Re: EJB versus RPG/COBOL

["Colin Williams" <colin.williams@xxxxxxxxxxxx>]

Joe,

agree with everything you've said.

I have found that Java is good for non database / utility type stuff, 'cos
so much has been built already.

eg FTP, email, IFS object handling is very easy to do in Java, and
conversely, fairly painful and messy to do in RPG.

cheers
