making a jar file with multiple classes and jars

[munchy1988]

I want to make a jar file that must also contain 2 jar files. is it possible to do this? and how would i go about doing it?

also, i would like to include some picture files and somehow reference them in the jar file somehow. could someone tell me how i could do this?

its been almost a year since i programmed in java, and it sucks relearning it all.
