task name & name we give to the Human Task in the process ?
Code used for starting process.
Logger logger = Logger.getLogger(this.getClass().getName());
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());
logger.info("Loading process definition");
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(processDefinition), ResourceType.BPMN2);
kbase = kbuilder.newKnowledgeBase();
Properties properties = new Properties();
properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");
properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory");
KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);
logger.info("create session");
ksession = JPAKnowledgeService.newStatefulKnowledgeSession( kbase, config, env );
int sessionId = ksession.getId();
logger.info("Session Id : "+sessionId);
logger.info("Registering Human Task listener");
CommandBasedWSHumanTaskHandler cbHandler = new CommandBasedWSHumanTaskHandler(ksession);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", cbHandler);
ksession.startProcess("com.ht.test");
Human Task Service
public class HumanTaskService {
private TaskService taskService = null;
private TaskServiceSession taskSession = null;
public HumanTaskService(EntityManagerFactory emFactory) {
Logger logger = Logger.getLogger(this.getClass().getName());
logger.info("Initializing Human Task Service");
SystemEventListener systemEventListener = SystemEventListenerFactory.getSystemEventListener();
taskService = new TaskService(emFactory, systemEventListener);
taskSession = taskService.createSession();
taskSession.addUser(new User("Administrator"));
}
public void addUser(String userId) {
Logger logger = Logger.getLogger(this.getClass().getName());
logger.info("Adding user "+userId);
taskSession.addUser(new User(userId));
}
public void startTaskService() {
Logger logger = Logger.getLogger(this.getClass().getName());
logger.info("Starting Human Task Service");
MinaTaskServer server = new MinaTaskServer( taskService );
Thread thread = new Thread( server );
thread.start();
}

I must admit I don't really know a lot about JBoss, but I am migrating an application from JBoss 6 to 7.
Now I get this error when I try to login:

What could be the reason for this error?
