How to look up a JMS Topic via the Kernel?
Hi,
I have a GBean from which I need to grab a reference to a JMS
TopicConnectionFactory and a JMS Topic. Currently, I am attempting to use
the GBean Kernel API to grab these references. I have succesfully
retrieved the TopicConnectionFactory using the following method:
----
public TopicConnectionFactory getTopicConnectionFactory( String
aTopicConnFactoryJndi )
{
TopicConnectionFactory lTopicConnFactory = null;
Kernel lKernel = KernelRegistry.getSingleKernel();
Iterator lConnectorIt =
lKernel.listGBeans(
new AbstractNameQuery(
"org.apache.geronimo.management.geronimo.JCAManagedConnectionFactory"
)
)
.iterator();
try {
while ( lConnectorIt.hasNext() ) {
AbstractName lName = ( AbstractName ) lConnectorIt.next();
String lConInterface =
( String ) lKernel.getAttribute( lName,
"connectionFactoryInterface" );
if ( lConInterface.equals( "javax.jms.TopicConnectionFactory" )
) {
String lPoolName = lName.getNameProperty( "name" );
if ( lPoolName.equals( aTopicConnFactoryJndi ) ) {
lTopicConnFactory =
( TopicConnectionFactory ) lKernel.invoke( lName,
"$getResource" );
break;
}
}
}
} catch ( Exception e ) {
throw new RuntimeException( "Could not retrieve topic connection
factory", e );
}
return lTopicConnFactory;
}
----
However, I do not know how to retrieve a JMS Topic using the same technique
as I don't know what my AbstractNameQuery should be, nor what attributes of
the GBean I should be searching for. Does anybody know how to do this?
Thanks,
Aman

Thanks! I tried that and it worked...I don't think I would have been able
to figure that out.

For the ANQ try something like
#org.apache.geronimo.connector.AdminObjectSource
or
#org.apache.geronimo.connector.AdminObjectWrapper
and try the adminObjectInterface or adminObjectClass attributes.
You call $getResource on these as well to get the actual admin object.
Hope this helps.
we need to get an easy way for these to get into global jndi, this is
ridiculously complicated :-(
