Re: AS/400 and Java



fixed

David,
things have changed with JIT and V4R5, but some "experts" didn't
recognize this, maybe they are not reading recent documentation.
Just have a look to the mainstream of java development, which takes
place on other boxes and yoe see were the future will be. if the as400
wants to survive as java plattform, then it will go this way too.
