Another question for you

DonalN

Can't see what's wrong with this

It's part of a simple login code in a JAva servlet

- Database has table with Username and Password fields

- The servlet takes the users input from a HTML form and check it against the database
- The string from the HTML form is called 'Username' and the string retrieved from the database is called 'usercheck'
- Same with the password; 'password' & 'passcheck'

I'm using this code to check validity

if((Usercheck == userName) && (Passcheck == password))
{
out.println("successfull");
}

but it's just returning a blank page..

I know this is simple stuff for most of you, but I'd appreciate some help...it's wreacking me head!

Thanks,

D.

1:
user enters username and password in html from and hits submit

2:
servlet gets username and password
You should do a check to see if username and password are

if(UserCheck == null)
   out.println("enter username");
if(PassCheck == null)
   out.println("enter password");

3:
get data from DB,
you only get the password not the username

"select password from table where username = ?;"
if(result.next()){
   if(passCheck.equals(result.getString("password")))
	out.println("successful");
   else
        out.println("password incorrect");
}
else
   out.println("username not in database");

4:
but it's just returning a blank page.
you should paste the whole servlet to see if you
have other problems.
