Hi folks
I am doing a project for which i need to display the error message to the same login.jsp page using servlet.Error messages should be of there types:
For invalid username:invalid user name
For invalid password:Invalid password
For Invalid username or password:user details are not found in database
I am doing these validation against MS-Access Database.
I have written a code which is giving only one type of error:
Thats :For Invalid username or password:user details are not found in database.
Please help me out.Thanks in Advance


This code is working fine for the third type of Error.
I have also written a code to display all the three errors.But it is not working

Welcome to Javaranch

your logic[the way of querying the DB] is false. check the DB for username,if it is not in DB,then show first error message else go for password checking..and etc... go ahead.

but really what is the use of displaying these many errors ?
 
I agree. Here's the link: http://aspose.com/file-tools
