session in jsp getting null value on getAttribute

I have the addedit.jsp page

where I am inserting myinput in a textarea

your input
    <input id="thistextfield" type="text"  name="ruleField" size="20" >
    <input type = "submit" name = "submit" value = "submit">

<a href="SaveName.jsp">to savename</a>

my session gets stored in this page

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page import="java.lang.String" %>

<%
    String ruleField = request.getParameter( "ruleField" );
    session.setAttribute( "theName", ruleField );


%>
<html>
<head>
    <title></title>
</head>
<body>
<a href="test2.jsp">Continue</a>
</body>
</html>

Here is my text2 page. where I am supposed to get back the session

Hello,<textarea > <%= session.getAttribute("theName")%>  </textarea>

but the problem is that I get a null value in my textarea. And I am using IntelliJIdea 12 and the getParameter and getAttribute show up in red as cannot resolve method.

You have missed out the HTML form tags in addedit.jsp. Therefore when you click on the link 'to savename' you are not sending the form data 'ruleField' as a parameter in the request, you are not sending any data, that is why it is null.

Make the following changes to the addedit.jsp:

<form method="GET" action="SaveName.jsp">
    <input id="thistextfield" type="text"  name="ruleField" size="20" >
    <input type = "submit" name = "submit" value = "submit">
</form>

and remove the following HTML (this is superfluous): 

<a href="SaveName.jsp">to savename</a>

I had thought that you might want to use a link to submit the form rather than a button. Here is alternative code that uses the link to submit the form.

<form method="GET" action="SaveName.jsp" id="form1">
    <input id="thistextfield" type="text"  name="ruleField" size="20" >
</form>

<div onclick="document.getElementById('form1').submit()">to savename</div>
