Re: [ecf-dev] Re: ecf-dev Digest, Vol 45, Issue 35
|
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=[]]]
java.lang.ArrayStoreException
at java.lang.System.arraycopy(Native Method)

at java.util.ArrayList.toArray(Unknown Source)
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 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:

<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 is
puzzeling as here is the output from my own local runs:

<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
