Inspecting a bean in my JBOSS JMX Agent View fails with an error

Question

I cannot inspect any of my beans in the JMX Agent View as clicking on any bean results in the error pasted below. Every thing else seems to be working fine within JBOSS as it is properly serving my application.

Environment variables as follows...

PATH = C:\Program Files\Java\jre8\bin;C:\Users\XXX\AppData\Roaming\npm;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files\Java\jre7\bin;

JAVA_HOME = C:\Program Files (x86)\Java\jdk1.8.0_05

Answer 1

This worked in jboss-4.2.3.GA: In file

/server/{xxx}/deploy/jmx-console.war/inspectMBean.jsp

replace the affected

replace("\"",""")

with

replaceAll("\"",""")

Answer 2

Had the same thing happening.

Turns out I was missing inspectMbean_jsp.class in the dcm4chee-2.17.2-psql\server\default\work\jboss.web\localhost\jmx-console\org\apache\jsp folder.

Not sure why it isn't there
