<% %> and <%= %> are different things.

<h4>Welcome <%request.getParameter("loginname");%></h4>

The above line should be, <%= session.getAttribute("loginname") %>, i guess...

Also, I can't understand why you are checking the username and password null condition in an JSP, you could just check it in an servlet and then forward to welcome.jsp, if the condition is met, which would make the code and logic more clear...

Can you try doing this:
In VALIDATION.JSP replace 18th line
<jsp:param name="loginname" value="${param.loginname}"></jsp:param>

with <jsp:param name="loginname" value="${sessionScope.loginname}"></jsp:param>

because "
"param" will act as request.getParameter(String XXXX);
"sessionScope" as session.getAttribute(String XXXX);

The above should solve the problm
