Retrieve ObjectName of webapp without id

[chicklin]

Hi,
I'm trying to write a very simple web page to monitor the status of some other services and web apps. I have no problem retrieving an ObjectName of the services using "domain.com:service=ServiceName", etc., but it appears that the only way to retrieve a reference to the web app is by knowing the id, i.e. "jboss.web.deployment:war=file.war,id=4328178775". The problem is that this id changes depending on where I'm deployed. Is there a way to retrieve this without the id, or is there a way to look up the id programatically? I've tried "jboss.web.deployment:war=file.war,id=*" and "jboss.web.deployment:war=file.war,*", neither work.

Sorry if this is an easy one, I'm a little new to JMX. Thanks in advance!

The "jboss.web.deployment:war=file.war,*" should work. Are you using the MBeanServerConnection.queryNames() method? That should return a Set of ObjectName objects that match the query.

This is what I'm using to query my services (e.g. an SMTP service):

ObjectName smtpService = new ObjectName("domain.com:service=SmtpService");
 setSmtpStatus((String)server.getAttribute(smtpService, "StateString"));

Like I said, you need to use the queryNames method to get all mbean names what match a wild card. For example:

ObjectName on = new ObjectName("jboss.web.deployment:war=file.war,*");
Set mv = server.queryNames(on, null);

Each entry in mv is an ObjectName of a matching mbean. In this case, there should be at most one name in the set.

That did the trick. Thanks!
