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

This worked in jboss-4.2.3.GA: In file

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

replace the affected

replace("\"","&quot;")

with

replaceAll("\"","&quot;")

I can confirm that this solution works but I only tested it for jboss-4.2.3GA as well using JDK 1.8. Don't know whether it works for other versions of JBoss. It's important to mention here that all occurrences of the `replace` function need to be replaced by `replaceAll` (lines 21 and 22 in my version of the file). – pemistahl Feb 15 '16 at 13:10
Thanks. Best Solution especially when you are upgrading JDK. – Sujjad A Mar 30 '21 at 08:28

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

Will check this out in a few hours. Thank you for the response as this question had previously earned me a tumbleweed merit badge. – mccainz May 12 '14 at 19:07
what version of java are you using? I was using 1.8 and it wasn't working but 1.7 works fine – AThom May 12 '14 at 20:06
I think I may be using 1.8 but I need to confirm as I have multiple versions loaded. – mccainz May 12 '14 at 20:10
Same issue using Java 1.8.0_05 – Cedric Simon Nov 09 '14 at 14:43

I think more graceful solution would be to ensure that both compilerSourceVM and compilerTargetVM are set to 1.5 or above in jboss/server/default/deploy/jboss-web.deployer/conf/web.xml as in How to change tomcat compiler.

Also JDK 1.5 or above should be present and visible instead of default JDK 1.4 which doesn't understand String.replace method with string params.
