Unfortunately, you're not the only one seeing these problems. I really
thought I'd tested the struts-example app with four different containers
(Tomcat 3.3a, Tomcat 4.0.3, Resin 1.2.10, Resin 2.0.5) before I released the
beta, but it seems I must not have tested under Tomcat 3.3a. ;-( The other
three work just fine.
Here's what I know so far:
1) The problem is related to class loaders, and possibly to the
LogFactory.findClassLoader() method. The fact that LogFactory.getLog() is
called at (ActionServlet) class initialisation time may also be significant.
2) It is related to the <load-on-startup> element. If the web app is not
loaded on startup, this error does not occur. (Others do, of course, but we
get past this problem.)
3) The problem can be worked around by copying commons-logging.jar to:
%TOMCAT_HOME%\lib\common
Unfortunately, I'm by no means a class loader expert, so I'm not sure where
to go from here. Hopefully someone who has more class loader knowledge than
I do can chip in now...
