Question

I’m still pretty new to java and I’m VERY new to exporting .jar files. I’ve got a little game that I want to send to some friends and I was told in another question that I should export it to an executable jar file. Well I finally got that working on my computer but when I send it to other people it doesn’t work because they don’t have the library.

I’m importing the objectdraw library and without that my program won’t run at all!

So basically I need to find a way to export the object draw library as part of my .jar file so that they can use it too. Do I simply include it in the included files part of the jar command?
ex: jar cmf MANIFEST.mf Archery.jar * /System/Library/Java/Extensions/objectdraw.jar

or what? I’m working out of the command line right now.

Turns out the best way I’ve found to do this is to unpack the library and then put all the resulting files in with your final archive. This way it actually works on other computers.

jar xf library_wanted.jar; jar cvmf MANIFEST.mf end_result.jar *.class library_wanted/
