ORMI problem
Hi all, I've noticed a strange bug in our latest production environment relating to the behaviour of Orion's RMI protocol (ORMI). I'm running Orion's web containers in different network segment than Orion's ejb containers. So, the RMI traffic is going through a firewall which is between these segments. When there has been lots of idle time, the front-end web container loses the RMI connection and hangs on it without ever trying to make a new connection. Has any of you noticed similar behaviour or do you have any guesses what might be going on? Otherwise I have to set up a stupid ping application which periodically makes HTTP requests and keeps the connection alive ;) -- Joni [EMAIL PROTECTED]
Upload files
I try to upload file from a jsp-page with the code below. The code retrieve

I can not understand why? Can any of you help me with this problem or have
any of you done this?
Thanks in advance,

Resource Adapter (Connector API) - JNDI?
How (if possible), can a Resource Adapter (through the Connector API) be mapped into JNDI, in Orion? I might have overlooked something, in that case, bear with me. Markus -- Markus Holmberg | Give me Unix or give me a typewriter. [EMAIL PROTECTED] | http://www.freebsd.org/

Subject: TranSaction RequiresNew PROBLEM (follow up)
Hellu,
I have two methods A and B, and want that the Database action in method B
are rolled back when an error occures, while the database actions in
method
A are commited.
I tried this to work, but don't have much success, please some help ?
I am running on RedHat 7.0, Orion 1.5.1, Postgres 7.0
What I did:
- All methods in the EJB Session manager, have the transaction attribute
set
to RequiresNew (see below). I am using CMPG by the way.
- I throw a RemoteExcption in method B that I catch in method A, such that
the DB activities in B should be rolled-back, but not the ones in method
A.
Result: all db activities are commited !!! Also in case I throw a
EJBException instead of a RemoteException (see the test code below).
- I tried to force the roll-back in B by using the method setRollbackOnly
of
the SessionContext, just before I throw a RemoteExcption. However this
forces that ALL database activities are rolld-back.
- I tried to monitor the Orion transactions with
Dtransaction.log=console,
but this doesn't make any sense.
- Could it be that Postgres doesn't support nested transaction over the
same
connection, and that Orion uses the same connection for both transactions
??
Please some help ??

ejb calling a remote ejb
From my Orion application server I'm trying to use one ejb to call another ejb contained in a second orion container onanother machine. In all the documentations I have read that you should only sepcify the remote ejb in your ejb-jar.xml file in the tag ejb-ref. The documentation says that you should give the fully qualified name. This is persumably of the form: machine_name.sub_domain.domain/x/ What I don't know ishow x/ will be understood? How would the rmi server know wherethe starting point on the remote machine will be from which to go to x/? It seems that somewhere on the local machine (in one of the xml files) we should tell rmi where the starting point is on the remote machine. Any ideas? If you have a code and descriptor file snippet that would be appreciated. Many thanks
Re: Does anyone know how to get working Netbeans 3.2 with orion 1.5.2 todebug JSP's?
I run pretty much the same setup as you. What I've found, is that it is easier to compile the JSP under NetBeans and let it gripe about errors. Servlets and other classes are easy to debug remotely, but JSP's get compiled to servlets and then run. I have had a much tougher time debugging them interactively, and discovered by accident the JSP compile in NetBeans. I believe it uses the Tomcat JSP handler internally. I have not had any problems with it since. My initial experience was debugging JSP via IBM's VAJ environment. It was ok for debugging JSP, but it would blow up occassionally and I would have to uninstall reinstall (VAJ). I find NetBeans much more stable and reliable, even though I can not debug the JSP's directly. There may be some other way that I am missing - I keep finding neat new feature under NetBeans.

Works fine for me. Only difference is that as in the example I read directly

int character;

out.write( character );

Orion and MS Access for Demonstration
I've seen two problems that exist with using Orion/EJBs with MS Access. We're trying to use Access for a small pilot as it is easy to move around. 1) MS Access orJDBC-ODBCbridge doesn't support the primitive type long 2) MS Access or JDBC-ODBC bridge has a low limit on the size of it's "records" For the lack of long support, I map longs to ints. For the size issue, I map String types to char(128) instead of the default char(256) My question: Does anyone know of a more "elegant" way to use Access and get around these limitations? I'd rather not have to tiptoe around these issues in theway described here if there is a better alternative.

RE: Orion and JNI
I think its a limitation of java, it appears you can't load a native library
from more than one class loader at a time.
To work around it, I have a class that wraps the native library, and load
the native library inside a static block as you say. I then make this class
available to a higher level class loader. Since the web-app class loaders
are children of the the orion top level class loader, and there is only one
top level class loader, the library is only loaded once, but available to
all web-apps. You can make the wrapper class available at the default
application level, by adding library tags to application.xml, or at the
system classpath level by starting orion using java -cp
orion.jar;myJNIwrapperClass.jar com.evermind.server.ApplicationServer.
Hope this helps,
Andre

Re: Orion and JNI
Hi ,
I think your library path is not properly set when you redeploy your application . I was facing the same problem .
Lets say you are accessing your native code in /private1/oracle/mycode directory . Lets say the variable name is xyz . So before starting the orion server , Explicitly set the path to export xyz=/private1/oracle/mycode and then start the orion server .
Thanks
