Where are my tomcat icons in Eclipse 3.1? How to use Tomcat with Maven and Eclipse 3.1?
Is there a more appropriate place to ask questions on tomcat and eclipse? I googled for some eclipse forums and found some, but they would not let me post to them. Anyway, I noticed that eclipse 3.0.1 has some nice little icons for starting and stopping eclipse. Under preferences it also has an entry for tomcat. Both these icons/buttons and the tree control entry under preferences are missing in Eclipse 3.1. This makes it very difficult to follow the tutorial on using maven with eclipse at http://www.eclipse.org/webtools/jst/components/j2ee/scenarios/MavenEclipseIn tegration.html . Can anyone tell me how to get these features in eclipse 3.1? Thanks, Siegfried

Datasource works in Tomcat 5.5.4 but not 5.5.9

Re: newbie can't start tomcat
It may not be the best solution because you may have a special attachment to Java 1.4 but since you are running Solaris you can install JDK 1.5 anywhere (even /export/home) without it colliding with the overall SO Java installation. So why not use JDK 1.5, set your JAVA_HOME to your new Java directory and enjoy the weekend? I have Tomcat 5.5.4 running with JDK 1.5.02 on Solaris 9 and it worked basically "out of the box" doing nothing more than setting JAVA_HOME & CATALINA_HOME =) --- Luis dsimmons wrote: I have been googling the archives and anyplace else I can think of for my particular problem, for about three days, without success.

re: is this issue in the faq still correct wrt Tomcat 5.5.9?

Re: Silent runtime replace of a class
Thanky you very much, for your long answer. It seems, your theory is absolutely correct, I even found an article with detailed information about setting up a high availability Tomcat; here it is: http://www.javaworld.com/javaworld/jw-12-2004/jw-1220-tomcat.html --robert Peter Crowther wrote: From: Gal Robert [mailto:[EMAIL PROTECTED] Often happens, that we must correct a little error in business logic. In these cases we usually patch a class file, and replace it in the application, then redeploy it. From your (and other) responses it seems, there's no correct way to do such a patch without redeploying the application. Unfortunately, I agree. On the other hand, your idea about tomcat clustering, and redirecting requests sounds quite interesting. I think, this would satisfy the above requirement. Can you give me some more information about your idea? Does it require a deep know-how? Not really, but it requires that your application has a certain feature: that users using the application are independent, or that they only interact through a common back-end system that is not part of the webapp. A bulletin board is a reasonable example: users can post, and the posts are stored in a common database. Each user accesses posts through the webapp. It wouldn't matter if each user had their own separate webapp accessing the posts; nothing would appear to change. Many applications have this feature; yours may well. By contrast, an interactive chat system that uses (say) a Map in the context to know who's online doesn't have this feature - if you separate it across two servers, each would only see half the users. The multiple-server, staged upgrade is a standard technique in high-availability systems, where you want to have more than one of everything for redundancy. I'm adapting it a little here, to fulfil your requirement of on-the-fly upgrades. No doubt others on this list can fill in more details. I should add a disclaimer: I've done this with credit-card processing systems, but not with Tomcat, so I'm speaking from theory. The above should be taken with a large pinch of NaCl until someone corroborates it for Tomcat. That said, search the archives for this list, as I recall a couple of discussions from people who had almost exactly this setup. If you have n identical nodes and a way of shifting the load away from one of them, you can produce an idle node - at which point you can upgrade it to the new version. This part requires no more than several identical Tomcat (or other servlet container) instances. For high availability, you'd run them on different machines. For high flexibility and to allow upgrades (your situation), you could choose to combine them onto one machine if you wished to take the reliability risk and understood the performance characteristics of the system. Often, it's cheaper for the business to buy another pizza-box server and shove it in the rack than it is to pay someone's time to investigate the 'cheaper' way of doing it! The new part is that you need a front-end load balancer. This can be done in hardware (Cisco's mid- and high-end routers have this facility, for example). I strongly suspect it can also be done in software; I'd be very surprised if nobody had written this into some combination of Linux kernel and modules. I don't know whether it can be done using an Apache front-end and JK; I suspect someone on this list could enlighten us. The load balancer sits 'in front of' your n identical nodes and has its own IP address, which is the IP address by which your users connect to the application. That load balancer then redirects requests to the nodes according to its policy. That policy needs to include 'sticky' sessions: a set of requests from a given user will always be directed to the same node. If your organisation has no experience of setting one of these up, you'd probably want to buy in the expertise. Now, to upgrade a node (say node B of two nodes labelled A and B), you change the load balancer's policy: existing sessions remain sticky, but all new sessions go to node A. Monitor the number of sessions on node B; when it drops to zero, it's safe to upgrade B, restart it and test it - you know that no users will come in and disturb your tests. Then change load balancer policy to send new sessions to node B, wait for all the sessions on A to complete, and do the symmetrical upgrade on A. Finally, set your load balancer policy back to even distribution if you wish to use the redundancy in this system. You can short-circuit the whole process if you don't want the redundancy: the load balancer always directs traffic to one 'current' node, and most of the time you have one 'spare' node. To upgrade, make the change on the 'spare' node and test, then change policy to make the 'spare' node receive all new sessions. Once all the sessions have finished on the old 'active' node, the roles reverse - you have a new 'active' node that's been upgrad

RE: [OT] Recommend a UK Tomcat host
Not sure if they use tomcat or not (the tomcat piccie is displayed in one of their images) but you could ask. I am not with them any more but had 1st class service while I was. http://www.positive-internet.com/products.html -Original Message- From: Mark Benussi [mailto:[EMAIL PROTECTED] Sent: 08 July 2005 09:45 To: 'Tomcat Users List' Cc: 'Struts Users Mailing List' Subject: [OT] Recommend a UK Tomcat host Apologies for the repost to the Tomcat list but I am getting desperate. Can anyone recommend a UK based Tomcat hosting solution? I have been let down by my current ISP (nameonthe.net) which has gone out of business. Your help is greatly appreciated.

I assume that logout usually goes hand in hand with a session invalidation, then Servlet 2.4. spec is your friend: SRV.10.2.1 Event Types and Listener Interfaces javax.servlet.http.HttpSessionListener Cheers, Michael > > Dongsheng Song > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: invalidated session
Yes, you shouldn't rely on finalizers to clean-up session objects. Better do it in your listener. Len Popp wrote: I'm pretty sure that the finalizers are only called when garbage collection reclaims the objects, and that will be some time after the session is invalidated. Possibly a very long time after, if Tomcat isn't busy and isn't using much memory. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
