Hi ant,
Thank you for the replies; I have made some small changes to have my service
exposed via binding.jms. I don't think this is the right way, but it works for
me atleast for the time being. What I have done is added another bundle which
will register an ActiveMQConnection factory object in the osgi service registry
and made changes in the JMSREsourceFactoryImpl in org.apache.t.s.b.jms.provider
bundle to access this same connection factory. This helped me to get my service
part working.
The following method is modified in the JMSResourceFActoryImpl class...
protected void createConnection() throws NamingException, JMSException {
ConnectionFactory connectionFactory
=(ConnectionFactory)jndiLookUp(connectionFactoryName);
if (connectionFactory == null) {
// TODO: connection factory name may be a non-jndi name OSGi
complaint lookup.
BundleContext bundleContext =
FrameworkUtil.getBundle(this.getClass())
.getBundleContext();
ServiceReference sr =
bundleContext.getServiceReference(ConnectionFactory.class.getName());
if(sr != null) {
connectionFactory =
(ConnectionFactory)bundleContext.getService(sr);
}
else{
throw new JMSBindingException("connection factory not found: "
+ connectionFactoryName);
}
}
connection = connectionFactory.createConnection();
}
Also I have implemented the lookupPhysical(String jndiName) method in the same
JMSResourceFactoryImpl using the same ConnectionFactory object registered in
the service registry of the OSGi runtime.
On starting the service bundle I get the console output as
----------------Console O/P---------------------------
Nov 26, 2009 10:22:42 AM
org.apache.tuscany.sca.binding.jms.host.DefaultJMSServiceListener

INFO: Add endpoint - (@19275957)Endpoint: URI =

------------------------------------------------------------------
Currently I am looking at how to make a client use this service. The client
reference running in another osgi runtime is not able to use this exposed
service. I get error here as referenced service not found.
My client composite is somewhat like as shown below.
<component name="HelloWorldClientComponent">
<tuscany:implementation.osgi bundleSymbolicName="HelloWorldClient"
bundleVersion="1.0.0" />
<service name="HelloWorldClientProcessor">
<binding.ws/>
</service>
<reference name="serviceA">
<binding.jms
initialContextFactory="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
jndiURL="tcp://localhost:61616">
<destination jndiName="DestQueueA"/>
<response>
<destination jndiName="RespQueueA"/>
</response>
</binding.jms>
</reference>
</component>
If I start my client I get the following error...

Would you able to comment on what is creating the problem? Thank you and
appreciate very much your comments and support.

Hi Roshan, sorry I've been snowed under and not had much of a chance
to look at this yet so dont have much to add here. I'll try to look at
it more shortly and maybe try to get one of the other Tuscany OSGi
experts to have a look too as its more of an OSGi runtime thing than a
JMS binding issue.
