So I go the bin folder of jboss instalation directory and I execute run.bat and everything is ok but when I open JConsole and I try to connect to jboss process in local processes section I get the next exception: '' 21:10:02,437 INFO [STDOUT] javax.management.JMRuntimeException: Failed to load MBeanServerBuilder class org.jboss.mx.server.MBeanServerBuilderImpl: java.lang.C lassNotFoundException: org.jboss.mx.server.MBeanServerBuilderImpl 21:10:02,437 INFO [STDOUT] ..... Agent failed to start! I have tried many configurations in the run.bat and in the run.conf files of jboss but I get the same exception. I have checked the in the lib folder of jboss that the library jboss.jmx_jar has the class "org.jboss.mx.server.MBeanServerBuilderImpl". Any ideas, please?
