Hi,
First of all, sorry for the delay in approving this. The list is
receiving increasing amounts of spam, and real posts are becoming hard
to spot. It's better to join the list so I don't have to moderate
it...

It looks like JamVM has been built without jar/zip support within the
bootstrap class-loader. This is normally because the zlib headers or
library could not be found during configure. The clue is in the fact
that JamVM's classes.zip doesn't exist but a classes directory does
(if the boot classloader doesn't support jar/zip, the classes are not
put in a zip).
GNU Classpath is installed separately, so its classes are still in glibj.zip.
You have two choices:
1) Install zlib headers and library
2) Unpack glibj.zip, and add the containing directory to the bootclasspath, i.e.
cd /mnt/nfs/classpath/share/classpath
unzip glibj.zip
BOOTCLASSPATH=/mnt/nfs/jamvm/share/jamvm/classes:/mnt/nfs/classpath/share/classpath
Rob.
P.S. JamVM 1.4.3 is very old. Later versions of JamVM abort if zlib
can't be found, forcing the user to explicitly disable zip support (or
install the required stuff).
