How to decompile a whole Jar file? [closed]

Question

Does anyone know of a free decompiler that can decompile an entire Jar file instead of a single class? I have a problem with sub classes like name$1.class name$2.class name.class

Answer 1

If you happen to have both a bash shell and jad:

JAR=(your jar file name)
unzip -d $JAR.tmp $JAR
pushd $JAR.tmp
for f in `find . -name '*.class'`; do
    jad -d $(dirname $f) -s java -lnc $f
done
popd

I might be a tiny, tiny bit off with that, but it should work more or less as advertised. You should end up with $JAR.tmp containing your decompiled files.

Answer 2

Something like:

jar -xf foo.jar && find . -iname "*.class" | xargs /opt/local/bin/jad -r

maybe?

Note: This solution only works for Mac and *nix users.

I also tried to find Jad with no luck. My quick solution was to download MacJad that contains jad. Once you downloaded it you can find jad in [where-you-downloaded-macjad]/MacJAD/Contents/Resources/jad.
