what to do when a session expires?
Hi- I'm in the Servlet->Bean->JSP model, and I have a login page that calls a login servlet, which in turn instantiates a session-bean used by the output page. The user then continues to navigate a series of JSP pages, all of which use this same session-bean. My question is, what is the proper way to handle the session expiring if the user lets it sit for awhile? The currently displayed JSP page will post data back to a servlet which will reinstantiate the bean. It then needs to recognize that the user needs to log in again and return back the login page. But how do you sustain the post data, and how does the login JSP know which function the user was trying to do before the login page interrupted the flow of logic? I'm sure I could hack out a solution, but this must be a common problem so I'm assuming there is a proper method for doing it. Any help greatly appreciated! Thanks! -Richard

Beans do not expire, and they do not get invalidated. Those concepts apply
only to sessions. The only thing that the servlet engine will do to user
data objects associated with a session is to remove them from the session
when it is invalidated (either because it timed out, or because you called
invalidate() yourself).
However, your servlet or JSP code can remove a bean from a session any time
it wants to:
session.removeValue("TheKey");
Likewise, if you call something like
session.putValue("TheKey", aNewObject);
and there was a previous object bound to that key, the previous object is
removed.
If your bean itself wants to know when it is being added to, or removed from,
a session, have it implement the HttpSessionBindingListener interface. See
the servlet API specs (and API docs) for more information about this.

Bean Expiration
Is there any possibility for one Bean to expire before other Beans? It appears to me that it should not be possible, since it is the session that expires and not the Beans. I want to make sure that it is good enough for me to check for the existence of one Bean in order to insure that other ones exists (granted I have created them somewhere). Can anything happen in the JVM that would somehow invalidate a Bean and remove it from the session ? Please give me your thoughts!!

Which one is better ?
Hi all , I was earlier using applet/servlet combination for a Web based reporting system.applets formed the front end.servlets handled the database access part. What I am investigating now is whether I can improve the speed of the application by using the JSP/servlet combination or not. Do you guys have any opinions in this regard ?I would be pleased to hear from you all.

Dynamically generating JSP
Hi. I am toying with JSP here, and I came up with the following problem. Is it possible to get JSP pages from somewhere other than a file? I.e. can I, for example, store them in a database and retrieve on demand? Now the obvious solution, of chaining a servlet in front of the JSP page and using this servlet to retrieve the page, save it to disk, and then calling JSP wouldn't really work. For one thing, it would force a re-compilation of the JSP page on every hit. (Yes, I can get into the business of managing an on-disk cache from the database, yada-yada-yada...) But is there a way to re-define "code load" handler in JSP? I looked through GnuJSP implementation (the only one I have source for) and it does not appear so... Any thoughts? _/_/_/_/ _/_/ _/ _/ http://Orbit.Stanford.EDU/~alik _/_/ _/_/ _/ _/ _/_/_/_/ _/_/ _/_/ ftp://Orbit.Stanford.EDU/people/alik/ _/_/ _/_/ _/ _/ _/_/ _/_/_/_/ _/ _/ _/ mailto:[EMAIL PROTECTED] === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JSP-INTEREST".

32 Ko limitation in JRun ?
I don't know whether it is normal or not, but I get an error when my source jsp page exceed 31.7 Ko. I was not able to find a word on that special point neither on the specifications nor in JRun's documentation. I get a 500 Internal Server Error com.livesoftware.jsp.JSPServlet javax.servlet.ServletException In fact, the java file generated by JRun is empty, and this occurs only when the jsp file >= 32.8 Ko I don't know either if it is a limitation of JRun or of the JSP itself. There might also be a parameter to set to increase the size of the input buffer of the servlet server, but I didn't find where, if it does exist. Any help would be appreciated. Thanks Sylvain

Again on Threads
Thanks for your answer, but now I'm a little bit confused. My new questions are: 1) Is 5 the number of threads for every istance of a Servlet in memory? Example: I have 4 Servlets istantiated -> does this mean that the maximum number of threads is 20? 2) Which is the maximum number of servlets that could be simultaneously istantiated in memory? Is this dependent from the Web Server or the Application Server or whatever?
