Hi Dilip

could you please tell me how to start debugger in Ax3.0 enterprise portal?

Please try this:

If i recollect correctly, there's a class called WebSession in 3.0 which has an init method which is the entry point. Please try it and let me know.

Hi Dilip

Thanks for the information.
Is there any possibilities that we can debug in client machine? by using console session, we will have limit access to the server for debugging.
