How can I put my app with all libs in a singe-jar?

Thread view:

I have written an hybrid applet (applet + application) which uses some
libs.

Is there a possibility to put the application (only classes and
properties) and the libs (jar-files) into a singe-jar without to
extract all data from the libs to the application?

kind regards

Markus

Seems like a lot of work, and not very flexible. But I don't see why
you can't do it.

The Problem is that jars will not be found if they are inside an other
jar.

To be honest, I never thought that was a problem.

ProGuard seems to be a solution but is there no possibility to use the
classes from the jars inside the jar?

not without a custom class loader.

On OSGi they are, we have the Bundle-Classpath that can point to JARs
inside JARs as well as directories.

if you put the classes into one big jar and don't nest, i.e. put the
oher jars in directly, all should be ok.

Take a look at ProGuard. It unpacks all your libraries, identifies the
classes actually used (optional), and packs them all up into a single jar.

Be careful about licensing. Some of the licenses in those jars might
prohibit the distribution of the classes outside of the original jars.
