Re: Calling Java from RPG - CLASSPATH Problem?

["Shannon O'Donnell" <sodonnell@xxxxxxxxxxxxxxx>]

Thanks to all!  I changed the Java to return a Byte array instead of a
String and it all worked great.

I have to say that I learn something new every time I delve into Java.  And
I also feel, again, that IBM didn't do AS/400 programmers any favor by
hiding the complexity of the nitty gritty of programming behind so much in
RPG.  For example,  a  CHAIN in RPG is easy.   Setting up an input stream,
reading bytes of data from a file, etc...piece by piece, the way you have to
do it in other languages such as Java, is so much more complex by
comparison. AS/400 programmers have not had to deal with that complexity,
they simply execute a CHAIN.  And because of that, when they want to move
to/try a new language, there's a tremendous learning curve.  It would have
been easier to learn it all from the beginning.

Ah well....if it was easy, any one could do it. :-)

Thanks again!

Shannon O'Donnell
