15. Re: Nukes compatibility to JBoss upgrade path

invisiblemage Aug 11, 2004 9:36 AM (in response to kamikatze)

ok, had some time today to have a look again...

The getNext() is now done in the AbstractInterceptor.Invoke()...
so I just deleted all the lines in the LifecycleInterceptor.

Some strange things happen now and then wenn in the LifeCycle the invoke() is called with type "invoke"... debug showed that "invoke, getLanguage" is called on the MBeanAttributeInterceptor, which then throws an Exception because it does not understand the command.
I just catched this exception and returned null in LifeCycle.invoke. It should not be done this way, but now nukes deploys, at least...

Next problem ist a nullpointer:

has any further work gone into this? i've given this a go myself, and i keep getting the following error trying to deploy:

i don't understand why it would be reported that the Theme interface is not visible via the class loader.

my current thought is that something isn't right in the LifeCycleInterceptor, but i'm not really sure what that would be.

this is what i've done w/ the class:

public class LifeCycleInterceptor
 extends AbstractInterceptor
{

 public LifeCycleInterceptor() {
 super("LifeCycle Interceptor");
 this.log = Logger.getLogger(this.getClass().getName());

 log.debug("no args life cycle interceptor");
 }

 //private MBeanInvoker invoker;
 private MBeanInfo info;

 // Attributes ----------------------------------------------------

 private Logger log;

 // Constructors --------------------------------------------------

 public LifeCycleInterceptor(MBeanInfo info, MBeanInvoker invoker)
 {
 //super(info, invoker);
 //this.invoker = invoker;
 this.info = info;
 this.log = Logger.getLogger(invoker.getResource().getClass());
 log.debug("constructor w/ args");
 }

 // Public --------------------------------------------------------

 public Object invoke(Invocation invocation) throws InvocationException
 {
 try
 {
 if (invocation.getType() == InvocationContext.OP_INVOKE &&
 invocation.getSignature() != null &&
 invocation.getSignature().length == 0)
 {
 if ("create".equals(invocation.getName()))
 {
 log.info("Creating");
 create(invocation);
 log.info("Created");
 return null;
 }
 else if ("start".equals(invocation.getName()))
 {
 log.info("Starting");
 start(invocation);
 log.info("Started");
 return null;
 }
 else if ("stop".equals(invocation.getName()))
 {
 log.info("Stopping");
 stop(invocation);
 log.info("Stopped");
 return null;
 }
 else if ("destroy".equals(invocation.getName()))
 {
 log.info("Destroying");
 destroy(invocation);
 log.info("Destroyed");
 return null;
 }
 }
 }
 catch (InvocationException e)
 {
 throw e;
 }
 catch (Exception e)
 {
 // dirty
 throw new InvocationException(e);
 }
 return invocation.nextInterceptor().invoke(invocation);
 }

 // Private -------------------------------------------------------

 private void setState(int nextState, MBeanInvoker invoker) throws Exception
 {
 // if state changes
 if (getState(invoker) != nextState)
 {
 try
 {
 // update the state
 invoker.setAttribute(new Attribute("State", new Integer(nextState)));
 }
 catch (MBeanException e)
 {
 log.error("Cannot send state changed notification", e);
 }
 }
 }

 private int getState(MBeanInvoker invoker) throws Exception
 {
 return ((Integer) invoker.getAttribute("State")).intValue();
 }

 private void create(Invocation invocation) throws Exception
 {
 invocation.nextInterceptor().invoke(invocation);
 setState(ServiceMBean.CREATED, invocation.getInvoker());
 }

 private void start(Invocation invocation) throws Exception
 {
 int state = getState(invocation.getInvoker());
 if (state == ServiceMBean.STARTING || state == ServiceMBean.STARTED)
 {
 return;
 }
 setState(ServiceMBean.STARTING, invocation.getInvoker());
 transition(invocation, ServiceMBean.STARTED, ServiceMBean.FAILED);
 }

 private void stop(Invocation invocation) throws Exception
 {
 if (getState(invocation.getInvoker()) != ServiceMBean.STARTED)
 {
 return;
 }
 setState(ServiceMBean.STOPPING, invocation.getInvoker());
 transition(invocation, ServiceMBean.STOPPED, ServiceMBean.FAILED);
 }

 private void destroy(Invocation invocation) throws Exception
 {
 int state = getState(invocation.getInvoker());
 if (state == ServiceMBean.DESTROYED)
 {
 return;
 }
 if (state == ServiceMBean.STOPPED)
 {
 invocation.getInvoker().invoke("stop", new Object[0], new String[0]);
 }
 try
 {
 invocation.nextInterceptor().invoke(invocation);
 }
 finally
 {
 setState(ServiceMBean.DESTROYED, invocation.getInvoker());
 }
 }

 private void transition(Invocation invocation, int success, int failure) throws Exception
 {
 try
 {
 invocation.nextInterceptor().invoke(invocation);
 setState(success, invocation.getInvoker());
 }
 catch (InvocationException e)
 {
 setState(failure, invocation.getInvoker());
 throw e;
 }
 }
}

any ideas?
