2. Re: Retrieve listing of connection pools
dimitris Nov 4, 2004 12:42 PM (in response to bbalmer)If your MBean naming is consistent, you don't need to include a QueryExp in the call to QueryNames (just pass null as a second argument). QueryExp really refers to the actual attribute values of MBeans
Then use a appropriate ObjectName pattern, eg:
"jboss.jca:service=ManagedConnectionPool,*"
will get you all ManagedConnectionPools, under domain jboss.jca
Alter your connection MBean names if necessary -
3. Re: Retrieve listing of connection pools
bbalmer Nov 4, 2004 12:54 PM (in response to bbalmer)Thanks for your quick reply. I changed my code to:
ObjectName scope = new ObjectName("jboss.jca:service=ManagedConnectionPool,*");
QueryExp exp = Query.initialSubString(Query.attr("Name"), null);
Set set = server.queryNames(scope, exp);
log.info("Found " + set.size() + " pools");
Iterator it = set.iterator();
while(it.hasNext())
log.info(it.next());
And it still found 0 results. Am I still doing something wrong? Should I not be using Query.initialSubString? -

dimitris Nov 4, 2004 1:06 PM (in response to bbalmer)You do NOT need the QueryExp:
ObjectName scope = new ObjectName("jboss.jca:service=ManagedConnectionPool,*"); Set set = server.queryNames(scope, null); log.info("Found " + set.size() + " pools"); Iterator it = set.iterator(); while(it.hasNext()) log.info(it.next());

What is the difference between the follwing MBeans ? Does "JmsXA" is
the connectionpool name?
"jboss.jca:name=JmsXA,service=ManagedConnectionPool "
"jboss.management.local:J2EEServer=Local,ResourceAdapter=JMS Adapter,j2eeType=JCAResource,name=JmsXA" -
7. Re: Retrieve listing of connection pools
dimitris Nov 12, 2004 2:05 AM (in response to bbalmer)MBeans in the "jboss.management.local" domain are JSR77 compliant "proxy" objects, modelling in a standard way some management aspect of the server. So, for example, if you deploy an .ear or a .rar you'll see a number of them being created.

9. Re: Retrieve listing of connection pools
dimitris Nov 16, 2004 5:57 AM (in response to bbalmer)If you look into the code (org.jboss.management.j2ee.JCAResource) you'll see there is no chance to get anything else than a single array entry:
ObjectName jsr77CFName = getConnectionFactory(0); Object[] params = {poolServiceName}; String[] sig = {ObjectName.class.getName()}; JCAConnectionPoolStatsImpl cfStats = (JCAConnectionPoolStatsImpl) server.invoke(jsr77CFName, "getPoolStats", params, sig); JCAConnectionPoolStatsImpl[] poolStats = {cfStats}; stats = new JCAStatsImpl(null, poolStats);
I'm not an jsr77 expert, so I suggest you read the spec to be certain what is the expected behaviour. If you spot a mistake in the implementation, post a bug to sourceforge. If something is missing post a feature request, (or better, contribute it yourself :)
