You could use a logging framework other than log4j, or you could run the application in a debugger.

Using an actual debugger is my choice. I use myEclipse workbech with Eclipse. It allows you to set breakpoints and step through. At the same time you can view all values, step into, step over, step to return...

Debuggers are very useful and I always use one for development. However released code tends to run in environments where you can't use a debugger, so it is no substitute for proper logging.

so majority of the people suggest me to go for inbuilt debugger which is present in eclipse ?
am i right?
but i havn't know how to debug my webapplication in netbeans IDE

and thanks

If you really want to use netbeans, try this link:
