Re: OR mapping with Oracle
You can use complex OR mapping with orion, for instance if you have an compound PK object you can map all its fields to different columns in the database table See orionsupport - complex or mapping http://www.orionsupport.com/articles/complex-or.html - Original Message - From: "Hegyi Tibor" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Monday, December 04, 2000 7:46 AM Subject: RE: OR mapping with Oracle Thanks for your reply.

Subject: Problem with synchronized method
We are using Orion 1.4.0 with Sun VM on Windows 2000. We use JBuilder 4.0
IDE.
I've put together a simple test for using custom JSP tags to perform
language translation. We are using a hashtable to hold the translations
that the tag handler class will look up. That hashtable is stored in an
application variable. However, the hashtable is not created until the
first time a JSP page calls the tag handler, at which time a call is made
to a synchronized static method to load the hashtable (from EJBs), and
store it in the application variable.
I'm using a testing tool to hit the page with multiple simultaneous
threads, and the program works perfectly upon initial start-up of Orion:
the first thread to hit the page goes into the synchronized method to
create the hashtable, and all subsequent threads wait until the first
thread is finished. Upon entering the method, there is another check to
see if the hashtable has been created so subsequent threads won't
re-create it.
However, the JSP page I'm hitting is cached in a sub-directory within the
orion root directory. If I shut down Orion, then re-start it (thus
clearing out the application variable), the synchronized method is no
longer "obeyed" if that cache is present -- all threads immediately enter
the method and begin building the hashtable.
If I delete the cache file (it follows a *.jsp.jspCache naming
convention), and then restart Orion, the synchronized method works
correctly again.
What am I doing wrong? What does the cached jsp page have to do with my
static synchronized method working correctly?
Attached is the java class LTTagHandler. It contains the following
method:
private static synchronized void createDictionary(PageContext pc){...}
which calls another class to buld the hashtable (I assume the other class
is irrelevant in this situation). I hope it helps...
LTTagHandler.java
If anything here is unclear, please e-mail me. We would like to find a
solution to this problem as well as figure out how orion is handling these
requests to the tag library.

FORM login with FRAMES
Hi there We would like to use FORM login/authentication with our web app that uses FRAMES and JavaScript extensively - example one frame will call a dynamically generated FRAMESET that loads different documents depending on the situation, while Onload events reloads contents of other frames. Out problem is when the session expires or for some other reason the webapp wants to re-authenticate the browsing user. So what happens.. a login page gets loaded into each and every frame window. We've tried redirects, forwards and some javascript. But it seems like orion likes to keep everything to only one frameless page. What can we do? Kind regards Theo van Niekerk

ORMI: changing username, password Client Context properties
Hi there It seems like once a client app has established a jndi-connection with the ejb-container through ormi that it can't change the user,password properties for the lifetime of the VM. I've tried resetting properties, closing/unbinding connections and creating new intances of InitialContext. The requirement was for a daemon to pop XML documents as email, parse it and use the auithentication info in it to connect and do transactions. I've solved it by using the os (Debian) daemon processes - so I can start a new VM instance for every email. But that's not very optimal. I appreciate any help Kind regards Theo
Orion UserManager and ejbPostCreate
Hi there We're getting a deadlock during the creation of a UserBean. We're using the Orion UserManager. In the ejbPostCreate Method of the UserBean we do a.. User caller = userhome.findByUsername(context.getCallerPrincipal().getName()); ..that causes the freeze. The reason for the post create is that we're doing a.. User new_user = (User) context.getEJBObject(); ..a few lines down and this info should (only) be accessible once the bean has bean created if we understand the Spec. correctly. Now for some reason if we put this lines of code in a private method and call this private method from within the ejbCreate method it works. Kind regards Theo van Niekerk
Class-Cast-Exception Error
Hi, I have a Web application with forms. A servlet updates a database on behalf of a JSP. It worked okay until today when some one in my company tried to fill and submit one of the forms. He got a class-cast Exception. I was amazed because that had never happened. I tried it myself and got the same error. I was certain that my application was okay since it had run a couple of other times without errors. I stopped Orion and restarted it and the error disappeared! Strange I must say.

Hello Alexander, if you want to use an EJB named Account you should have the following classes: - AccountBean (extending EJBUserBean), - Account (extending EJBUser), - AccountHome (extending EJBHome, you have to copy all the definitions from EJBUserHome modifying the return type, and optionally can add other finders).

Traversing JNDI namespace
Hi,
How can I find what's in an entity bean's java:comp/env namespace?
If I ask the InitialContext for a list of what is in it (using
initialcontext.list("") ) I get a list of things (mainly home interfaces)
plus entries for "java:comp" and "ejb" which are both Contexts.
If I ask for what's in "java:comp" I get a few strange entries, but NOT one
for "env", which is the one I would have expected.
If I ask for what's in "java:comp/env" I get nothing back (empty context).
However, lookups for entries named java:comp/env/foo succeed where they should.
Any ideas?
Thanks,
Nick
Re: Where is Orion's copy of ejb-jar dtd?
I got it work :)
The short hint: check that every method you invoke exists and your JSP
syntax.
The long story
==
1. I started using Orion and built an application that simply sniffes the
user name and roles using an EJB named SecuritySniffer.
2. On deployment, I got an error similar to that one:
Error loading package at
file:/C:/@web/ClassNotes/EjbJmsJndi/@StudentEjbApp/, Error parsing META-INF
/ejb-jar.xml in C:\@web\ClassNotes\EjbJmsJndi\@StudentEjbApp: Fatal error
at
line 377: Character conversion error: "Unconvertible UTF-8 character
beginning with 0x91" (line number may be too low).
3. After surfing a lot the mails about that same error,
4. I left Orion sleep for one week,
5. also renamed its directory
6. Today I tested my application again and finally got the correct error
message:
...about the invocation - from a JSP - of an EJB method that did not
exist.
7. After correcting the method invocation, everything went fine.
It seems that Orion is very sensible to little errors,
and it does not inform - or erroneously informs - about errors.
Each time I have had a strange error ("...but everything should work ?!"),
such as "The page cannot be displayed" or the one above,
the real error was of syntactical nature, and in general in my JSP;
ranging from malformed JSP, or bad imports, or non existing methods, etc.
As a rule of thumb:
If everything should work correctly and is correctly configured and it does
not,
have a look at your code, you probably made a too evident error (names
confusion, tags not closed, etc.)
Cheers

onMessage()
Hi! I'm testing Orion 1.4 JMS coffeemaker demo. The demo runs fine. I modified it to use onMessage() instead of pooling using QueueReceiver.receive() method. This however, renders this demo useless. onMessage() is not triggered. It is my logic fault or Orion doesn't support onMessage() trigger? Please refer to file provided. thank you. /lim/ CoffeeMaker.java
Re: Traversing JNDI namespace
Hi,
(And I preface this with 'as I understand it')
First, it's the app server's context, not the bean's. What parts of it you
get to see are determined by the principal/credential pair (and the roles
they connect you to, as defined on the app server) that you pass to the
context factory when you ask for the initial context.
Why you don't see what you expect in the context is another matter. May I
recommend an open-source tool I wrote
(http://sourceforge.net/projects/ejbvoyager). It will allow you to browse
your app server's context tree.
What I suspect is happening is that you are calling Context.lookup() or
.listBindings() with bad path values. Try passing both absolute and
relative JNDI paths and see what happens. Correlate this with the
.isRelative() values for the bindings you examine.
