Kaffe having trouble with gnujsp.jar

Apologies if this arrives twice - this is my first posting to the list
and the subscribe message (which gave the address as
kaffe at transvirtual.com) contradicts the "to" fields of every message I'm
receiving from the list (which say kaffe at rufus.w3.org). Since I didn't
receive a copy of this posting back from the list, I'm assuming that
kaffe at transvirtual.com is wrong.

I am finding that kaffe from the latest CVS (and also 1.0.5) is unable
to load or read the "gnujsp.jar" file that comes with gnujsp 1.0.0. When
I try to use the classes, I get a ClassNotFoundException wrapped in an
ExceptionInInitializerError -

java.lang.ExceptionInInitializerError: [exception was
java.lang.NoClassDefFoundError: org/gjt/jsp/JspFactoryImpl]
	at kaffe.lang.SystemClassLoader.findClass(SystemClassLoader.java:93)

So I decided to take a look at the jar file with jar...

	at kaffe.tools.jar.Jar.main(Jar.java:39)

(actually, that stack trace came from 1.0.5; I get a different error
from the latest CVS but it seems to be some kind of a configuration
error...

sballard at rainbow:~/kaffe$ jar tvf /usr/share/java/gnujsp.jar

	at kaffe.tools.jar.Jar.main(Jar.java:39)

... So everything I'm doing with jar is the 1.0.5 jar tool)

I tried un-jarring the jar with sun's jar and re-jarring with kaffe:

In other words, jar could not even read the file that *it* created!

Now, I'd love to debug this, but I know nothing about zip or jar files.
Does anyone have any clues about it? I can gladly send you a copy of my
gnujsp.jar file (and of course you can get it from the gnujsp website or
in the debian gnujsp package, which is where I got it).

Also, does anyone have any idea about the error in jar from the latest
CVS - the UnsatisfiedLinkError that I quoted above? If I could get the
latest CVS to work, at least I would be able to get gdb onto this...

Thanks in advance for any help,
Stuart.

PS I'm sure I didn't quite re-jar correctly, but I got the same result
whether I included the META-INF directory as a regular directory (as
above) or whether I excluded it and passed -m META-INF/MANIFEST.MF
explicitly.
