I am currently looking for a company who can convert large and intricate Cobol system to one of Java using automated tools. I'd appreciate it if any suggestions could be made regarding this matter.
Based on your question I have searched then web and found a website and an application to help you achieve this.
You can test the software using the provided download package (available after registration): http://www.softwaremining.com/services/COBOL_To_Java_and_CSharp_Converter.jsp
Test before you buy to see if it meets the demands. You can also check the samples to see what or how exactly is the conversion taking place.
