First iteration of POJO/AOP remoting is here. It uses the new JBoss
Remoting framework
You can remote any object instance of any class. I'll write some real doco
later, but here's the basics:
{
POJO remote = new POJO("hello");
Dispatcher.singleton.registerTarget("myobj", remote);
POJO proxy = (POJO)Remoting.createRemoteProxy("myobj", remote.getClass(),
new InvokerLocator("socket://xeon:5150"));
}
That's it.
There's a few requirements
1. You must have an empty/default constructor defined in the Class of your
object.
2. Invocations on remote methods or fields must be Serializable.
Things to know?
1. You cannot invoke remotely on fields unless the client is a JBoss
instance that has AOP instrumented the class you have remoted.
How to use it? I'll write up better documentation later, but, there's an
example in:
testsuite/src/main/org/jboss/test/aop/bean/RemotingTester.java
testsuite/src/main/org/jboss/test/aop/test/RemotingUnitTestCase.java
testsuite/src/resources/aop/META-INF/jboss-service.xml
How does it work?
I've implemented some code that uses Javassist to generate a proxy class of
a given Class. It inherits from the given class and implements every public
method of that class. The implemented method does interceptor chains and
such. The proxy class implement java.io.Externalizable so that it can be
marshalled across the wire and such. Remoting.createRemoteProxy calls the
class proxy generator and inserts simple simple instance interceptors to
handle the remoting.
FYI, the JBoss Remoting framework rocks. Its easy to set up and it handles
everything for us.
