Not sure why the excpetion is thrown, but your solution would not work.
First, the syntax for the classpath is
<location>xxx</location>
as explained at http://incubator.apache.org/servicemix/classloaders.html
Then, if your code runs inside servicemix-ftp, you do not have to worry
about the classloader,
and if you're not inside servicemix-ftp, class loaders would be isolated (
i.e. the endpoint class loaded
by your classloader would not be the same as the class loaded by
servicemix-ftp and you will ultimately
have a ClassCastException).
I would really recommend trying to write an endpoint poller that does not
run by itself, but only
when it receives a message. You should inherit the ProviderEndpoint and
reuse the existing ftp
endpoint as much as possible (copying). Then implement the ftp polling
logic when the endpoint
processes an InOut request.

The servicemix-ftp SE has been installed and the log shows it
starting up:
INFO - ComponentMBeanImpl - Setting running state for
Component: servicemix-ftp to Started
INFO - ComponentMBeanImpl - Initializing component:
servicemix-ftp
Why would I get this exception? I tried adding a classpath to the
SU's xbean for this SE:
<property id="serverRootDirectory"
label="%servicemix30.installation.path" type="directory"
context="runtime" default="/Users/johnsos/MediaSpan/Develop/
Tools/apache-servicemix-3.1-incubating" />
<classpath>
<archive path="${serverRootDirectory}/data/smx/components/
servicemix-ftp/version_1/lib/servicemix-ftp-3.1-incubating.jar" />
</classpath>
But I still get the exception...is there something wrong with my config?
Thanks,
Scott
