porting mx4j from java 1.4 to java 1.5
[294 byte] By [DiegoCarzanigaa] at [2007-11-26 23:45:02] 
Hi everyone,I implemented an application using JMX support offered by mx4j. Now I have to switch from java 1.4 to java 1.5... my code must be compatible with the two JVM.Does anyone know how to obtain this result?Thank you very much all in advanceDiego

Hi Diego,
Are you using any MX4J implementation specific API?
Java SE 5.0 has its own implementation of JMX, so if you're only using public
JMX APIs defined in javax.management and subpackages, your code should
compile and run right away on Java SE 5.0. You won't even need the
MX4J packages in your classpath.
Give it a try.
If you're using MX4J implementation specific APIs (or MX4J specific protocols)
not covered by the JMX standard then you'll have to do a deeper analysis.
Best regards,

Thank you very much Daniel!
My problem was that some mx4j class was implemented also by JAVA 1.5 core API (rt.jar). So at loading time JVM loaded rt.jar classes... not mx4j.jar classes. I solved the problem putting mx4j.jar in endorsed directory... in this way classes are searched in mx4j.jar first than in rt.jar.
Best regards

Hi,Have you tried *without* any mx4j jars?Putting mx4j jars in the endorsed directory is not something I would recommend.Best regards,-- daniel http://blogs.sun.com/jmxetcdfuchsa at 2007-7-11 15:17:02 >

Yes I tried but the application, once started, was blocked on a infinite loop in the method scanTag... which performs parsification of mbeans.mlet file. Probably there are differences between mx4j implementation an rt.jar implementation regarding to this parsification function.
I'll investigate better.
Thank you very much again.
