did you try this:
<% String id = request.getParameter("cid") ;
if(request.getParameter("cid") != null)
{
out.println("Hello ") ;
out.println(id) ;
}
else
{
response.sendRedirect("D:\\jswdk\\jswdk-1.0.1\\examples\\WEB-INF\\servlets\\
login.html") ;
} %>
like I posted before?

Subject: If condition in jsp
Hi ,
I am new to jsp and want to design a form. The form has 2 fields id and
password. I want to check in jsp whether if the field is null then re-direct
him to login.html again. Below is my code, if i am sending blank id field
still i am getting hello printed on the browser but i want it to redirect to
login page.
login.jsp
<html>
<head>
<title> Login Successfull </title>
</head>
<body>
<%@ page language="java" %>
<% String id = request.getParameter("cid") ;
if(id =="" || id == " " || id == " ")
{
response.sendRedirect("D:\\jswdk\\jswdk-1.0.1\\examples\\WEB-INF\\servlets\\
login.html") ;
}
else
{ %>
Hello <%=request.getParameter("cid") %>
<% } %>
</body>
</html>
Thanks in advance.
Mahesh.
