Subject Re: Tomcat Servlet API and init methods
Date Fri, 28 Jul 2000 19:17:13 GMT

AFAIU this is not a good idea for the reason that classloaders should not cross
context boundaries. The first practical example which comes to mind is the fact
that different context may use different versions of the same class, so they
have to be completely isolated.
