I wouldn't remove it from the Tomcat config either. Removing it is purely a
treatement to the problem, not a solution. I think we should just attack the
problem and figure out what its getting this error to begin with.
This seems to be a classloader issue of some form. Has anyone who worked
with the console taken this issue (I am assuming there is a JIRA attached to
it)?

Subject: Re: Help ... proxy problem with tomcat web connectors
Jeff,
I do not mean to suggest to knock-off Tomcat HTTPS Connectors
altogether. Ofcourse, we CANNOT remove Tomcat HTTPS Connectors. I only
suggested to remove the Tomcat HTTPS Connectors from the configuration while
getting any additional functionality up and running. Just to give an
example, I was updating the Web Servers portlet to list Tomcat Web
Connectors and I was getting blocked by this exception before I could test
any of the code updates to the portlet. I realized that I could test my
portlet if I removed the Tomcat HTTPS Connector from the configuration
temporarily. My suggestion was in similar lines.

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

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

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
