Bruce,

Thanks a lot for your input. I totally agree with you and I have the same
perspective as yours. So, you basically went to each .rpgle and .dspf source
code and started coding them into .jsp's and .java classes, right? Some of
the .rpgle applications may be made into swing component loaded front
facade's, I surmise. I think that is the best way to go rather than pushing
the .rpgle code through a 'black box' and ending up with so called Java code
which will take a steep learning curve to understand.

I also agree with the fact that Java has grown by leaps and bounds and has
awesome capabilities right now as compared to a few years ago.

Oh, BTW J in AJAX is Javascript...:-0). It is a wonderful technology. Can
you believe that MS floated this a few years ago?

cheers,

Jake.

We had the same question 5 years ago. After looked at all the options we
decided to code it out. Now we have hundreds of dds screens, rpg/cl in
Java. Things are greatly simplified now since Java is much better and we
have completely control of the code.

The danger with Java is that it is very deep and rich as opposed to RPG
witch is primitive and procedural.  One almost has to master some degree
of OOP programming to make things right. Line to line translation will
hardly work.

The good news is that Java has advanced greatly in the last 5 years. JDK
1.3.,4,.5 and soon 1.6 offer amazing capabilities. Also numerous common
tasks are programmed for free use. For system infrastructure there is
Spring framework; for database programming there are Hibernate, iBatis,
Spring etc; for any other tasks look first at apache.org; for web
application there are JSF, AJAX (does JA in ajax refer to Java?).

Jon and other Pro's,
So, here is a honest question. Is it a good idea to go translated Java

from

RPG, which could be a hybrid of RPG and Java? Or is it good to go to

'RPG

converted to native Java' which could be understood even by our jr
programmers. I would really appreciate any kind of input on this

subject.

cheers,

Jake.

How closely does VARPG follow RPGLE?

I think it is currently at a V5R3 level - but my copy has been screwed

up

by
registry problems and I haven't had time to fix it - so I can't check

it

out.
