This is a lightweight JMX console implemented as a Groovlet (Servlet in Groovy)

Add Groovlets support to you web.xml like this:

    <servlet>
        <servlet-name>Groovy</servlet-name>
        <servlet-class>groovy.servlet.GroovyServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Groovy</servlet-name>
        <url-pattern>*.groovy</url-pattern>
    </servlet-mapping>

Then place the jmx.groovy, *.js and *.css files in your war, then access 
http://localhost:8080/war_name/jmx.groovy
