Hello Doug,

This is weird.  The classloader can find "X" in the static main() method
-- since you're doing Class.forName("X") there -- but can't find it
within the scope of the Y class.

I'm a bit surprised to see a URLClassLoader there.  Are you running it
as an applet or in a special environment?  Do you have a special wrapper
script around "java"?

I tried your code locally (compiled X and Y, ran Y) and it worked.  My
CLASSPATH refers to the current directory (".").  I didn't have to tweak
the bootclasspath.

~/dev/tmp/> java Y
PUT SUCCEEDED
wegscd wegscd/uid=wegscd,blahblah
~/dev/tmp/>

I'm using Sun's JDK 1.3 beta on Linux.

regards,
alex.
