I am currently working on a java program that has to be converted to a DLL or exe file so that another program written in any language could access to the java program. The java program was written in IBM VisualAge for java running on Windows 2000 platform. I have tried using Executor program someone has posted, but I always get an error saying 'Main-class" attribute is needed" I've added "Main-class: nameofmymainclass"to my manifest file, but I still get the same message. Does anyone know how VisualAge converts a class file into exe file or how to modify the manifest file correctly. Thanks
