Re: Calling Java Method from within RPG

[MWalter@xxxxxxxxxxxxxxx]

Paul,

Thanks, yea I got that to work. But the profile Token I'm converting is
coming back as invalid. I think it has something to do with the differences
between the ASCII and EBCDIC character sets.

Thanks,

Mark

Mark,

Your decode procedure prototype should take a string class as a parameter
instead of the ...base64 class.  It's trying to find a decode function that
accepts such a class and can't find it.
