Error messages and stack traces would help.

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.

thank u problem solved

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