NotSerializableException exception on WorkManager

feijtel Dec 15, 2010 10:01 AM

Hello,

I'm trying to port an application running on JBoss 4.04 to JBoss 6 CR1.

So far this has been going quite well. The few issues that I ran into were easily solved. But today I ran into a problem which I haven't been able to resolve.

The application makes use of a WorkManager to delegate tasks to. But during deployment, when the WorkManager is resolved, I get an exception.

This is the code that is being executed (the workMember variable is a class member):

try {
   Context jndiContext = new InitialContext();
   MBeanServerConnection mconn = (MBeanServerConnection) jndiContext.lookup("jmx/invoker/RMIAdaptor");
   ObjectName objectName = new ObjectName("jboss.jca:service=WorkManager");

JBossWorkManagerMBean jwm = (JBossWorkManagerMBean)

MBeanServerInvocationHandler.newProxyInstance(mconn,objectName, JBossWorkManagerMBean.class, false)

workManager = jwm.getInstance();

} catch(Exception e) {

...

}

I am not very familiar with JMX or the WorkManager. Can anyone point me in the right direction on how to solve this issue?

Any help would be greatly appreciated.

Thanks!

I think I've found a solution myself, searching through various websites.

In de code sample I provided, I used a jndi lookup. When replaced by MBeanServerLocator.locateJBoss(), the code runs fine. This obviously because serialization isn't needed anymore now that I do not use the RMIAdaptor anymore.

Hope this helps others. The work code sample is:
MBeanServer mconn = MBeanServerLocator.locateJBoss(); ObjectName objectName = new ObjectName("jboss.jca:service=WorkManager"); JBossWorkManagerMBean jwm = (JBossWorkManagerMBean) MBeanServerInvocationHandler.newProxyInstance(mconn,objectName,JBossWorkManagerMBean.class,false); workmanager = jwm.getInstance();

2. NotSerializableException exception on WorkManager

hostalp Jan 10, 2011 7:21 AM (in response to feijtel)

Hi,
we seem to have bumped into the same problem when using Spring (3.0.5) bean org.springframework.jca.work.jboss.JBossWorkManagerTaskExecutor for accessing the work manager where pretty much the same (JNDI) approach is applied.

The question of interest is whether the current state in JBoss 6 is intended or not - so which code has to be changed to fix this - Spring or JBoss?
Note that the above mentioned "fix" also introduces a direct dependency on JBoss code which might be not that good thing for a framework such as Spring.

hostalp Jan 17, 2011 5:55 AM (in response to hostalp)

Spring's (3.0.5) org.springframework.jca.work.jboss.JBossWorkManagerUtils uses the following code:

{code}private static final String JBOSS_WORK_MANAGER_MBEAN_CLASS_NAME = "org.jboss.resource.work.JBossWorkManagerMBean";
private static final String MBEAN_SERVER_CONNECTION_JNDI_NAME = "jmx/invoker/RMIAdaptor";
...
   Class<?> mbeanClass = JBossWorkManagerUtils.class.getClassLoader().loadClass(JBOSS_WORK_MANAGER_MBEAN_CLASS_NAME);
   InitialContext jndiContext = new InitialContext();
   MBeanServerConnection mconn = (MBeanServerConnection) jndiContext.lookup(MBEAN_SERVER_CONNECTION_JNDI_NAME);
   ObjectName objectName = ObjectName.getInstance(mbeanName);
   Object workManagerMBean = MBeanServerInvocationHandler.newProxyInstance(mconn, objectName, mbeanClass, false);
   Method getInstanceMethod = workManagerMBean.getClass().getMethod("getInstance");
   return (WorkManager) getInstanceMethod.invoke(workManagerMBean);{code}

which we then changed into something like:

{code}import org.jboss.mx.util.MBeanServerLocator;
...
private static final String JBOSS_WORK_MANAGER_MBEAN_CLASS_NAME = "org.jboss.resource.work.JBossWorkManagerMBean";
...
   Class<?> mbeanClass = JBossWorkManagerUtils.class.getClassLoader().loadClass(JBOSS_WORK_MANAGER_MBEAN_CLASS_NAME);
   MBeanServer mconn = MBeanServerLocator.locateJBoss();
   ObjectName objectName = ObjectName.getInstance(mbeanName);
   Object workManagerMBean = MBeanServerInvocationHandler.newProxyInstance(mconn, objectName, mbeanClass, false);
   Method getInstanceMethod = workManagerMBean.getClass().getMethod("getInstance");
   return (WorkManager) getInstanceMethod.invoke(workManagerMBean);{code}

but this of course introduces a dependency on the JBoss code from within the Spring code and thus we don't think this is the "correct" solution.

Is there any proposal on anything which wouldn't require that dependency while still maintaining the functionality?

If not then we think the JBoss code will have to be changed to let it working via the JNDI approach.
