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!

Welcome to JavaRanch, Alexander!
I'm moving this to the IDEs and Other Tools forum...

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.
