classpath class loading

[Jakob Praher]

hi all,

I am starting on doing some code sketches for an implementation of the
optional package versioning, which is done @ the Manifest level, where
things entries like:

Extension-Name: org.foobar
Specification-Vendor: Foobar ...
Specification-Version: 1.0
Implementation-Vendor-Id: com.xyz.foobar
Implementation-Vendor: xyz company
Implementation-Version: 1.0

for that I need some ultra fast way of handling jar files - and would
like to ask, how the classpath project does the default loading of jar
files in the classpath classloader?

- Are you using native code?
- Are you using the default java.util.jar File?

I have looked at the source, but I could find the *real* stuff in the
ClassLoader ..

any pointers are appreciated.

thanks
