Huh! I think I should re-read the spec on this point to see what one should be able to assume about classloaders.
For what it's worth, I can report that I've had no trouble with jars in WEB-INF/lib under WebLogic 6.0 and 6.1 when deploying in an .ear file. So if I put struts.jar in WEB-INF/lib then it's available to the web app, and only the web app, since in 6.x at least it has a separate classloader which is a child of the EJB classloader.
