RE: default.jsp bug (duplicate requests)
If I were to guess your problem is not with orion, but rather with your settings for cache expiration in the JSP pages. response.setDateHeader (Expires, 1); //prevents caching at the proxy Try replacing your cache prevention section with: % response.setHeader(Pragma, No-cache); response.setHeader(Cache-Control, no-cache); response.setDateHeader(Expires, 0); % or try removing it totally to confirm the error and set the browser to check for new pages on every hit at the client side. Regards, Manuel -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Robert Johnson Sent: Monday, April 01, 2002 7:00 AM To: Orion-Interest Subject: default.jsp bug (duplicate requests) I have discovered a bug with orion after enabling Content Advisor in both IE 5.5 and 6.0. The problem is that the default.jsp is being executed after every request, causing a duplicate erroneous request. I have created a simple test to duplicate the problem. I tested 1.5.2 and 1.5.4 which both have the problem. I also tested oc4j 1.0.2.2.1 which works fine. Below are the steps to reproduce the problem. 1. Create a default.jsp which contains the following lines: (The first few lines are to prevent caching): % response.setHeader(Cache-Control,no-store); //HTTP 1.1 response.setHeader(Pragma,no-cache); //HTTP 1.0 response.setDateHeader (Expires, 1); //prevents caching at the proxy server % %! static int x = 0; % % System.out.println(EXECUTING DEFAULT.JSP: x= + x);% %=This is default.jsp: x= + x++% 2. Create a test.jsp which contains the following lines (The first few lines are to prevent caching): % response.setHeader(Cache-Control,no-store); //HTTP 1.1 response.setHeader(Pragma,no-cache); //HTTP 1.0 response.setDateHeader (Expires, 1); //prevents caching at the proxy server % %! static int y = 0; % % System.out.println(EXECUTING TEST.JSP: y= + y);% %=This is test.jsp: y= + y++% 3. Place both files in the default-web-app folder (be sure to rename the index.html to index1.html so the default.jsp is used). 4. Start orion and issue a request for http://localhost/test.jsp. Below is the output I receive: C:\Prog\java\orion1_5_2java -jar orion.jar Orion/1.5.2 initialized EXECUTING TEST.JSP: y=0 EXECUTING DEFAULT.JSP: x=0 -- Duplicate request 5. Now issue a request for http://localhost/. Below is the output I receive: C:\Prog\java\orion1_5_2java -jar orion.jar Orion/1.5.2 initialized EXECUTING TEST.JSP: y=0 EXECUTING DEFAULT.JSP: x=0 EXECUTING DEFAULT.JSP: x=1 EXECUTING DEFAULT.JSP: x=2 -- duplicate request This is causing some problems for my site which I am about to deploy and I have been unable to find a solution. I will probably have to switch to an alternate server if I cannot resolve the problem. Any help would be appreciated. Thanks, Robert Johnson

WG: Q: How can i turn the automatic reload of the config files off?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 hi all, i'd like to turn of the automatic reload of the following config files: - - config/server.xml - - config/application.xml I'm using orion 1.5.2 under debian-linux and every time i reconfigure/add webapps in one of the above files, orion tries to reconfigure itself, fails and instead goes down. and this in a very nasty way (i have to use kill -9 and be quite fast to find out a proc id of one of the java processes. otherwise the vm eats up all resources on the machine. i used the following vm's: blackdown, ibm and sun 1.3 interestingly, this is not a problem using win2k. orion reconfigures properly. I'd like to turn automatic reconfiguration off so i can edit the config files and afterwards run my own /etc/init.d/orion restart script. tia, jan - -- Jan Heise / Tel. +49-163-4803237 / [EMAIL PROTECTED] -BEGIN PGP SIGNATURE- Version: PGP 7.0.4 iQA/AwUBPKh/yp/YNqVvLvLkEQIGgwCeOoorJcv0FBj4a7HgAXuAYRgVYE0AoI7h XGKg6G7alvKvCQH5FuXkn2U+ =2nF7 -END PGP SIGNATURE-

I don't think -cp and -jar can be used together like that. Try just using -cp and place the .jar on the classpath. -Original Message- From: John D.

Newbie Orion question - webapp problem
I'm trying to get Orion to run a web app that's part of an ear. I made the following changes: IN SERVER.XML application name=Majordomo path=C:\orion\autodeploy\Majordomo.ear auto-start=true / IN DEFAULT-WEB-SITE.XML web-app application=Majordomo name=MajordomoWeb.war root=/MajordomoWeb / IN THE EAR'S APPLICATION.XML module web web-uriMajordomoWeb.war/web-uri context-root/MajordomoWeb/context-root /web /module But when I hit http://localhost/MajordomoWeb/index, I get a 500: Internal Server Error and I can't find any output as to what the error is in any of the log files. The EJB portion of the app, which I accessed with an Application Client, works fine. One other clue: I'm referencing other JAR files, and using the Manifest Class-Path attribute in the WAR file. I tried putting the external JAR into the /lib directory of the War, but that didn't work either. Same error. Any help here? PS the EAR deploys into Sun's RI 1.3, and also into WebSphere 4.01. It works fine there, so it must be an Orion configuration problem. --- Kenneth DeLong Senior Consultant Direct: 510-517-5839 (Cell) Fax: 972.789.1340 Valtech Technologies, Inc. 5080 Spectrum Drive Suite 1010 West Addison, Texas 75001 www.valtech.com http://www.valtech.com transforming technology skills into sustainable business value
Re: Java IDE?
Subject: Re: Java IDE? From: Vic Cekvenich [EMAIL PROTECTED] === CodeGuide v4 of Omnicore.com does the same thing and is cheaper and I think nicer. (I used Netbeans as well) VIc Robert S. Sfeir wrote: (Sorry my last message got sent before I could finish it) Ok there was a lot of talk about this IDE so I decided to go poke around and look at it. I had been using Netbeans (Forte too) for a while, but always found it to have either way too many things you can do with it, and therefore you have to spend a lot of time learning the IDE, or it's just clunky and things are not where they're supposed to be. So I downloaded the IDEA IDE, and low and behold, as advertised on this list, my productivity has jumped 10 fold. It is SO easy to use, it's a bit weird at first glance, and I actually removed it the first time then decided to try again, and wow, if you take just a couple of hours, you're totally familliar with its features and capabilities... and thank go for no weird wizards... templates are good... wizards are for 2 year olds. Here is why I liked it, and would GLADLY pay $395.00 for it. It allows you to setup multiple CVS repositories, working with Ant is amazing, when you run the ant script it allows you to expand every step and look at it and get more information about it. I am able to run the full build of my app within the IDE and I didn't have to do anything funky, or mess with classpaths it just ran. I am SO productive in this IDE I can't believe it. Further, it allows you to set ALL aspects of code style including spaces between parenthesis or brackets, line after curly bracket or not, and you can choose if you want it before an else, if else, etc... so fine tuned. This is important because sometimes developers can get sloppy. One mouse click and wham, the thing is clean and in place. besides that, you can actually write a bunch of code and then select it, and tell it to wrap it in an try/catch, or add a case and stuff like that. Same goes for getter and setter, you just select the vars you want to write get and set methods for, and in a few seconds I had more than 40 gets and sets already setup. This is a much better way to do it than any other ide. The nice thing is that there are a bunch of tabs on the side which don't intrude in your coding area unless you absolutely want to see them, and you can choose the behavior of the tabed window so it can close back up as soon as you're done, or pin it down so it's always there. What ever works for you. It also includes Refactoring, and will look through your code and allow you to optimize your imports automatically. Very nice stuff, but I didn't push that yet because I didn't have a need for it yet. I also like that it has syntax completion, but they took it to a higher level, when the syntax completion pops up and you select for example 'parseInt' it shows you the java doc for it in another popup! SO SWEET! No need to go look at the API pages or anything like that! VERY VERY COOL stuff. I am surprised that Forte won the JDJ award over this IDE... I guess because it's not free or something. This is a much much better tool. Robert S.

But this may just be a marketshare estimate and it looks like a lot of folks on this list like IDEA. We've been using JBuilder 4 Enterprise with mixed feelings and are looking at upgrading to JBuilder 6. Can any of the IDEA proponents out there summarize the major advantages of IDEA over JBuilder 6
