The taglib directive below imports the JSTL library. If you uncomment it, 
you must also add the JSTL library to the project. The Add Library... action 
on Libraries node in Projects view can be used to add the JSTL 1.1 library.

thats the jsp page which is connected to the datbase
and a html page in which user inputs username , password security question all that
but i am receiving errors can u help
it compiles but gives me a lang.java null pointer exception i have seached about this exception and tried to rectify but was unsuccessful

That exception occurs when you try to call a method on an object variable that is null. Look at the error message and it will tell you which call caused the error. Then you must figure out why that variable is null at the point you are trying to use it.

What i dont understand is that your mixing Java code and JSP code, wouldnt it be neater if you just had html / jsp code in the jsp itself and then have a seperate JAVA class for the other code?
