And you've verified that link.toString() actually is a a valid URL? What
happens when you put that in the browser? You get the null pointer
exception?
You not using cookies for session then right?
ie. you don't want to pass that stuff in as a cookie?

> If anyone has better code to read in JSP for its dynamic output, I am all

> <%
> Object o = null;
> System.out.println(o.toString());
> %>
>
> <my-tag>
> </my-tag>

> The JSP page will "break" at run-time, throwing a Null Pointer Exception.

> "open" the
