.jar file cannot see what is inside

Hi,

I received this .zip file with .jar files. When I use JBuilder to see all
the classes in them I do not think that I see them all. Could they have been
stored in such a way that I do not see them all? Are they maybe stored as
classes so that I only see the java files and not the classes. Is this a
possibility? Is there any ways to actually convert the classes back into
.java files if that is the case.

TIA
Roy

A jar archive is simply a specialised form of a Zip archive.

Maybe you had better take this up with whoever
sent you the .zip file. Most '.zip files containing
.jars' come with instructions for use.

Hi,

Unfortunately I cannot reach the person that sent it to me otherwise I
would. That is the problem.

Java classloaders can find resources (classes, images,
property files, even other archives) within archives, but
they do not search for resources that are inside other
*archives* (zip or jar) that occur inside the main archive.

To see resources within archives of the main Zip, expand
the Zip file to the local filesystem, and add each jar to the
classpath of the IDE/build file.

Hi Andrew,

I tried expanding the .zip files and I get 2 .jar files, but when I try to
bring them into JBuilder it does not do anything. Can I do it with another
IDE/Build file? I am pretty new at this. Can I somehow do it through a
Command Window (DOS)?

Thanks
Roy
