Java and Rsi IDL

[Pushya]

Hello -

I have a question about integrating Java and RSI IDL(Interactive
Data Language). If I wanted to create a java GUI and call pre-written
IDL programs(methods in a program too), can that be done? I tried to
look up for this information and could not find any! Help or pointers
will be greatly appreaciated.

Thanks,
-Pushya

I think you have 3 options.

1) Execute external code from Java to run IDL (Runtime.exec()). You could
pass in data by writing it to a file from Java and reading it in in IDL.

3) If you are using IDL 6 and the OS is Windows (not sure which versions),
Linux, Solaris or Mac OSX you can try the IDL-Java bridge which allows you
to execute Java code from within IDL and transfer data between (it's not
for the feint of heart though). I have to say that my initial trials of
this on Linux were not very encouraging, and since our main platform is
sgi IRIX, which isn't supported, I didn't pursue it.

3) Use the IDL RPC interface. Use JNI to interface between your Java GUI
and an IDL RPC server.
