I have simple servlet that passes parameter to jsp file. Here is the code:
String userName = request.getParameter("userName");
HttpSession session = request.getSession();
session.setAttribute("userName", userName);
request.getRequestDispatcher("welcome.jsp").forward(request, response);
The page welcome.jsp contains:
<body>
<h3 align="center">Welcome ${userName}!!!</h3>
<a href="index.jsp">go back</a>
</body>
The index.jsp:
<form method="post" action="check">
Name <input type="text" name="userName" >
<input type="submit" value="submit">
</form>
Finally web.xml:
<servlet>
<servlet-name>check</servlet-name>
<display-name>check</display-name>
<description></description>
<servlet-class>MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>check</servlet-name>
<url-pattern>/check</url-pattern>
</servlet-mapping>
Problem is that parameter is not passed to welcome.jsp. I still see
$userName
What is the problem? Please help me.
