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?
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 :-(
