Re: Please help me figure out this....
Yes, you should not use
return (name=="abc" passwd=="123 ");
but
return (name.equals("abc") passwd.equals("123"));
This will probably fix your problem.

Subject: Please help me figure out this
I have login.html calling a servlet (loginHander) which handles
authorization. If user is validated, the servlet will redirect the user to
Welcome.jsp
My problem is I could not pass the value of user and password from
login.html to loginHandler. I set the boolean method loggedIn so that when
user name is
abc and password is 123 the user should log in. However, this somehow can
not be accomplished. Even I entered abc as name and 123 as password, I was
bounced back to login.html page.
I am using Orion 1.47.
Please help!

RE: Please help me figure out this....
You should use name.equals("123") instead of use name=="abc"
Please make sure that you understand the difference beetween
name.equals("123") and name=="abc"
