Process Description:

1. A standalone Java client is executing on the OS390 USS (version info is included below)
2. It is trying to make an RMI call to a Session EJB residing on Oracle 9IAS (Release 2 - 9.0.3) residing on HP Unix (environment info is included below).
3. Necessary jar files to make the Client code make the RMI call are included in the classpath of the client. These support files have been downloaded from Oracle website. Oracle claims that the support software is certified for Linux 390 or IBM S/390 based linux, none of which is our case.

Subject: OT - MVS / Java / Oracle 9iAS

I am a Java-idiot.
I am hoping some of the brilliant people on this list can help me
A developer came to me with a problem they are having.

He is setting up a JVM to run under USS (Unix System Services) on OS/390 v2.10
He has java code that uses (RMI)IIOP to talk to a EJB on 9iAS running on HPUX
This is failing with UFT-8 error.

The mainframe code page is IBM-1047. JDK is IBM 1.3.1

HP code page is ISO88859-1 using JDK 1.4.1

This did not work, so he copied the JVM from Oracle download to replace the one in USS
(6 libraries / files or something like that) and it still did not work.

If any one has ANY ideas of what I can do to help him,
where to look, etc

TIA - Babette
