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
