I.e. tomcat 3.2.4 works, but soap doesn't? Then we
should check the patches in, they allow us to run at
least tomcat ...

We load most classes using the boot class loader,
which is the "null" you see returned above. with java
1.2 class laoding changed a bit, and now most classes
are not loaded by boot class loader, thus you see
things like "sun.misc.Launcher$AppClassLoader at 22961b "
above.

I have started to implement bits and pieces necessary
to get java 1.2 class loading to work, but that will
not be finished before 1.0.7 is out.

I'll look into the issue with SOAP (i'll try soap
2.3.1 first), and see if I have any success.

best regards,
