Using '%@ include...' is a static process. If you're using 'jsp:useBean...' in both that could be causing your problems. Also, why do you include page two into page one and then set the action to call page one again? Why not create another JSP page to process the login and then you can always do a redirect to whatever page you'd like. I'm not sure what your code looks like so it's just a guess.

RE: JSP bug in state saving
That's not what I meant. During the compile of the jsp page include files are merged into their parent file becoming one piece of static code. The jsp:usebean.. will reference the instance of the object that is defined by the id for that users session. I'm not sure what will happen or if it's even legal to have jsp:useBean... occur more than once in the source that actually gets compiled. It would help to see code snippets to ensure we're all talking about the same thing here.

RE: Multiple User Debugging Env? Doesnt' Exist?
I would agree with Darren, each developer should have their own instance of Orion Server running on their own desktop. I'm assuming their machines are big enough and if you're using any of the full featured IDE's like VisualAge, VisualCafe, or JBuilder, than they probably can handle an instance of Orion. One of the kindest things Evermind is doing is allowing developers free use of their software for development purposes. Allaire just recently announced that same approach, why, because when you the developers use your software they're most likely to recommend it's use for production. I digress, sorry. Trying to share an instance of the web server for developing servlets is futile. I've been developing enterprise applications since 1983 on my PC, some were strictly PC apps others were mainframe Cobol, and most were distributed using C/C++ and now Java. I can't imagine sharing a development environment with other developers at least not until you get to integrated testing. You'll be amazed at how the time for development actually reduces and you can end up with more features and a more solid product. If it takes someone 5 days to do something in a shared environment that would take 2 in a dedicated one, by the time the 5th day rolls around they won't feel like spending more time testing and fine tuning their piece. I think the biggest challenge will be to ensure you have someone who really understands the Orion environment, otherwise, all is lost.There area lot of developers that don't want to know how to admin apiece of software like OrionServer, they just want to be users. If that's the case, then I would think about running multiple instances of Orion on the server for each developer or teams of developers assuming you have at least one person who now becomes a dedicated admin resource. my 2 cents.

I'm coming to the same conclusion, and I would like to ask the Orion community at large, how does everyone do debugging? 1) Do you set up individual web servers for each developer, and thus use a normal debugging convention? 2) Is there any way to share a server, in particular, allow debugging by various developer of their actives, while allowing other user to work normally. I'm coming to believe this later paradigm (i.e. "2") is not ever done and is probably impractical. What environment do you have for debugging? Any comments welcomed.

To get around the issues with multiple developers, you might want to use CVS, a central "unit test" development server, and individual servers installed on each of the developers machines. Developers would check out the code to their local machine, test on their local copy of Orion (with the ability to run it in debugging mode without screwing everyone else up) and post their changes back to the unit test server to check for completeness.

All, What's going on with Evermind? I've sent messages to this list, sales, info, and support about different issues and no one has responded. I thought I remember someone saying that they were overwhelmed since returning from JavaOne and that the support situation would be resolved this week. I haven't seen it, if anything it's gotten much worse and there's been nothing but silence from the Orion team. If we knew what was happening it would minimize the frustration levels.

RE: Session time out TOOOO early!
Are you saying Orion detects changes in JSP used beans? That's great if it truly does because most jsp/servlet engines out there do Not. If the JSP page changes then it will be recompiled but that doesn't necessarily mean you'll get the new bean unless Orion has their own class-loader. The beanclass is already loaded in the JVM, not your instance but the class used for creating instances. I don't know of anyone who dynamically reloads the beans. In order to pick up the new bean the server needs to be restarted. I hope you're right because this has been a big headache in managing changes to JSP used beans. My $0.2.

Second, I'm now getting an exception thrown when sending the message to the queue, "In Read Mode" is the exception message. I'm assuming I need to add security for this resource or something along those lines. The deployment of the bean has created the orion-ejb-jar.xml and it added a persistence attribute for the queue. Can someone explain what is necessary to make use of JMS queues from EJB's? Has anyone done this yet? Orion developers? One of my objectives is to keep the ejb-jar.xml as clean/simple as possible in order to maintain portability between AppServers. So far, except for JMS, I've been able to do it.

All,
In a previous message I expressed my concern about
performance as compared with Weblogic 5.1. With
assistance
from Karl Avedal, I made some changes to my application
and
am very pleased to announce that Orion is approximately 2x
faster than Weblogic 5.1.
I wasn't using the DB connection pool and it is a pleasure
to
work with a product that does conform and support the
latest
J2EE specification.
In general, migrating from WL to Orion has been pretty
painless. Most of the changes were container specific,
config files, etc. and no code changes. The only code
changes I'm now going to make has to do with improving my
code. This exercise has identified areas that were
inefficient or were specific to WL.
BTW, my evaluation of Orion and two other Ejb servers has
resulted in Orion as my choice hands down.
Thanks

RE: Performance Scalability Concern
I
understand but if you didn't have a J2EE container how would you resolve
it?
Once
in the CLASSPATH all objects within the same JVM are effected by the order;
therefore, the idea of self-contained components break down. They're all
subject to the JVM including J2EE implementations.
Do you
really want to start dynamically loading your own specific classes via
reflection? I don't.
How
many vendors do you know even truly have as close to a full J2EE implementation
that Orion has?
JBoss
is going to rely on plug-ins so now your reliant on multiple vendors and release
schedules. Weblogic ($$$) is very very close but they fall down in some
areas as well, and IBM well.

RE: HELP: Reoccurring ArrayIndexOutOfBoundsException from Orion
I was just getting a similar error but it was due to an existing jsp page that was using a tag incorrectly. In my case they we're using %@ some java code % which Orion didn't like and it threw an out-of-bounds exception on a String. There's probably an JSP syntax error somewhere in your code. Note to Orion developers: One thing that would be more helpful, trace messages in the console window or even to a log file. Sometimes you'll get an error w/o a stack trace and all you get is an 'unable to display the page' message, not very helpful. How about msgs upon startup so we can determine what's been loaded or not, etc.. Does anyone know if tracing exists in Orion and if so, how do you turn it on?

RE: HELP: Reoccurring ArrayIndexOutOfBoundsException from Orion
Excellent! -Original Message- From: Karl Avedal [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 05, 2000 3:32 PM To: [EMAIL PROTECTED]; Orion-Interest Subject: Re: HELP: Reoccurring ArrayIndexOutOfBoundsException from Orion Hello Tom, There's an application log file written for every application. You can find it in application-deployments/myapplication/application.log (or similar depending on if you use another deployment dir and depending on your application name...) With the graphical console that is days away from a preview you'll easily see exactly what is loaded into the server, so if you can just wait a few more days... Regards, Karl Avedal Tom Wnuk wrote: I was just getting a similar error but it was due to an existing jsp page that was using a tag incorrectly. In my case they we're using %@ some java code % which Orion didn't like and it threw an out-of-bounds exception on a String. There's probably an JSP syntax error somewhere in your code.Note to Orion developers:One thing that would be more helpful, trace messages in the console window or even to a log file.

Setting library path
I've got a number of supporting classes that my ejb's need access to. I originally copied the dir structure beneath the ./lib dir and everything worked fine. I'd really like to keep it with the rest of the application but can't seem to get the server to search the CLASSPATH for these classes and I've tried setting the library path in the config/application.xml file. library path="../lib" / I'm obviously missing something simple, help!

Update: Performance Scalability
All, In a previous message I expressed my concern about performance as compared with Weblogic 5.1. With assistance from Karl Avedal, I made some changes to my application and am very pleased to announce that Orion is approximately 2x faster than Weblogic 5.1. I wasn't using the DB connection pool and it is a pleasure to work with a product that does conform and support the latest J2EE specification. In general, migrating from WL to Orion has been pretty painless. Most of the changes were container specific, config files, etc. and no code changes. The only code changes I'm now going to make has to do with improving my code. This exercise has identified areas that were inefficient or were specific to WL. BTW, my evaluation of Orion and two other Ejb servers has resulted in Orion as my choice hands down. Thanks Tom Tom Wnuk [EMAIL PROTECTED] [EMAIL PROTECTED] winmail.dat
XML Parser
It appears that the default parser is from Sun. I'd like to use xerces xalan for my XML management. There are methods such as normalize() which only exist with DOM 2 and are not present in Sun's parser. I'm also using importNode which I'd guess is also missing. I have updated the xerces xalan jars that are distributed with the latest version. Is it possible to Not use Sun's parser and specify xerces?
