Hi Scott,
All the test cases are working for me now. I have done a cvs update and now the test packages are getting executed without assertion errors. Thanks once again for helping me with the test cases. But when I compare the results with what I have on my console with that of yours, still I get the remote interface as different. 
e.g:
<mine>
 hostRegistered
 serviceReference=*org.eclipse.ecf.tests.osgi.services.distribution.TestServiceInterface1*}
Do you think still I have an old code base?
The TestServiceInterface1 and 2 classes are used for the ServicePublication tests...so you should see some tests with this service interface and others with the IConcatService service interface. 



Though all test cases are getting executed succesfully...
WIth respect to the test cases for activemq what I see is you are creating an ActiveMQJMSServerContainer then registering the remote services. Does the container type name makes any difference? In the test case I see it as 'ecf.jms.activemq.tcp.server' but the ECF documentation talks about the conatiner name as 'ecf.jms.activemq.tcp.manager'.
I suppose the container type should probably be ecf.jms.activemq.tcp.manager...not only to match the documentation, but that is what it is :). Please open a bug to that effect and I will make the necessary change to the the activemq plugin.xml (and test code).
Do we have to use IRemoteAdapters for making this test case work? Also the listeners are registered initially before running the test case. Are they essential for testing using the RFC 119 transaparent way of accessing remote service?
No. They are there to aid in debugging..and to test the use of the listeners registered in the service registry. 

Thanks,

Scott
I am not sure whether the questions I have added make sense or not? but looking forward to your response. Thanks again for aptiently answering my queries... Regards 
Roshan

    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"

    at java.lang.Integer.parseInt(Unknown Source)
    at
    org.apache.activemq.transport.tcp.TcpTransportFactory.createTransport(TcpTransportFactory.java:125)
    ...

    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:


    hostRegistered
    serviceReference={org.eclipse.ecf.tests.osgi.services.distribution.TestServiceInterface1}={osgi.remote.interfaces=[*],
    foo=bar, ecf.rsvc.cid=JMSID[tcp://localhost:61616/exampleTopic],
    service.id=120}
    remoteServiceContainer=RemoteServiceContainer
    [containerID=JMSID[tcp://localhost:61616/exampleTopic],
    container=org.eclipse.ecf.provider.jms.activemq.container.ActiveMQJMSServerContainer@1ce08c7,
    containerAdapter=org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject@27de24]

    foo=bar}]

    <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

    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
