Using Project Builder I can create a double-clickable MacOSX application from my jar files. But I don't know how to create a Windows application. I know InstallAnywhere would do what I want but for now it is beyond my budget. Where should I go?
The JRE for Windows also includes this functionality whereby you can double-click on a JAR file to execute the application contained within. All you need to do is set the Main-Class attribute of the manifest appropriately. Have you tried running the same JAR file on Windows? If so, what happens?
