findByPrimaryKey() calling store()
dear all,i have a jsp that calls findByPrimaryKey on an entity bean.the data that the bean represents exists in the database.it seems like ejbStore is being called as a result of callingfindByPrimaryKey.also, once i have a reference to the bean, calling an accessormethod on it also seems to cause ejbStore to be called.is there something i can set to prevent the bean beingupdated when there is no (apparent?) need, or am i missing something? thanks,greg.// as a result of findByPrimaryKeySELECT id FROM sales_order WHERE id = 5UPDATE sales_order SET notes = 'notes 5' WHERE id = 5IF @@TRANCOUNT0 COMMIT TRAN BEGIN TRAN// as a result of calling order.getNotes( ), an EJB method// that does not access the databaseUPDATE sales_order SET notes = 'notes 5' WHERE id = 5IF @@TRANCOUNT0 COMMIT TRAN BEGIN TRAN
RE: Please help! I get null pointer exception after calling createonan EB with EJB 2.0 CMP Orion 1.3.8...
I took a quick look through and noticed one thing which looks strange.
I believe that when you use a primary key class for a compound key, you
should *not* make the key class a cmp member of the EJB. Rather, the
EJB needs to have cmp fields which are named the same as the public
fields in the primary key class. The container figures out how to map
it all out.
Take a look at section 9.10.1.2 of the spec. I'm pretty sure this is
your problem.
I seem to remember one of the Orion guys mentioning that any
less-than-stellar error messages should be considered bugs to be logged
in bugzilla :-)
Good luck,
Jeff

OK, here is the code and deployment descriptor. I apologize
that there is a
lot here, but I have included one entity bean, a session bean
that creates
this entity bean, and the deployment descriptor.
Eventually I am planning to move all the address information into a
dependant object, but heck, I have to get create working first ;-)
Thanks VERY much!

Hi Jeff!
Thanks alot! I see I'm not the only one up at 4:00AM! I really, really
appreciate your help with this.
I'll look at that right away. In the meantime, I solved the problem minutes
before your email arrived. Apparently, Orion does not like for the create()
method on the bean class to not set a value for the primary key. I was
leaving them set to null, which was causing the NPE.
I replicated this in a small, simple sample that does nothing more than
have a servlet create an entity bean (in EJB 2.0, of course).
Anyhow, I don't know what the scoop on this is. I'm going to review the
spec, since I thought that was legal behavior. Then again, anything seels
legal at 4:00AM!!!
Thanks again!! I'll let you know what I figure out.
Jim

JSP-Compiled Servlets ??
hi all, Weknow that JSP are compiled into servlets. In Jrun, I canview the equivalent servlet source code for the JSP. ButOrion doesnt seem to provide the source as well as class file. All it creates is a binary jsp.Cache file. But my job is to get into the code and see how the servlet is getting written and compare with servlets generated thru other jsp-engines. What do i do?

ejbtags.jar createBean is broken
Is anyone using the ejbtags.jar kindly provided by the Orion team? I must imagine not, because createBean doesn't work without modifying the source :-) The problem is that the UseTEI variable is set to AT_BEGIN rather than AT_END, where it needs to be for the createBean tag in the useBean body to work. Are there any references to the tag libraries on the Orion site? I searched and searched but I couldn't find a link. I had to dig up a link to the correct page from one of the reviews on theserverside.com, which I only just barely remembered seeing. For anyone else who was as confused as I was, the link is http://www.orionserver.com/tags/ejbtags/ http://www.orionserver.com/tags/ejbtags/ Since I'm on the subject of taglibs, has anyone else noticed that the taglib api feels like it was designed in a big hurry? It's really akward compared to the rest of the J2EE spec. What's up with these TEI classes? Shouldn't that information be in the deployment descriptor?

Sharing Session Type Information
Hello All, I'm hoping somebody can help with this question. I've searched the list and have found several references to this problem but none that appear to work in my case. Here is the problem. I have multiple domains that all are part of the same network, including one domain that acts as my secure server, and I would like to share session information (or session type information, mainly username and a shopping cart) between them. Here is an example: www.domain1.com www.domain2.com www.domain3.com secure.domain4.com Between all the domains I want to share a username and whether or that current user is logged in for this session. I also need domains 1,2,3 to share a shopping cart with secure.domain4.com, but not with each other. Right now I have Orion configured where each domain essentially has it's own default application. I tried to setup a common default application for all of them, then use the share="true" tag, but all the domains come up to the default application root rather then the domain application required. To be honest, I'm not sure how to set it up so that a domain goes to a particular root while still having a common default application. If I knew this, the "share= true" tag might work. Maybe this is all I need to do what I want although from what I read, I'm not sure this is true. If anybody has any good ideas or a bona-fide solution, I would be extremely grateful! Thanks in advance! Respectfully, Jaymes H. Sorbel

RE: displaying xml
I'm responding to the previously included message. I have suggested that Orion look at the documentation provided by W3C, the World Wide Web Consortium, on it's Jigsaw server (which is similar in design to the Orion server). W3C is in the process of creating a three hundred or so page PDF format manual. While I don't expect Java developers to create that extensive documentation, this documentation could be farmed out to some technical writers.

Tag handler design issues concerning instance reusage
What steps might a tag handler developer need to take to avoid getting unexpected results because the container reuses tag handlers? (For example an old value for an optional attribute might still be around when the tag handler is invoked for another tag.) Should one initialize all optional attribute values somewhere? (In what method would that be?) Or should one reset all values after the tag handler is finished to give the next invocation a clean one? (This seems to imply a performance hit, small, but still there..) Best Regards, Markus -- Markus Holmberg | Give me Unix or give me a typewriter. [EMAIL PROTECTED] | http://www.freebsd.org/
support EJB2.0 or not?
When I try to write a 2.0 compliant entity bean:

public abstract void setName(String s);
public abstract String getName();

Orion throws the error (at deployment):
... Bean class com.tfc.ejb.ContactBean must not be declared

RE: findByPrimaryKey() calling store()
Have you implemented the suggestion in the FAQ and added an isModified() method to your bean?

How can I help Orion figure out that I am not changing the state and that itdoes not need to talk to the database?

Re: 2 many messages - News Server needed. - Or we could split the list
Actually, I think the mail list is fine. I use a filter to move these messages into their own folder. Good idea. However, I do feel that some improvement is possible. I recomend splitting the list into a few other lists. Yes - create 2 news groups. The main point of this is the automatic ordering of threads that this allows, in my email client at least.

RE: Cart example is not stateful!?
"Stateful" in "stateful session bean" does not mean
"persistent". What it means is that state, say your Collection, is retained in
between method calls to that session bean.
To
answer your last question, stateful session beans are not persistent because
they were not intended to be. That's what entity beans are for. Or you can add
JDBC to the SB.
Hope
this clarifies things.

We found the one with the zipped stream to be roughly 5 times faster (sorry
but we didn't take real good measurements). You can try it yourself - it's
pretty easy to do. Mind you - this is not a veyr compreehnsive test - but
the results over a 56K modem appeared quite compelling (over a !0mbit
ethernet or a T1 you don't notice that much improvement)

list archives
How can I view the list archives for reviewing the discussion on running Orion server processes as someone other then root? How do I view the list archives in general?
Re: 2 many messages - News Server needed. - Or we could split the list
IMO, the mailing list is just fine. If there are too many messages for your inbox, then you should filter it away. All the popular mail clients will handle this. I am sure I am not the only one who feels this way, nor am the only one who belongs to many other special-interest lists, all delivered via email and filtered. I belong to roughly 40 or so development lists, some of which average 40-50 messages a day. They happily get filtered away into their own folders. (In fact, I just archived my Postfix users list from the past year-- 14,000+ messages.) If the list does need to be split, it should be split by the Orion folks as they deem necessary. Please realize however, when talking about splitting the list into different development disciplines, that is no longer Orion specific, it now becomes a Java app development list-- which there are already many. If someone volunteers to setup a web-based "message board" or a separate NNTP server, then that is their perogative. But I do believe that not keeping the product support channels centralized will not only confuse the new users of Orion, but also be the cause of frustration trying to find out which method of support is actually productive.

Re: findByPrimaryKey() calling store()
thanks for the response. i checked again and i'm using BMP (attached is ejb-jar.xml). i haven't really got my head around how transactions work with entity beans although doing lots of reading at the moment. i'm thinking maybe the orion ejb container is treating each of my entity bean calls as a transaction (as supported by profiling the sql server database we're using), and that's why store is being called (?). we currently use stateless server beans, and handle connection pooling ourselves since all the ejb connection pooling stuff asn't that mature when we started our project. we're now relooking at entity beans, etc, and working out how to do all the simple things like controlling transaction boundaries, etc, and connection pooling. greg. - Original Message - From: "James Ho" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Thursday, October 19, 2000 6:04 AM Subject: Re: findByPrimaryKey() calling store() Hi Greg...

public abstract void setName(String s);
public abstract String getName();
...
}
Orion throws the error (at deployment):
... Bean class com.tfc.ejb.ContactBean must not be declared
abstract
So what did I do wrong? Does Orion 1.3.8 or 1.4.0 support
EJB 2.0 entity beans like the web page advertises or not?

Creating 2 Web-sites hosted from orion [V.Newbie]
I installed Orion - works great... but... I have been asked to create an intranet site (intranet.intaz.co.nz) and a dev site (dev.intaz.co.nz) hosted on the same machine (WinNT4). I got the initial site (dev.intaz.co.nz) working via client DNS search entry and an entry in the servers hosts file... Replaced the default-web-site folder contents with our intranet (that was living as a file:// based set of pages)... Works great... Now I have to put the dev site in for JSP/Servelet and EJB development... a) What do I have to change in NT to make the virtual host. (2 domains, 1 IP#) b) is the 'node' entry in the 'server.xml' and a second 'default-web-app.xml' file (with their respective 'virtual-hosts="blah.intaz.co.nz"' entries) all I need for the orion side of things? -- Aaron Scott-Boddendijk INTAZ Limited +64 7 838 3371 Voice +64 7 838 3372 Fax
