Re: [JBoss-user] HOWTO: Call an EJB from an Oracle Java Stored Procedure
Sure, I'd be willing to help with this, since I'm benefiting from it.
Two additional thoughts came to mind after I sent my last message:
(1) Your steps said to load the EJB into Oracle. Technically, you just
want to load the home and remote interfaces, and not the bean class.
With versions 2.x of JBoss, having the bean class in the client
classpath would make hot deploy appear not to work. Don't know if that
is still true in 3.x.
(2) The Oracle JVM has IIOP support built-in. I'm wondering if we
switch to IIOP instead of defaulting to JRMP, if we can eliminate having
to load a bunch of protocol classes into Oracle. As an aside, I
happened to notice reading through some Oracle JVM documentation that
they specifically say not to do RMI inside Java stored procedures. It
said that RMI starts up its own threads, and starting threads in stored
procs is discouraged since it makes Oracle's session management flaky.
Oh, well, we'll have to ignore this rule since without RMI we'd be done
before we started.

Agreed ?

udump. I really
should delete all Java permissions and start from

(1) Where did you find the OracleLoadJava task for

jbossall-client.jar
(figuring it was redundant). Again, I'll probably
start from scratch to
see if I can pare down what is needed. After
recompiling the INVALID
classes, I'm still showing 488 classes that are
marked INVALID. Many of
them look pretty fundamental (i.e., necessary), so
I'm wondering once we
move beyond a trivial example if this will continue
to work.
(3) Your steps say to recompile these INVALID

following accomplishes the same thing, and gets done
much faster:
- First, load all the jar files without resolving.
Don't know how to do
this in Ant, but from a command line you can do it
like this:
call loadjava -user GUYR/[EMAIL PROTECTED]
concurrent.jar
- Then make a second pass through all the jars, this
time invoking the
resolver. This looks like this:
call loadjava -resolve -resolver "((* GUYR)
(* PUBLIC))" -user
GUYR/[EMAIL PROTECTED] concurrent.jar

I went back to reproducs this, and the process was
this using
Windows XP Professional
JBoss jboss-3.2.0_tomcat-4.1.24
Oracle Enterprise Version 9.2.0.1.0
1. LoadJava the entire JBoss Client Jar collection

Run the script that is generated.
3. Grant the following rights to SCOTT:

There may be some extra ones in there. I was also

I found Oracle to be a little unstable when testing
this, but once it is loaded and all the classes are
fully compiled in Oracle, it is pretty snappy.
