Actually to debug web app remotely you have to add the following command lien options to tomcat: -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n or run it using command line: catalina jpda start

Take a look here for details. Then you should connect to debug port using Eclipse (Run/Debug Configurations/Remote Java Application). But you are using GWT, so the better way to debug it is to refer to the GWT manual. GWT has a beautiful set of debugging tools.

To debug through eclipse you must have run tomcat in debug mode. So first of all set following params in catlina file in bin as

set JPDA_TRANSPORT=dt_socket set JPDA_ADDRESS=5050

Then run tomcat server by using one of the following command from respective directory

..\jakarta-tomcat-5.5.7\bin>catalina jpda run ...or... ..\jakarta-tomcat-5.5.7\bin>catalina jpda start

I am using "jakarta-tomcat-5.5.7".

Then go 2 eclipse and setup for debug mode

in left tab select remote java application then select your respective project and set your connection properties.

Now you can debug.
