Hi Roshan,
Thanks for helping with the testing of the activemq provider. I'm
going to step through your log and identify where/how it's
diverging from mine for the
ActiveMQServiceRegisterTest.testGetProxy (I think all the test
cases are seeing the same thing, so focusing on this one is
reasonable).
First, the exception that starts with
[log;+0530 2009.05.21
20:41:23:469;ERROR;org.eclipse.ecf;org.eclipse.core.runtime.Status[plugin=org.eclipse.ecf;code=4;message=getSupportedIntents;severity4;exception=java.lang.ArrayStoreException;children=[]]]

at
org.eclipse.ecf.internal.provider.jms.activemq.ActiveMQJMSServerContainerInstantiator.getSupportedIntents(ActiveMQJMSServerContainerInstantiator.java:71)
...
Was a small bug in the getSupportedIntents implementation. It's
now fixed and released to HEAD. So you shouldn't see it again.
This warning:
WARNING: path isn't a valid local location for TcpTransport to use
java.lang.NumberFormatException: For input string: "/exampleTopic"

I've reported to ActiveMQ with this bug:
https://issues.apache.org/activemq/browse/AMQ-2256
It's not fatal, however, as the NumberFormatException is simply
caught and logged as a warning within ActiveMQ. Until ActiveMQ
fixes it I think we're just going to have to live with it.
Now, we get to the main difference. You have this output:

<scott> This indicates that the remote service was registered with
the ActiveMQJMSServerContainer. This is fine/looks correct.

<scott>this indicates that you have received a discovery
notification (good), and that the proxy lookup has begun. But at
this point you then get the failure...as indicated by the TRACE
and the log entry:

<scott> the crucial information here is that
remoteReferences=null...that is, the lookup via
getRemoteServicesReference did not find an remote references. This

<scott> indicates that the remote reference was used to create
proxy and registered in local service registry.
Obviously this is different from what you are seeing...mine is
finding the remote service reference, using it to create the proxy
and registering the proxy. The only important difference in your
output for hostRegistered and
proxyRetrievingRemoteServiceReferences is the presence of the
service property: 'foo=bar' in yours. Are you using the latest
versions of all the test classes/plugins? I don't believe this
should actually make a difference for this problem...but I suppose
it's possible that this is triggering some bug in our code. So I
think the next step is to do these things:
1) Remove the 'foo=bar' property, update all code to latest and
rerun test.
2) turn on tracing in this bundle:
org.eclipse.ecf.provider.remoteservice and rerun this test:
ActiveMQServiceRegisterTest
3) run this junit plugin test also:
org.eclipse.ecf.tests.provider.jms.activemq.remoteservice.ActiveMQRemoteServiceTest
and see if it produces similar failures. Hopefully it will, but
either way it will be informative.
Thanksinadvance,
Scott
