I am sorry, but if I understand correctly, this is an issue with the console
not the connector. The Tomcat HTTPS connector runs fine as it serves SSL
without any issue. I don't think we will remove this connector as it will
remove SSL capabilities with Tomcat and also remove its J2EE certification.

Subject: Re: Help ... proxy problem with tomcat web connectors
I guess TomcatWebSSLConnector is having problems. I have hit upon
this error while trying to list the Tomcat Web Connectors. See the thread
http://mail-archives.apache.org/mod_mbox/geronimo-dev/200510.mbox/%3cBAY103-
[EMAIL PROTECTED]
I suggest to remove the Tomcat HTTPS Connector from the Tomcat
configuration for now and build rest of the code.

Well I've figured out a way around this problem but I can't
for the life
of me explain why it eliminates the problem. This may even
be a problem
in CGLib but this work around at least avoids it for now.
It seems to be a problem with the selection of the class
loader.
Here's the class/interface configuration with the problem:
- We currently have defined 2 interfaces that both extend
from a common
interface (say A and B that extend from Z). An
implementation
class(IA) implements one of the interfaces(A). Another
implementation
class(IB) extends IA and implements B.
- When we attempt to create a proxy for the GBean object, we
get the
NoClassDefFoundError exception in the original post while
attempting to
load the interface A.
I took a look at Jetty(which isn't hitting this problem) and
the only
difference appeared to be another interface(C) that is in
the same
package as B between the interface B and the class IB (which
is really
strange because A was the interface pointed to by the error
... not B).
After rebuilding I no longer get the NoClassDefFoundError
exception.
Anybody have an explanation or theory on this?
Does somebody with more experience on CGLib think it's
likely a problem
there?

No, this interface reduction is doing it's job to ensure
that we have
the least number of interfaces while still representing all
of the
object's capabilities.
