[xmlblaster-devel] Working with MBeanServer in xmlBlaster

["Arghad Arnaout" <arghad at gmail.com>]

Hallo .. 

I was playing arround to check how I can build a monitoring tool based on the MBeanServer in xmlBlaster, and I found my self stuck in non well documented api org.xmlBlaster.client.jmx, so here what I have tried to do and I hope someone helps me in this issue....

 

1- I have tried to run the example in org.xmlBlaster.jmxgui.Main, but it stucks and does not execute.

2- I tried to figure out what is the problem and I found the following:

When the method getMBeanInfo executes in the class ConnectorClient it hangs  in the following lines (107,108):

      RequestBroker = new ObjectName(name);
      mbInfo = (MBeanInfo) aServer.getMBeanInfo(RequestBroker).get(); 

Here the method getMBeanInfo() returns a callback-object: org.xmlBlaster.client.jmx.XmlBlasterCallback and the client application will be stop here and not continue to the next statement.

 

Frankly I did the same thing in a stand-alone java application but I could not move faster than this, here is the code:

 

1: I_XmlBlasterAccess con = utilGlob.getXmlBlasterAccess();

2: ConnectorFactory factory = ConnectorFactory.getInstance(utilGlob);

3: AsyncMBeanServer server = factory.getMBeanServer("127.0.0.1");

4: ObjectName requestBroker_name = new ObjectName("xmlBlaster:name=xmlBlaster");

5: org.xmlBlaster.client.jmx.Callback callBackObj = (RequestBroker) server.getObjectInstance(requestBroker_name);

6: this.requestBroker = callBackObj.get();

 

so the program will hang at line 5.

 

I tried the tool jconsole and it worked fine.

So the big question is why the factory org.xmlBlaster.client.jmx.ConnectorFactory returns AsyncMBeanServer instead of MBeanServer, I think if somebody aswers me to this question, so we can pass over this problem, and if we should use AsyncMBeanServer so how we can get the RequestBroker instance from it ???

 

Sorry for this long msg

Thank you very much.
