With the current cvs-build as well as 1.2beta5 I get I NullPointerException everytime I do a right-click on a MBean in the "Managed Object Explorer". I'm using: - current non-developer cvs build - Java 1.4.2 - JSR160 connection to MX4J-2.0.1 On prior versions I got a context-menu in which I could select the available dashboards, invoke operations or open the properties. Steps to reproduce: - given the above configuration: connect to server - select a MBean - right-click on the MBean Here is the stacktrace: --snip java.lang.ExceptionInInitializerError at

Date: 2004-04-21 08:51 Message: Logged In: YES user_id=773314 Error handling added... but I recommend using the DTD to ensure dashboard compliance. ---------------------------------------------------------------------- Comment By: Greg Hinkle (ghinkl) Date: 2004-04-21 07:40 Message: Logged In: YES user_id=773314 Ah error handling... The problem here is that you have old dashboard files that have the old syntax. A new required element in the XML was added in b5 "DashboardMatch". Please make sure you are only using the latest dashboard files. I'll see if I can make the error handling a little more helpful. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=493495&aid=938730&group_id=60228 |
