debugging in NWDS

Hi,

I am trying to debug an application.

I have built the project and exported into a war file.

Later I uploaded it to Webconsole and deployed to the MI client.

I try to debug the application,the mi client is launched.

I login and try to access the application. As soon the break point that I have inserted becomes active

the application hangs. I am not able to use the functions Step into,Step over etc. Is there any problem in the way that I have built or is there something called building in debug mode.

Regards
