I'm running windows2000 and JRun 3.0
My servlet:
1) Creates & populates an instance of my class called JournalEntry.
2) puts it into the session,
3) passes control to a JSP page for rendering
Everything works fine, the class is passed to the JSP, and is displayed
properly.
However, when I recompile the servlet, with the JRun server still running,
all subsequent requests throw an exception.
This applies to both existing and new sessions. I must restart the jrun
server for it to work again.
Thanks for any expert assistance!
Supporting info is below...

Relevant code snippets below:
============================
Servlet:
JournalEntry je = getJournalEntry(requestedId);
HttpSession session = req.getSession();
session.setAttribute("journalentry", je);
ServletContext sc = this.getServletContext();
RequestDispatcher rd = sc.getRequestDispatcher("/journalentry.jsp");
if (rd != null) {
try {
rd.forward(req,res);
} catch (Exception e) {
sc.log("Couldnt pass to journalentry.jsp", e);
}
}
JSP:
<%
journal.JournalEntry je =
(journal.JournalEntry)session.getAttribute("journalentry");
URL url = je.getUrl();
%>
