If the classpath is an environment variable, you may
need to reinitialize the environment, but on NT this
has usually just required closing a window (and
restarting the server, of course.)

If you're looking to load foo.bar.Yuk as a class, then you add
some directory which contains foo as a subdirectory (so that
foo/bar/Yuk.class is included from that point).

(1)You may be having a version trouble...bsfengines.jar was
separate from bsf.jar in older versions, but according to
  http://mailman.real-time.com/pipermail/cocoon-devel/2000-November/003332.html
the xalan2 bsf.jar, which seems to be the same as the soap
distribution bsf.jar, has incorporated bsfengines.jar; I
don't have bsfengines.jar in my setup, which works fine.
It might be a good idea for you to get rid of your old
xerces/xalan stuff, including anything distributed with
Tomcat (move things into temporary directories) and just
put in the current xerces.

(2) If the file "c:\apache_soap\rhino\rhino\js.jar"
does not exist, I think you'd get the error message you're
getting (try removing it and see if anything changes; try
putting it into your java_home/jre/lib/ext directory and
see if anything changes) 
(3) You might want to download bsf from
   http://oss.software.ibm.com/developerworks/projects/bsf
and js from http://www.mozilla.org/rhino/download.html
and see what you can get to work in isolation; each of
course comes with javadoc and examples, and if your problem
is that bsf can't find js within soap then it might be best 
to first make sure you can run js, then make sure bsf can
find it outside of soap.
(4) or you might just want to check within a jsp, say insert

into cp.jsp -- it won't compile unless the class is found,
of course.
