Doubt in Action Form

Hi Raaja,

Thanks for your reply.

I have written the code for checking from database. In this code if the email id already exists in the database, it is not storing once again but the error message is not displayed and also i have tried by using logic tag. Both the scenarios are not working.How to solve the problem.

Jsp code
