Re: latest production version?
[D. Akers] Could someone please tell me which version of orion is the current reccommended version for implementation? We have been using 1.4.5 for development but need to do an implementation for a client. Which version is best (ie most stable, tested, "official" release, etc) for full-scale deployment situations? Since orionserver.com says "Stable version: 1.4.5", I'd go with that. After all, if 1.4.7 (or whatever it's at now) were deemed stable enough, the web site would (or at least, should) reflect it as the new Stable.

Re: Error unpacking: IO Error: error in opening
[Randahl Fink Isaksen] I am wondering if I am the the only one getting an error when deploying a new .ear (this happens often but not always): Auto-unpacking C:\(...)\project.ear... Error unpacking: IO Error: error in opening zip file Does anybody know why this happens, and is there a work-around apart from restarting Orion? I've seen this mainly when Orion doesn't wait long enough and tries to open an .ear file before it's fully copied-over from another location. The quick fix is to re-try the transfer. It's not an "easy" problem per-se, but polling on file size when the time/date stamp changes and extracing when the filesize is the same (and is non-zero) for 2 consecutive checks is a method I used to use that worked well. Yes, it's a heuristic. But, yes, it's better than what's there now :) For "most" people, the transfer is fast enough once you're overwriting the .ear to where it's not a big deal. You can workaround by transferring into a tmp file and doing a rename (or 2 renames, at most) How to treat this can lead to a religious war, which is why I've kept from bringing it up in the past.

auto-deploying without editing config/*.xml
I asked this once before as part of another thread and didn't get an answer, so I'll try in a new thread :) The feature I like about jBoss the most is the auto-deploy directory where i can just drop in a .war/.ear/.jar and it gets deployed as per the xml files already in the file. From what I've seen, if you're using Orion you're forced to edit config/server.xml and config/default-web-site.xml for the application, and then the webapp inside it, to be deployed. Is this correct? If not (I hope :), how can I setup such a dir? (or at least not have to edit config/default-web-site.xml on each new webapp). FWIW, this is mainly for a mass-migration of webapps off of tomcat :) James -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: embedded servlet tag
[Gerald Gutierrez] What would this do? There is the include tag that lets you include the output of a servlet in another. jsp:include page="..."/ this is a run-time include and an include directive for "verbatim" include of another JSP page: %@ include file="..."% this is a compile-time include This may, in fact, be the same thing you were saying... just wanted to clarify :) -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: novice question
[Kevin Duffey] in server.xml, point the application to the .war file directly. when I did that, it still looked for the META-INF/application.xml of an .ear file, instead of just using the WEB-INF/web.xml of a web app. Error instantiating application at file:/home/jmm/reporting-new.war: Unable to find/read assembly info for /home/jmm/reporting-new (META-INF/application.xml) -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Forte support for EJB programming?
[PHiL] We use FORTE for programming, J2EERI for create the .EAR of the application and the "clients" file. Those 2 archives just need to be copied in 2 folder for Orion (3 secondes...) and are fully deployed by the autodetect feature. I haven't found any capability in Forte for doing EJB skeletons, similar to EJBMaker of Orion... does such a capability exist? I know this is a little off-topic for this list, but people using Forte and Orion would seem to be best for answering this question :) -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
stored procedures and entity beans
I'm in the position of trying to migrate towards a j2ee/ejb architecture from one where most of the access logic (and to an extent, business methods) were in stored PL/SQL procedures in an Oracle 8i database. To keep from having to "reinvent the wheel"s of the stored procedures (and making the transition easier), are there any existing patterns or methods for utilizing stored procedures but still using EJB's? Is the answer simply "use BMP, put the stored procedures in load/store"? is there any orion-specific trick of defining a _query but using a stored procedure instead (can orion fetch from out variables instead of resultset?

Re: Distributed Transaction without EJB.
[Scott Stirling] JTS is not officially part of J2EE, so I haven't had to deal with it personally. http://java.sun.com/j2ee/transactions.html This page seems to imply JTS and JTA are both included, esp. since they specifically say that they're RI includes a transaction manager that supports both JTS and JTA... am I missing something? -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: Faster encryption
[David Ekholm] Is there a faster implementation of SSL for Java/Orion out there, maybe a native code solution? Or is the standard encryption package already using native code for the most critical sections? I guess not, as I have used C++ packages for encryption previously and not noticed such CPU eating behaviour. I've heard of ppl using openssl-based native code solutions, but SSLava with hooks into native calls to dedicated encryption cards/devices is going to make more sense for bigger sites (like Intel :) -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: Changing Orion Generated SQL
[Jeff Schnitzer] Take a look at the documentation for orion-ejb-jar.xml. It's a lot easier if you have a few samples to look at alongside. http://www.orionserver.com/docs/orion-ejb-jar.xml.html What changes you have in mind? For more performance-intensive entity beans attached to larger tables, it could be nice to be able add in the "hints" recognized by your particular DB (like specifying degree of parallelism in the use of oracle's parallel query in an ejb finder) This make sense? Seems doable? -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: Changing Orion Generated SQL
[Boris Gertsberg] You can't. ejbStore runs a trivial update statement. If you need to do something special you have to use bean managed persistence. My understanding was that with EJB 2.0, we write the abstract class with no properties (just getters/setters), Orion makes a concrete java source file, filling in necessary logic, then a final compilation phase to produce a first, initial, working class file. That would seem to provide an opportunity for modifying the source and recompiling to provide tweaks. What about this is wrong? -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
Re: Content-Length errors thrown when attempting to forward to a page
[Mike Atkin]
Our development team has been occasionally seeing the following error
(listed below) thrown from Orion. This happens when our application
I had a similar problem when using response.sendRedirect(). I don't know
whether the same applies to you, but in our our code we had a section like:
% if( some_condition )
response.sendRedirect(another_url);
%
html stuff
oh good point... Now I've been *told* (and no, haven't looked it
up in jsp 1.1 spec like I should :) that once the jsp:forward is called,
no further processing of the current page is allowed to occur, the
forwarded page has to start processing.
Of course, my reference to Location: 302 in my last message obviously was
confused since that's a browser-level redirection (response.sendRedirect,
as you've shown).
This makes more sense (in the buffer-overflow situation), since
the forwarding itself has nothing to do with the headers (since it's
server-side forwarding, not client-side), and hence the content-length
commit is very likely to have happened.
If this turns out to be the problem, it'll be interesting to note that
Tomcat catches the problem and returns "Response already committed"
(although that was still something I had to look up in its faq-o-matic
to figure out what was really going on), where Orion's a little (but not
much) less graceful.
If the above example is changed to
% if( some_condition )
{
response.sendRedirect(another_url);
return;
}
%
html stuff
I even do the "return;" after jsp:forward's, even though I have a sneaking
suspicion that it's redundant and that I could dig and find the part of
the spec that guaranteed no further processing of the forward-source page.
Thanks, Mike!

Re: Content-Length errors thrown when attempting to forward to a page
[Roy, Jaideep] Our development team has been occasionally seeing the following error (listed below) thrown from Orion. This happens when our application running under Orion throws an error and attempts to forward to our custom error JSP page. The error happens sporadically and cannot be recreated consistently, but tends to bring the server down (i.e. accepts no more connections/requests). Also, the browser never gets a response back from the server. This has also been reported by some other users in the orion-interest archives. warning: most likely irrelevant. My experience with tomcat has shown a similar situation with forwarding whenever the attempted forward occurs (in runtime) after the point where the jsp engine has hit the buffer size and had to flush out the http headers and the first buffer of content. Solutions were to do forwarding logic earlier (before most of the html), or make the buffer size bigger (%@ page buffer=64KB % or something similar) Any ideas as to what could cause this problem? Root cause is; java.lang.IllegalArgumentException: Attempted to write longer than Content-Length (5316 + 3607 / 5316) The issue is that once you hit the buffer, the headers have to get committed, and you can't do a Location: 302 (or whatever it is) for the redirection. What's more interesting is that it looks like the forward may have completed here (in some sense) but the content-length header had already been committed, and when you resulting page is longer, an exception is thrown. Wish I could be of more help... I'd love to hear what the answer is :) James -- James Manning [EMAIL PROTECTED] GPG Key fingerprint = B913 2FBD 14A9 CE18 B2B7 9C8E A0BF B026 EEBB F6E4
