Re: ANSWER: How to use pooled connections in Orion?
Per the thread below, I realize after a bunch of tinkering that my
underlying assumption of a distributed app architecture is wrong; Orion
is managing DataSources itself, without talking to an external directory
server or other networked resource. Duh.
But, that's not what I want. What I'm after is to retrieve DataSources
from an LDAP server acting as a shared resource on the network. This
can be done manually by binding DataSource objects to LDAP independently
of Orion, then programmatically creating InitialDirContexts with
appropriate connection parameters inside my application code. What
might be better though would be if Orion's JNDI "data store" could be
configured to use networked LDAP instead of it's internal mechanism.
Can it? Can Orion parse a JNDI.xml file or equivalent? I'm not exactly
sure at this hour which approach might be more portable; the manual
version is obviously more work.

Thank you Al.
I realize I haven't worded my question correctly, though. Maybe a
better way to say it is, where is Orion's JNDI environment defined?
That is, how does Orion know the location of the LDAP server on the
network, plus the binding (login) credentials required so that the
data-sources.xml example can work its auto-magic?
If I were doing this programmatically I'd create an InitialDirContext
parameterized with a Hashtable of connection parameters. Presumably
Orion does the same thing behind the scenes. Where are those connection
parameters defined to Orion?
Many thanks,

Orion will bind the Datasource to the JNDI environment for you, you set
this
up in the data-sources.xml file. for instance for my Oracle instance the
file is ... defined in data-sources.xml like so
?xml version="1.0"?
!DOCTYPE data-sources PUBLIC "Orion data-sources"
"http://www.orionserver.com/dtds/data-sources.dtd"
data-sources
!--
An example/default DataSource that uses an ordinary
JDBC-driver (in this case hsql) to create the connections.
This tag creates all the needed kinds
of data-sources, transactional, pooled and EJB-aware sources.
The source generally used in application code is the "EJB"
one - it provides transactional safety and connection pooling.

this will bind my DataSource to "java:comp/env/jdbc/RedbookDS"

Deepak et al:
I'm confused about how Orion populates the JNDI server with the
DataSource object. Obviously for the code fragment you posted to
work,
an object "jdbc/SQLServerDS" has to exist in your directory server.
How
does it get there?
I would have guessed that admin.jar -installDataSource was the answer,
but I find no switch there which would tell Orion how to find the
directory server.
Many thanks for your posts, they're very helpful!

Hi,
The way you access the datasource is dependent on where will you
access
the
datasource from. I'm currently accessing the datasource from a servlet
which
is pretty straightforward:
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/SQLServerDS");
The above method might not be portable but it works for me so I
mention
it.
Note that you don't need any special Orion datasource name. DataSource
is
defined in javax.sql.*
The portable way which require more work is to add the following to
your
web.xml if you access the datasource from servlets and/or JSP:
context-param
param-namemyDS/param-name
param-valuejdbc/SQLServerDS/param-value
/context-param
resource-ref
descriptionA data source/description
res-ref-namemyDS/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authCONTAINER/res-auth
/resource-ref
Now, you can access the datasource by:
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/myDS");

RE: Orion in production
nt may have better mp support, at least until linux 2.4 comes out officially, but the real issue here is probably the jvm. the jvms in linux just haven't been quite there, and surprisingly microsoft have had the fastest jvms out there for quite some time. in determining whether to run on nt or linux the question for me comes down to reliability. since sp5 nt doesn't slowdown or crash nearly as much as it used to, but i can configure a linux 2.2 box with practically no services on it except the jvm and orion, and it essentially runs well forever (or at least a few months) without trouble. it is still possible to crash nt, and i've even done so with a win2k box. there is usually so much junk on one of those boxes that you cannot get rid of. the new sun linux jvm is much faster than the old blackdown ports, and the inclusion of the hotspot server engine is pretty impressive. we've been running on linux 2-way machines (testing only) for months now--found it fast and never experienced any trouble. i cannot recommend it more.. bradley mclain --- "Holmes, George (TWIi London)" [EMAIL PROTECTED] wrote: I wasn't working on the project myself, and possibly gave a slightly mis-leading impression ;- To the best of my knowledge there were 8-12 Dual P3 500, each loaded with all the necessary EJBs, JSPs et al. and load-balanced using BIG IP from F5 Networks.

I didn't say they were completely useless, but I expected better from an appserver of that price (which for JRun is, of course, still fairly cheap).

RE: Orion in production
In general the JVM developped by SUN runs substantially quicker on Windows then on Linux. Try for instance to run HypersonicSQL in core on both platforms. As I recall the performance penalty using Linux is reduced using JVM 1.3. Another disadvantage using 1.3 Linux is that the stability of the JVM tends to be less. So much for wining about Java on Linux. The good news is that the platform itself is much more stable. My server only reboots when te power goes down. As far as I know that is still not the case using NT/Win2k. When the JVM goes down in a production environment you can have Linux automagically restart the engine, causing only a small hick-up in your service depending on the startup time of the server. Further more the security of a Linux/UNIX platform is much better, but that is probably not an essential thing when you can only access Orion on the server (and all other access is denied). In that case the security features of Orion should do the trick in general. Depending on the project (and the people to support the systems!) I would choose one or the other. I remember a previous posting with a refrence to JVM benchmarks on the list about it, but I couldn't find it anymore.

The REAL documentation problem and a SOLUTION
Your post triggered off a lightbulb - mainly because I totally agree. Allaire docs are fantastic... for about 15 minutes till you get the thing running - then you're usually pretty much on your own. Which leads me to think, maybe true quality documentation will be fastest forth coming if we can isolate the issues people are most concerned about? A FAQ if you like, with long long answers and detailed questions? So how about it fella's? If there's a long list of questions people want help with, I'm sure people will be much more forthcoming with answers...

Re: URL Pathing
Thank you very much for the response. I agree with you but for some reason it is interpreting the slash as the server document root. It only seems to do this in one section of my application. Here's the scenario. There is a point in my application where the user selects the product they wish to order from a list that is presented to them. This list is an ordinary JSP page inside the main browser window. However, once they select this product by clicking on a link, it invokes a small pop-up window which requests that they enter a quantity. Once they enter the quantity and click proceed, the child window closes and returns control to the parent window. The parent window then submits it's form to a servlet which adds the new line to the order. This servlet then redirects the user to a jsp page to display the new line. Inside that servlet and the JSP page it presents, all links and redirects that contain the '/' attempt to send you to the server document root. It seems that whatever is called in relation to the child window that was invoked attempts to reference the '/' as the server document root. I hope this could provide some direction into this issue. Thanks again, Andy

RE: Orion in production
snip/ I remember a previous posting with a refrence to JVM benchmarks on the list about it, but I couldn't find it anymore. http://www.volano.com/report.html you see that speed is not so much an issue rather than scalability. for many people's requirements, however, I don't think those problems are relevant (how many of us have 2000 concurrent connections?). we haven't had any serious problems with sun1.3 on linux (hot spot server) and it's really fast enough. I'll gladly trade 5% speed penalty for the overall stability, maintainability and flexibility of a linux server as a deployment platform. robert Frank (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

Absolute path confusion
Heya, all. Yet another question on Orion config that the docs don't address (or have hidden in complete obscurity). I have a webapp which I have installed in $ORION_HOME/applications/twsm. This should be the root for all documents for this webapp. I have several subdirectories underneath twsm, such as login, images, support, etc. Each of the pages makes various calls to the /images directory. Sometimes it's a relative link (IMG SRC="images") and sometimes it's absolute (IMG SRC="/images/"). Whenever I run the app under Orion, it can never find any of the absolute links. I've tried to remedy this problem by putting a virtual-directory tag in the orion-web.xml (or orion-application.xml, whichever file this applies to) and that didn't seem to fix it. I also tried making another context-mapping in the server.xml file, which didn't work. Setting the document-root option in orion-web.xml totally hosed the app. So, the QUESTION is: What do I need to do to make "/images/..." accessible to each and every page in my webapp, no matter where it is in the hierarchy?

RE: Orion in production
Does anybody have any definitive numbers on this? What about Volano? I typically have found that for small-scale applications, I often get faster performance with the Windows JVMs (much to my chagrin ;^). For example, I almost never run Forte CE under Linux or even Solaris. It's not until you really start cranking up the application that you start to see a difference, in terms of performance under high loads and scalability. As far as Linux and Java 2 goes, Sun's 1.3 implementation was the first real performer, although it looks like Blackdown's beta appears to be giving Sun a run for its money (especially with AWT and Swing applications - Blackdown wins, hands-down). Even though IBM looks like it has another performance leader in its 1.3 implementation, it looks rather buggy and unstable at this point. Thoughts? -Rich --- Russ White [EMAIL PROTECTED] wrote: Indeed with most JVM version the NT/W2K version will be faster than Linux.

Re: URL Pathing
Andy, Forgive me if I'm insulting your intelligence by mentioning this. I discovered while using Tomcat that I had to distingush URL paths used in jsp:include tags (RequestDispatcher.include() calls) and jsp:forward tags (RequestDispatcher.forward() calls) from URL paths used in generated HTML pages. The former were being interpreted relative to the servlet context, whereas the latter were not. Therefore a "/" in a generated HTML page ends up being interpreted relative to server root. Troy [EMAIL PROTECTED] wrote: Thank you very much for the response. I agree with you but for some reason it is interpreting the slash as the server document root. It only seems to do this in one section of my application. Here's the scenario. There is a point in my application where the user selects the product they wish to order from a list that is presented to them. This list is an ordinary JSP page inside the main browser window. However, once they select this product by clicking on a link, it invokes a small pop-up window which requests that they enter a quantity. Once they enter the quantity and click proceed, the child window closes and returns control to the parent window. The parent window then submits it's form to a servlet which adds the new line to the order. This servlet then redirects the user to a jsp page to display the new line. Inside that servlet and the JSP page it presents, all links and redirects that contain the '/' attempt to send you to the server document root. It seems that whatever is called in relation to the child window that was invoked attempts to reference the '/' as the server document root. I hope this could provide some direction into this issue. Thanks again, Andy

RE: Orion in production - Let's sell support!
Tim has brought up an interesting point. Orion has granted free licenses to developers, which is a good concept. However, Orion not only has to compete with other commercial products like web-logic, but good open source EJB servers, like JBoss and JOnAS. It would only be fair to have good documentation to review, and to deploy a test sample to demonstrate Orion can work, for those funding the development and software purchases. -Original Message- From: Tim Drury [mailto:[EMAIL PROTECTED]] Sent: Monday, October 23, 2000 9:10 AM To: Orion-Interest Subject: RE: Orion in production - Let's sell support!

Servlet/EJB Connections
I am experiencing some problems with the username and password passed to EJBs running under orion from a servlet. Without a servlet, a test program can connect to an EJB through Orion and the username and password (principal/credential) are passed correctly. It seems that once the servlet tries to do the same thing, it cannot. It seems as though the servlet always sends the 'guest' account back to the EJB (when both are running under Orion) no matter what I set the principals/credentials as. This is likely a setup issue, but I haven't a clue what to look at. The documentation doesn't describe these issues which are imperitive to my success! What difference should there be between a program running on the host system and the servlet, in terms of executing a session bean? Intuitively, there shouldn't be a difference. But I am seeing differences! I have also been informed that orion will cache the username and password unless a certain property is set. The property, as I was told, is "dedicated.connection" and it must be set to "true" however, this does not seem to work. Please help.

Re: Data Sources Help
Gary, I'm running 1.3.8.
Per your research into the Orion JNDI namespace, could there be an
undocumented quirk in Orion's implementation? I've been using JNDI/LDAP
pretty extensively the last couple months and have been super impressed
with its ease and speed. But, that environment is under my programmatic
control, including the namespace design. In fact what I'd really like
to be able to do is throw a configuration switch enabling a networked
LDAP server as an alternative to using the Orion JNDI namespace. If
there were a JNDI.xml file or something like that, perhaps it would be
possible to organize the namespace in a way that makes best sense for
your enterprise application architecture; and of course other servers
would be able to share centralized resources. To my thinking
DataSources kind of cry out for this approach. Seems to be the J2EE
"way", although, I dunno, I'm still learning.
In case it helps, below are the entries in my data-sources.xml and
web.xml files, and a code example. These are taken directly from
Deepak's earlier posts. With these I'm able to get a non-null
Connection reference from the DataSource. But note this isn't to
declare victory: still have a strange bug to figure out. My tag handler
blows up with a NullPointerException when I call
Connection.createStatement() on the Connection reference. Have no idea
if this is related to the config below, or what, but the Exception is
being caught by Orion, not by my tag handler, which at first glance
points to Orion's implementation of the pooled Connection object.
Note to Mike Cannon-Brookes: based on the quantity of questions posted
to the mailing list, I'd suggest that proper configuration of
DataSources and also the workings of the Orion JNDI namespace are two
good candidates for your super-FAQ suggestion. :-)

Hmm, I am still left wondering.. Maybe we have read different parts of the Jrun specs (ver. 3.0, yes?). I can still very well remember how I struggled with the authentication mechanism (principals.xml, etc.) for several days until I finally came across the JRun manuals. The "developing applications with JRun" PDF has 16 pages on authentication, including 5 pages on "controlling the server authentication mechanism". None of that is GUI field instructions (at best, its property files description). Those chapters are the only ones I have read, but still.. I thought I had to add this. Now, I will stop advertising JRun on this list.

I dont know what docs you have been looking at. For me, looking at the JRun 3.0 documentation makes me feel like a desert wanderer hitting an oasis. I think a nicely written, consistent, complete, tutorial-like introduction IS a real value. Now, when relating to the issues covered by the J2EE standard, I can accept that we have the spec and are excpected to read it (thoroughly and completely). But when it comes to server-specific issues, I think full, well-written docs are a must. Also, regarding the pricing issue. I dont think those management types are all that stupid. The fact that a company has 1500 employees, has a huge service force and has been in the business for a decade or more may well be worth a few bucks. Its all a matter of perspective, and there is more than one justified perspective IMO. I as a techie running a small shop am well (somewhat) able to cope with orions deficiencies (only a handful of developers, strange definition of "documentation", etc.) in favor of its qualities. But I do accept that a management type running a 300+ heads shop sees things from a different angle. I thinks it is also fair to reflect that in the pricing..

This will return about 200 records to me matching my search requirements. The search isn't very complex, neither is the data so I'm at a loss as to where my CPU cycles are going. This is my command line for coercing debuging data from Orion: $JAVA -jar -Xms64m -Xmx256m -Dnjava.library.path=$ORION_DIR -Dhttp.session.d ebug=true -Ddatasource.verbose=true -Djdbc.debug=true -Dtransaction.log="con sole" -Drmi.debug=true -Drmi.verbose=true -Dnnative.user=orion -Xdebug -Xnoa gent -Djava.compiler=NONE $ORION_DIR/orion.jar -config $ORION_DIR/config/server.xml -console2 $ORION_DIR/orion.log 21 The orion.log file seems to consist mostly of pages like this: Mon Oct 23 16:24:53 GMT+00:00 2000: 40:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:4e: started Mon Oct 23 16:24:53 GMT+00:00 2000: 40:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:4e: registered bean GBP Mon Oct 23 16:24:53 GMT+00:00 2000: 40:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:4e: commit attempt Mon Oct 23 16:24:53 GMT+00:00 2000: 40:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:4e: commit succeeded Mon Oct 23 16:24:53 GMT+00:00 2000: 41:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:5e: started Mon Oct 23 16:24:53 GMT+00:00 2000: 41:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:5e: registered bean GBP Mon Oct 23 16:24:53 GMT+00:00 2000: 41:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:5e: commit attempt Mon Oct 23 16:24:53 GMT+00:00 2000: 41:1:0:0:0:0:0:0:0:e2:0:e2:62:af:bc:5e: commit succeeded new DebugResultSet() new DebugResultSet() new DebugResultSet() new DebugResultSet() To get an idea of the size of this log, I stopped the server and browser connected to it, destroyed the log, started the server up again, connected and performed one search. This resulted in a 303883 byte file, which was 5600 lines long. Most of this output was like the block above. To me this looks like Orion's allocating and freeing massive amounts of memory and dynamically created loads of instances of the GBP bean (GBP = Great Britain Pounds, Sterling currency). Part of the search will be converting from the records native currency to Sterling, so possibly Orion's creating a new GBP bean for each and every record returned from the database. Opinions, suggestions, hints or guesses greatly appreciated. Gareth White.
RE: Orion in production - Let's sell support!
On Today, Kemp Randy-W18971 ([EMAIL PROTECTED]) wrote: Tim has brought up an interesting point. Orion has granted free licenses to developers, which is a good concept. However, Orion not only has to compete with other commercial products like web-logic, but good open source EJB servers, like JBoss and JOnAS. It would only be fair to have good documentation to review, and to deploy a test sample to demonstrate Orion can work, for those funding the development and software purchases. We bought a copy of Orion for development, figuring that given the low price and the supposed availability of support for license holders, it would be worth the cost. Unfortunately, we have received zero useful support from Orion at this point. I'm trying to figure out if I've simply asked lousy/dumb questions, or if there really is zero support. Kinda hard to tell... Documenting something as complex as a J2EE server must be a daunting task, and I can't blame Orion for having trouble doing it. And even email support eats time like crazy. I suppose that's why it costs so much to buy the upscale servers, because they have the resources to provide documentation and real support. I still plan on working with Orion as long as I can stand the pain and can accomplish the job. I'm sure not tying myself to it though, knowing that any day I can run into a problem for which I might never find an answer. At that point we'll be forced to shovel out the bucks for a more customer-friendly server. Ah well, Gary Shea iTransact.com, Inc.

EJB 2.0 Dependent bidirectional relationships not working
Hi All... As I mentioned in an earlier message, I have some working example code that has an EJB 2.0 CMP entity bean working with both one-to-one and one-to-many unidirectional relationships. Next, I want to change the one-to-many relationship to be bidirectional. I expected this to be a simple change, but it didn't work out that way. I see that the ATM example does not include a dependent object with a bidirectional relationship, so I'm wondering if thie feature is known to work or not. If no one here has used this feature successfully, I'll add a bug report to bugzilla, but I wanted to make sure I did everything right first. To make my changes, I added abstract set/get methods to the dependent object class (EmailDO.java)for the remote interface of the EB it should refer to (Person.java). I also modified the deployment descriptor to have a CMR field in the dependent relationship section and a CMP field in the dependent section. I realize that the presence of the CMP-FIELD tag violates the spec, but Orion will not deploy dependent objects without it (it complaines that it can't instansiate an abstract class that it had generated). It all now looks like the Order-Lineitem example in the PD1 spec. After Orion deployed the app, I ran it and looked at the database. Orion had correctly created a table to hold the dependent (since its a many it needs its own table), but the field for the Person EB remote interface (which is the EB that the dependent is created by and should refer to) was named VALUEPERSON and had null as its value. This seems to indicate that Orion is not understanding that this field is supposed to be a CMR field. I reviewed the spec and there is no requirement that I manually set the Person remote interface in the dependent object, but I doubt thats the problem anyhow, since Orion named the person field "valueperson", indicating it thinks person is just another CMP field. Anyhow, I think I did everything right and I posted the code below. If someone sees something wrong or has any suggestions as to what I should try, I would appreciate you correcting me.

Re: Data Sources Help
Thanks Allen.
The answers to your questions are yes, and yes. Earlier messages in
this thread contained complete listings for the data-sources.xml and
web.xml files, plus a code snippet. I'll append them to this reply in
case they're helpful.
You'll note that the data-sources definitions are slightly different
than what you suggest below. Your suggestion is similar to the first
half of Deepak's example, that is, what he considers to be a non-pooled
version. After reading your message I tried it with your configuration
and the test tag handler blows up in exactly the same spot.

Excerpted from thread history:
Gary, I'm running 1.3.8.
Per your research into the Orion JNDI namespace, could there be an
undocumented quirk in Orion's implementation? I've been using JNDI/LDAP
pretty extensively the last couple months and have been super impressed
with its ease and speed. But, that environment is under my programmatic
control, including the namespace design. In fact what I'd really like
to be able to do is throw a configuration switch enabling a networked
LDAP server as an alternative to using the Orion JNDI namespace. If
there were a JNDI.xml file or something like that, perhaps it would be
possible to organize the namespace in a way that makes best sense for
your enterprise application architecture; and of course other servers
would be able to share centralized resources. To my thinking
DataSources kind of cry out for this approach. Seems to be the J2EE
"way", although, I dunno, I'm still learning.
In case it helps, below are the entries in my data-sources.xml and
web.xml files, and a code example. These are taken directly from
Deepak's earlier posts. With these I'm able to get a non-null
Connection reference from the DataSource. But note this isn't to
declare victory: still have a strange bug to figure out. My tag handler
blows up with a NullPointerException when I call
Connection.createStatement() on the Connection reference. Have no idea
if this is related to the config below, or what, but the Exception is
being caught by Orion, not by my tag handler, which at first glance
points to Orion's implementation of the pooled Connection object.
Note to Mike Cannon-Brookes: based on the quantity of questions posted
to the mailing list, I'd suggest that proper configuration of
DataSources and also the workings of the Orion JNDI namespace are two
good candidates for your super-FAQ suggestion. :-)

Mark, what version of Orion are you using? I wrote a little utility
that traverses the JNDI namespace, just looking for Context objects
and displaying what's in them. I found an env Context but it was
empty! I did eventually discover, due to a chance remark of someone

RE: EJB Problem
I have looked into it further and thought it was a missing ejb-link tag in web.xml to no avail. I have noticed that the ejb-ref-mapping tags are being created by Orion when it deploys the web application in the orion-web.xml file. This is a very bizarre problem for me.

HINT: One possible way to cure an internal error on deployment
Hi All... I just thought I would put this out in case anyone finds it usefull to tuck away for future use. For about an hour now, I have been getting an "Internal error" on deployment. The error complained that the persistence type was not set for one of my fields in an EB that participated in an EJB 2.0 CMP relationship. I don't know what made me do it, but I went over to application-deploymnts and blew away the entire application folder. Then I started Orion and the app deployed like a champ. If I could reproduce this, I would bugzilla it, but I can't, so I'm just offering this hint. Jim
Creating EAR Files

Re: Creating EAR Files
Santosh, if your using the exact same source and descriptor files from the primer, the error is most likely the location of everything in the archive. I would suggest that you use some zip tool to examint the archive built by the ant file and aloso your own to see how they differ. Once you figure out how ti use the service console to make your archive look like the one built by ant, you'll be in business. Good luck.
