JEE Webapp Troubleshooting Tool

To help troubleshoot a web application, it is useful to print out information about the JEE server and the HTTP request.

I created a JSP page called serverinfo.jsp to display information about the server, Java memory, classpath, HTTP Session, and cookie.

I have used this tool numerous times in production to troubleshoot issues with load balancing, dropped sessions, bad cookies, and OutOfMemoryExceptions.

The source code is on GitHub .
