plz help as urgent as possible

Edited 3 Years Ago by happygeek: fixed formatting

there is no error messages and i dont know how to code trace plz help me i need it urgently

I'm sorry, but that says it all.

The application server you are using to server these pages has a log. The errors should be found there. And I said nothing about a "code trace". I said a "stack trace", these should also be in the log file, probably directly after the error message, as long as the application server is not configure to prevent them.

what includes J2EE means whats the specification for j@EE does it include EJB and STRUTS
