JSP/form/servlet - session persistence ?

[Louis Cypher]

Hello,

a JSP page contains a from that, when submitted calls a servlet (specified in the action attribute) that sets an attribute in the session scope and gets back to the jsp page ( it besides the form contains a few jstl tags that display the data entered in the form.)

Now, when cookies are enabled, everything works fine, but when they are not, I can't figure out how to maintain a single session across jsp -> servlet -> back to jsp

What is the best practice approach in my case ?

Regards!

URL rewriting.

URL rewriting is what I'm trying to introduce but how do I send a sessionid back to jsp ?

Something like :

String url = response.encodeURL("page.jsp");
RequestDispatcher rd = getServletContext().getRequestDispatcher(url);
rd.forward(request,response);

?

I think I got it :

<c:url var="url" value="servletURL" />
<form action="${url}" method= ......

in the jsp will do the job.

Please correct me if I'm wrong or suggest a more convenient way ( if any) to achieve the same ...

Nope, that's about it. You could use the url tag inside the form tag "action" attribute, but that can look a little messy-matter of preference.
