JNDI solution for ServiceClient.

[Berin Loritsch <bl...@apache.org>]

The following solution should fix all the EJB issues we were having.  The included file is a new
class that builds an AxisEngine in JNDI's classloader (outside of EJB's environment).  The attached
diff is the modifications required for altering ServiceClient.

Unfortunately, my cvs environment is crapping out, and I am not able to generate the diff in the
preferred format.

Also, to run the ServiceClient outside of a JNDI environment, you must use the CVS version of Excalibur.
I can send it to someone if they wish.  Another solution is to create our own simple JNDI provider--but
one already exists...
