Can't debug servlet Eclipse + Glassfish

The server is in debugging mode. I've set 10 breakpoints and the browser just skips them all. Why? This happens with JSPs also in that proje开发者_StackOverflow中文版ct. Why?

Have you checked that the Debbuger is indeed connected with Glassfish? Also please note that it is not possible for the debugger to stop at breakpoints which have been set inside jsp. AFAIK, debugger works only pure java code

So you are connecting to external server with "debug remote java application".

What is your server's debug port? Port 8000 is default setting in eclipse debug configuration for remote java appilcation. You should change that value to one that GlassFish server is configured for debugging.

Also, take a look at How do I debug GlassFish 3 using Eclipse Helios?
