Nope, I've discovered the same to be true, but I would like it if classes
reloaded....

Please
respond to
soap-user
There is no way to refresh compiled classes loaded via the TomCat .\classes
folder, that I'm aware of, other than to restart TomCat itself.
I think it would be possible if the classes were loaded via the
.\webapps\soap\WEB-INF\classes, but that's not how Apache-SOAP seems to
work...
Please someone tell me I'm wrong <g>
Note: I'm using TOMCAT v3.2.1, later versions may work differently.
