In my web app I call a servlet. This servlet in turn instantiates a simple
class. That class initially does this to verify I have access to the
NXRuntime.
RuntimeService rs = NXRuntime.getRuntime();
This part seems to work just fine. But when I use a nearly verbatim example
from the documentation for getting an instance of a custom component.
adm = (Adm)
NXRuntime.getRuntime().getComponent("com.anystream.velocity.adm.Adm");
I want to execute a simple method within that component after I actually get it
instantiated from the other jar file. The NXRuntime is evidently not seeing my
other components/extensions despite having been registered....or I have the
war configured incorrectly for a web app to use the component.
"com.anystream.velocity.adm.Adm");

The actual errors returned are:

part of the call)

It now fails. So the problem is actually getting that component
instance....not access to the NXRuntime.
Previously I had seen a message that the war was registered / resolved:
22:59:59,828 INFO [OSGiAdapter] Installing OSGi bundle:
file:/C:/jboss/server/default/tmp/deploy/tmp31801SimpleEar.ear-contents/SimpleWar.war
22:59:59,828 INFO [BundleRegistry] Registering resolved bundle:
com.anystream.velocity.test.war
But I never get a message like "COMPONENT_REGISTERED" for the war. (Despite
receiving that for an extension inside of the war for the same custom
component.) I am modeling the ability to add plugins into an app to expose
xslt & scripting files as needed for customizations on a client by client basis.

I hope this helps. I'm definately a rat running in circles at this point.
(Maybe it's the lack of sleep....dunno.)
Thanks!
