I have searched for this for a while now, but cant seem to figure it out. I want to extract a directory from a jar/zip file, and save it recursively to a path on the filesystem in java. Anyone know how I might do this?

Do you mean how to do this from within java code? – sinelaw Sep 25 '11 at 09:08

I have tried, and made success in extracting a file in itself, I want to extract one directory only from the jar. – Hans Sep 25 '11 at 09:51

I know that the original question was actualy doing this programmatically.
But as it wasn't clear enough I guess many users (like me) ends up here when they just want to unzip a directory out of the jar using the jar command.
jar -xvf <your>.jar <required-dir>
E.g. extract META-INF directory out of some.jar
jar -xvf some.jar META-INF
to list the content of the jar use
jar -tvf some.jar

An answer from this thread might give a good feeling how/where to start:
Simply put, it's java.util.jar you're looking for.
