Re: about making .class into .jar
Ok, so if it is an executable jar, do you have a manifest? That should not give a corrupted/invalid error but it would be a reason as to why it wouldnt work. I'm not sure what would give you a corrupted/invalid error as if it could not be executed, I would assume it would take it as a non-executable jar.
Attempt to open the jar file after you change it from a zip to a jar. You can do this without changing it back to a zip (simply right click and choose Open With..., choose winRar, and uncheck "Always use the selected program to open this kind of file"). Once you have that open, have a look at the class files inside. Are they all there? Are any of their sizes 0?
If everything appears good, I am unsure where to immediately go from there.
