NXRuntime Demo

Hi,

I'm trying to get the Runtime demo at https://svn.nuxeo.org/nuxeo/demo/NXRuntime running, but i happend to have some problems and the documentation didn't really help. Hope someone here has some answerrs.

First of all: the HelloWorldComponent implements Component which has to override the methods activate(ComponentContext context) and deactivate(ComponentContext context), which are never used. In opposite to the ones with the RuntimeContext as Parameter... But I included both so this works, even if it seems strange to me, but it works somehow.

Now I have two real problems:

Object[] messages = extension.getContributions(); does lead to an empty array and i never get to the loop:

        for (Object message : messages) {
            HelloMessage msg = (HelloMessage)message;
            this.messages.add(msg);
            System.out.println("Registering message: " + msg.getMessage());
        }

since it is empty and no extension can be registered.

Both the component and the HelloWorldextension of HelloWorld are registred as components are activated correctly. I just can't acces the contributions thus the real extension and I don't understand why.

Second Problem is the access from outside:

In the HelloWorldService:

HelloComponent hc = (HelloComponent)NXRuntime.getRuntime()
.getComponent("org.nuxeo.runtime.demo.HelloComponent");

I can't used this, because NXRuntime is deprecated, ok so i read, that i have to use Framework.getRuntime(). instead. But this only gives me a null Pointer Exception so I can't access the components when i'm not inside the RuntimeContext...

I am running Jboss 4.05 with the NXRuntime.sar deployed. The only corrections i made to the original example involed the two necessary methods in HelloComponent due to its abstract superclass Component and I changed the NXRuntime to Framwork inside the Jboss Demo.

That's it.

Hope you can find some time to help me with these issues.

Cheers,

Krys
