I am attempting to create a jar file, however i am having a difficult time solving it as i personally do not have access to a machine that can not run the jar file. It works fine on my computer, school computer and a friends computer. However, none of my other friends i send it to can get it to work unless they personally compile or make a jar file.
The problem i am told they are getting is the main class issue where it cannot be found. I have tried a handful of different methods i was able to find online to fix this but none have seemed to work, and i am also getting tired of sending and resending jar files to see if they work. The final issue i was not able to test is that jar files can only be run in the environment they were created in. I have java 7 but it seems the rest of the world has java 6. will i need to download java 6 and compile using that JRE and pray that it doesnt update tomorrow morning?
