I have created a JSP page(index.jsp),success page(success.html),error page(error.html) and a servlet page(Login.java).

Now i want that whatever information the user enters in the login for(that is index.jsp)..that information should be stored in the SQL.

I have tried the following code:-

index.jsp:-

You're in hell :), I don't really read all this code but:
why you use this?

<form action="success.html" method="get" />

maybe should be:

<form action="/Login" method="get">
... your inputs here
</from>
</form>

also isn't a parameter name this is *label*

String fn =request.getParameter("First Name");

see in your html

------------------------------------[HERE]
<td><center><font color="black"><b>First Name </b></font></center></td>
<td><center><input type="text" name="name"></center>

</input>

than try to run your page and see errors, maybe without errors no one can give you any solution.
