That's on the workstation, Phil. On the AS/400, the -D is all that is needed. Try it sometime. Just run the following from QShell: java -Djava.version=1.3 version java -Djava.version=1.4 version See what happens. My understanding is that all versions of the OS/400 java executable will check the java.version setting prior to doing anything else.
