RE: compiling on PC

["Clapham, Paul" <pclapham@xxxxxxxxxxxxx>]

It ain't necessarily so.  You can take a class compiled by a 1.3 compiler
and run it in a 1.2, or even a 1.1, JVM.  That's one of the unanticipated
side-effects of "write once, run anywhere".  However, if you do that you may
encounter "UnknownMethod" (I think) errors, if you were too enthusiastic
about adopting new features.  But it looks to me as if you could avoid that
by using the "-target" option of Sun's javac command, for example "javac
-target 1.2 AnyClass.java".

Most people find it easier to do the compiles on the PC, not OS/400.

You have a special problem, though.  Your OS/400 is at 1.2 and your PC at
1.3

Can you get some sort of optional install of 1.2 on your PC?

Can you upgrade your OS/400 to 1.3?

One way or the other, you need to get your development IDE "behind"
OS/400, not ahead of it.
