On JBossProfiler.war there is a WebInterface that will automate the navigation on JVMTIInterface. Go to http://localhost:8080/jboss-profiler Look at the third option on the Menu. That will intercept class references in a Tomcat/JBoss instance. You will need JVMTIInterface (the MBean) deployed as well. You can redeploy your application couple times, forcing classes being loaded twice, and look for duplications. You can play with Clean Session and get duplications again every time you execute a redeployment. The application will "download" a matrix from C++layer into Java Layer. If you redeploy the matrix will be out dated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967506#...
