Answer 1

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.

Answer 2

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.
