Hi Folks. I have searched the archives for information on how to register Logback to the JMX server in WebSphere and did not find any information. I did some research and found that IBM has two MBean servers. I posted information to the users mailing list on how to get WebSphere to use the platform server. I have also done some research and development on how to get Logback to register to the JSR160RMI connector. I modified the JMXConfiguratorAction class to look for a system property called ch.qos.logback.WebSphere to be set to true. If the property is set to true, it will register the MBean to the MBean server at the JSR160RMI connector instead of the platform MBean server. I have tested this at the level of a proof of concept. I would really like to see this feature be added to the code for Logback. I have included the source code as part of this post. Please feel free to contact me at dale.chapman@medavie.bluecross.ca if you have any questions or comments about this.
