Ok, know that my project is almost finished (thanks to danpost) I want to export it to jar (already done) but then conver it to exe. (already done) Now, I need to conver it to a wrapped up exe. I mean, to an exe that does not need JRE installed in order to run the program. In order to do so, I downloaded some tools. The Jwrapper seems like the most simple one. But it is asking for the classpath and I don't know how to get it. I got the main class from another tool (Jar2Exe) which shows that info when I upload the. jar. Look at it: Is there any way i can get it?
