JavaMelody mapping URL

Question

I'm trying to install Javamelody in my Spring application. I configured on localhost and can access Javamelody with URL:

http://localhost:9080/myapp/stats

Server: webSphere 7.0 and my web.xml config is:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

However, this config in production environment is not working. If I go to

http://app.gtrwe.dev.corp/myapp/stats

I get 404 error. Also I have servlets in my web.xml

I am looking for help on how to set this up.

Answer 1

It seems that IBM WebSphere may encounter the ERROR 404 if no servlet is mapped to either /* or /monitoring, as mentioned here
