How to get RequestDispatcher parameter in forward target html

StackOverflow https://stackoverflow.com/questions/19993085

Question

guys, I want to pass values from one html page to another. In test1.html, submit the value to Serlvet. In servlet got the value, and dispatcher request to test2.html. like this:

request.setAttribute("url", url);
request.getRequestDispatcher("test2.html").forward(request,reponse);

So, how can i get the "url" value in test2.html?. need help, thx!

Was it helpful?

Solution 

request.setAttribute("url", url);
request.getRequestDispatcher("test2.jsp").forward(request,reponse);

then test2.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
${url}
</body>
</html>

OTHER TIPS

As the forward is entirely server-side, the attribute should still be present in the request. So from test2.html (actually you should make this a JSP page, test2.jsp), you can do the following:

<%
String url = (String)request.getAttribute("url");
%>

And if you wish to display it:

<html> ...
    The URL is: <%=url%>
</html>
