Re: ClassCastException
Hi, I've figured out the problem. The server uses reflection in
org.apache.catalina.security.SecurityUtil to execute the method,
org.apache.beehive.netui.pageflow.PageFlowPageFilter.doFilter(), from
the child class org.apache.beehive.netui.pageflow.PageFlowJspFilter.
However, because PageFlowPageFilter is not a public class, trying to
access its doFilter() method causes an IllegalAccessException. Changing
that class to be public fixes the problem.
I've attached a patch for this.

Re: ClassCastException
Posted by Richard Feit <ri...@bea.com>.
Thanks for delving into this, Bryan. This is a case where reflection
and raw code behave differently (even if you look for the doFilter
method on the public class, you get the Method object from the package
protected class). Ultimately I'll probably move PageFlowPageFilter to
org.apache.beehive.netui.pageflow.internal, but for now I simply applied
your patch to it. I appreciate you following up on this.
