Could somebody help me with opinions and experiences on automatic tools, that provide Cobol to Java translations? I already did a search on Google and have seen numerous ads and numerous products. I have found, that only few of them provide evaluational versions, so I'm eager to hear from anybody, who have any experience with such a tool. I will gladly consider all opinions!
Alexander, although there are products out there, as you have stated, but why do you want to do this. I would assume that the structural programming nature of COBOL would make it almost impossible to convert a COBOL app into a good well designed Object Oriented Java application. Personally I think you will be better off writing the Java from scratch and design the application appropriately. My Opinion of course. Mark p.s I came from a company that had COBOL applications and we would never consider using some kind of conversion tool
There was a guy at the comp.lang.cobol newsgroup who did write such a converter (and was advertising it). I had a look at the generated code; and while I admire the guy's efforts -- I thought the converted code would be a maintenance nightmare.
Any program turning structural code into OO code will yield a maintenance nightmare (in fact you can probably extend that to saying (almost) any code generator will cause a maintenance nightmare). You're far better off starting from scratch, maybe tackle the original application in small pieces at a time so you can leverage the power of it while the new system isn't complete yet.
