I think the use of the factory element here is also pretty cool. The one thing that strikes me is that the bean with the factory element is defined with a single interface class, even though the proxy will, in fact, implement two interfaces. I certainly don't know the microcontainer internals, but superficially it seems like a bean with a factory element could live without a class attribute, since it could be derived from the factory method's return type.

[Design of POJO Server] - Re: CNFE when using PojiProxy/Remoting

by ALRubinger

I'm glad you replied, Anil, because this issue is regressing every single last one of the security tests for EJB3. :) What I don't understand is why EJB3 Proxy replacing the old mechanism would cause this to fail.

Something to do with classes and jar packaging. The interface is not available that RMI is trying to download.

The best tool for "do exactly once" types of tasks that I've found is AtomicBoolean: | private final AtmoicBoolean freed = new AtomicBoolean(false); | | // ...then later, in your idempotent free() method: | if (! freed.getAndSet(true)) { | doTheOneTimeTask(); | } | Of course that's JDK5+ only, so it might not be suitable for things that have to run on older JDKs.

Further classes that can go from jboss-remoting-aspects into a new remoting (integration?) project: PojiProxy Remoting AOPRemotingInvocationHandler ...as these really have nothing to do with aspects. I'm in no rush to move these now, as it'll probably wreak havoc on existing users of this code (lord knows where this stuff is peppered; they used to be in AS). Only thing we get by moving it out is an organizational benefit.

[Design of POJO Server] - CNFE when using PojiProxy/Remoting

by ALRubinger

In integrating EJB3 Proxy w/ EJB3 Core I'm occasionally coming across a CNFE when making a remote invocation from the client to the Container. // Create a POJI Proxy to the Container | Interceptor[] interceptors = | {IsLocalProxyFactoryInterceptor.singleton, InvokeRemoteInterceptor.singleton}; | PojiProxy handler = new PojiProxy(this.getContainerName(), locator, interceptors); | Class<?>[] interfaces = new Class<?>[] | {InvokableContext.class}; | InvokableContext<? extends ContainerMethodInvocation> container = (InvokableContext<?>) Proxy.newProxyInstance( | interfaces[0].getClassLoader(), interfaces, handler); | ... | | // Invoke | Object result = container.invoke(proxy, invokedMethod, args); | Exception received is below.
