Re: RPG to Java Conversion Tool.

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?). 

Regards.

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.
