I did try to unzip the .jar file; now I see in the documentation that I have
to restart the server for it to pick up changes to servlet classes not
located in the "servlets" directory. This seems to apply also to
subdirectories off the servlets directory. This is a problem, though for now
I can simply .jar up my supporting classes and change the servlet classes
themselves so they are not in a package's subdirectory. Any other
suggestions I should consider? Thanks.

Thanks,

Well, that's strange, the ClassLoader should be the system ClassLoader
because the servlet class is in the CLASSPATH. Did you try to unzip
the jar file?

What

in
