I've deployed some Managed Beans on WebSphere 6.1 and I've managed to invoke them through a standalone client, but when I try to use the application "jconsole" distributed with the standard JDK can can't make it works.
Has anyone achieved to connect the jconsole with WAS 6.1?
IBM WebSphere 6.1 it's supossed to support JSR 160 JavaTM Management Extensions (JMX) Remote API. Furthermore, it uses the MX4J implementation (http://mx4j.sourceforge.net). But I can't make it works with neither "jconsole" nor "MC4J".
I have the Classpath and the JAVA_HOME correctly setted, so the issue it's not there.
WebSphere's support for JMX is crap. Particularly, if you need to connect to any secured JMX beans. Here's an interesting tidbit, their own implementation of jConsole will not connect to their own JVM. I have had a PMR open with IBM for over a year to fix this issue, and have gotten nothing but the runaround. They clearly don't want to fix this issue.
The only way I have been able to invoke remote secured JMX beans hosted on WebSphere has been to implement a client using the "WebSphere application client". This is basically a stripped down app server used for stuff like this.
Open a PMR with IBM. Perhaps if more people report this issue, they will actually fix it.
Update: You can run your application as a WebSphere Application Client in RAD. Open the run menu, then choose "Run...". In the dialog that opens, towards the bottom on the left hand side, you will see "WebSphere v6.1 Application Client". I'm not sure how to start and Application Client outside of RAD.
