how to debug the servlet

[tommy]

I use the "system.out.println" even if it is very silly way

Is there any good way to debug it?
I mean I want to see the message that I use the "system.out.println"

thanks

What application server / web container do you use to run your servlet?

What IDE / editor do you use?

You need to figure out how to enable debugging support on your app server.

Then, if you don't have one already, find an IDE that has a debugger. Eclipse is a free IDE that fits the bill. I don't use it myself, unfortunately, so I can't tell you how to use its debugger.

Also, you need to make sure that you compile your servlet with debugging info: the -g option.
