WebLogic 10.3 JMX

April 9th, 2009 by Jan Kronquist — Java

Jan Kronquist

I have been using Oracle WebLogic 10.3 for a while in my current assignment. I wanted to publish my own custom MBeans and be able to see and edit properties and invoke methods on them. However, the built-in management console does not support custom MBeans (without adding custom configuration). I ended up using JManage which is an open source management console implemented as a web application.

The problem was that JManage 2.0-RC1 does not support WebLogic 10.3 and their last release was made two years ago. However, since they support version 9 I figured it might be possible to upgrade the jar files to make it work with 10.3. This is how you do it:

In the folder $JMANAGE_HOME/modules/weblogic9 remove wljmxclient.jar and add wlfullclient.jar and com.bea.core.descriptor.wl_1.1.0.0.jar instead. Here are the instructions how to create the wlfullclient.jar. The other jar is included in $BEA_HOME/modules.

I have also tried jconsole, the built-in WLDF console extension and wlnav but all of them had problems:

  • To make jconsole work remotely you must change how the WebLogic server is started. As I really want to use the standard installation package this won't work
  • The WLDF console does not allow method invocations and I can only get it to show the built-in MBeans
  • wlnav is built on wlst and seemed very powerful, but was quite ugly and I couldn't find my custom MBeans

    • Although JManage is good enough for my current purposes I am interested in other alternatives for remote JMX management of WebLogic!

    Hi Jan, nice topic, and nice tip for jManage, I had implemented it.
    Thank you.

    Did you try JRockit Mission Control as JMX Console ? (only if you run weblo using jrockit). Maybe it is a goog way to manage MBeans.

    Moreover, I’m investigating BEA MBeans in order to know wich counter are interesting to monitor Health/Load and throughput of my Application. Could you advice me wich MBeans seems interesting ?

    I didn’t try JRockit Mission Control, thanks for the tip. But this probably also has the same problem as JConsole, ie I need to change how WebLogic Server is started to be able to connect using a standard Java 5 connector.

    I also really wanted to have a webpage which our testers could use without having any extra applications installed. I also needed to access JMX during development and the recommendation is to use Sun JVM during development.

    You can also use JManage to connect to WL 9.x and 10.3 if you use the WL 9 weblogic.jar. The URL did change for 10.3 to

    service:jmx:t3://localhost:7001/jndi/weblogic.management.mbeanservers.runtime

    excellent documentation on the configuration and troubleshooting the configuration of JManage for weblogic 10.3 server.

    Dear Jan,

    I changed the jManage tool as per your recommendations, but I could not access the Mbeans as I use https protocol to access console.
    This is how I did to access

    service:jmx:t3s://localhost:7001/jndi/weblogic.management.mbeanservers.runtime

    #Bansidhar: I haven’t tried that, let me know if you figure it out.

    Dear Jan,

    I uploaded webserviceclient+ssl.jar to JManage as it involves ssl connectivity to weblogic, but I see below error in the logs. Could you please advise how to fix this?

    Thanks,
    Bansidhar

    Did you connect to a managed WL server or the admin server (so you could see all MBeans)? Also what url format did you use (a sample would be great)?

    Hello,

    Can you please help me in resolving this

    We have a weblogic server and from my local system jconsole i am trying to connect to that server using JMX using below mentioned URL

    service:jmx:rmi:///jndi/iiop://b0d0fr22.ch.zurich.com:14124/weblogic.management.mbeanservers.runtime

    but while conencting its displaying belwo mentioned exception
