Re: Iplanet maximum no of session 1000
did you ever consider contacting iPlanet support for this? Looks like it's a default setting you have to override by specifying a different value. Read the manual.

Re: Servlet needs to run till the lifetime of Webserver
what do you mean by "run"? By definition, a servlet works in a request/response kind of way. If you have code that you want to run in a servlet, and you want the code to run continuously, I'd say you generate a request to the servlet at server startup, and write the servlet code so that it never completes the request. Of course, you'd have to config the server so that it doesn't timeout the request, which gets you into trouble in cases where you do want other requests to time out. Please give more insight in what it is that you're trying to do with this, so that maybe I can give more to the point advice good luck Rob Ganesh MohanRao wrote: > Hi, > > Please tell me how to make a Servlet Run till the lifetime of Webserver. > > Whenever the webserver starts, Servlet needs to start and should run till > the Webserver shuts down. > > Please help me. > > Thanx. > > Ganesh > > === > To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set JSP-INTEREST DIGEST". > Some relevant FAQs on JSP/Servlets can be found at: > > http://java.sun.com/products/jsp/faq.html > http://www.esperanto.org.nz/jsp/jspfaq.html > http://www.jguru.com/jguru/faq/faqpage.jsp?name=JSP > http://www.jguru.com/jguru/faq/faqpage.jsp?name=Servlets === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Last question
Setting in the Tomcat (?) props should do it. I would go this route unless it gives you problems, then you could hardcode it (or put the value in a properties file, load it at startup time and call setMaxInactiveInterval to set it manually). Of course, if the value has major significance for you application, I would consider not setting it in your servlet engine config, because you'd want to embed that configuration in your app explicitely (so in that case I would go the hardcoded or app properties file route). cheers Rob Marino Vittorio wrote: > Sorry aboout all the questions I am posting here but I've got a time > critical app to set up as fast as I can.

Re: Session timeout (follow-up)
actually, whether or not this works (well enough) will depend on the Servlet/JSP engine that you're running on. I know that WebLogic doesn't automatically clean up sessions right as they're invalidated, and the session doesn't start removing attributes (causing the call to your valueUnbound method) until the servlet engine decides to physically remove the session object from memory. You might need to investigate further to see how your platform influences this approach. good luck, Rob Rob van Oostrum wrote: > 1) You write a class that implements > javax.servlet.http.HttpSessionBindingListener > 2) You put your cleanup code (or the calls to your cleanup code) in the > valueUnbound method. > 3) When your session is instantiated (i.e. when the user hits the first JSP), > you create a new instance of the class you created in step 1) and you register > it with the session using the HTTPSession.setAttribute() method.

Re: Session timeout
1) You write a class that implements javax.servlet.http.HttpSessionBindingListener 2) You put your cleanup code (or the calls to your cleanup code) in the valueUnbound method. 3) When your session is instantiated (i.e. when the user hits the first JSP), you create a new instance of the class you created in step 1) and you register it with the session using the HTTPSession.setAttribute() method. The name of the attribute is trivial, assuming that your application does not need to retrieve the object for any other purpose. What this does, is that when the Session is about to be invalidated, it tries to unbind all objects that have been bound to it. If it finds that a bound object implements the HttpSessionBindingListener interface, it will call the valueUnbound() method on that object.

Re: Tomcat failed to start
So ... try to use another port (trial and error is so underappreciated as a problem solving technique). If that does work, it could mean that another application is using that port. Do you get an address in use error? Please supply more detailed information (screen output, error dump etc etc) when asking something on here. Also a lucky shot: MS Proxy Client has a tendency of causing ports to not be released properly, forcing you to reboot between 2 runs of Tomcat. -Original Message- Hi: I have been using Tomcat on Windows 98 for sometime.

I'm trying to call a JSP from a Servlet in such a way that I can catch the resulting stream for further processing. The code looks like this: URL tempURL = new URL( jspURL ); URLConnection connection = tempURL.openConnection(); connection.setDoInput( true ); InputStream xmlStream = connection.getInputStream(); It crashes on the last call (java.io.FileNotFoundException). The URL works if I just type it in manually, but the result from the JSP is an error saying that the GET methof is not supported by the URL. any suggestions?

Subject: Re: Diff. Bet. Enumeration and Array
An array is a collection of elements keyed by an index number (or, in the
case of a multi-dimensional array, multiple index numbers, one for each
dimension). Elements can be directly accessed by this index.
An Enumeration is a collection of elements specifically designed to optimize
traversing down a list of elements in optimal fashion. The Enumeration does
not know how big it is. It has a pointer which points to the current
element. The Enumeration is only able to return the next element, or tell
whether or not there is a next element. Therefor, the enumeration can only
be traversed once and is useless after that.
If you want to determine the size of an Enumeration you'll have to do
something like this:
int count=0;
while ( enum.hasMoreElements() )
{
enum.nextElement();
count++;
}
System.out.println( "Size of enum is " + count );
hope this helps

Re: forward and the URL
Actually that's not entirely true. Just have the first JSP redirect to the second one, rather than using forward. I'd do this by writing a simple Servlet with one method that only does this one call. So you inherit the JSP from the servlet and call de servlet's method from the JSP. The redirect makes it look to the webserver as if the client requested the URL. So the new URL displayed in the browser address thingy will be the URL of the second JSP.

I couldn't agree more with Paul's remark. Personally, I don't really care about the number of emails I get every day, or answering questions that wouldn't have been necessary if the asker had opened a book or read a website (although mostly I tend to ignore these). My problem with this is that you don't learn anything by asking "newbie" questions. You learn by sinking your teeth in Java or JSPs or whatever, and saving lists like this one for when you're completely lost after hacking away at a problem for 6 hours straight. Personally, I think it's a shame that so many people deprive themselves the opportunity to learn so much more by using this list as a first rather than as a last resort. If you're a total newbie, get a 21 Days book. If you're a little more advanced than that, try to find your answers in API documentation, FAQs, previous postings, etc etc etc. If you won't put in the effort to solve the problem yourself, how can you even think about asking time out of somebody else's day to help you?
