Packaging a files to JAR?

[Christer Nordvik]

How do I package all my files to a single jar file? I have libraries that
are jar files themselves.

My file:
prog.class

Includes:
demo.jar

I have tried: "jar cvm myNewJarFile.jar prog.class demo.jar" , but that
didn't work when I tried to run my program.

I don't know why you need to do that, but if you want to then you do this:

1. Take all the files out of demo.jar and put them into a directory
somewhere.

2. Put prog.class and all files in that new directory into the new jar
file.

Christer,

You almost had it right. You want to use "jar cf myNewJarFile.jar prog.class
demo.jar". The "f" flag is so you can specify the jar filename.

I found that the jar file within the jar file could not be used in the classpath
though. What you might want to do is to extract the jar archive with "jar
xf jarfile.jar" and put the class files into your jarfile.

I hope that this helps you out.
