I'v read the thread about loading the JDBC classes on a PA RISC system, and I have the same problem on HP/UX 11. Starting the Orion server in the Orion root path does not help, copying it into $JRE/lib does the job, but it seems to be an UGLY hack. Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.00-release-010607-19:35-PA_RISC2.0 PA2.0, mixed mode) Orion 1.5.2 Any reaction would be very helpful.
