can't start struts1.1 RC1 example in Websphere 4.0.1 AE

[david chan]

Hi,
I have websphere 4.0.1 Advance Server Edition running
on my win2000 PC.
I successfully deploy and run Struts 1.0.2 example to
Websphere 4.0.1 AE, but failed to run Struts 1.1 RC 1
example, it deploys fine but when I try to start the
example application within admin console, it failed
with this error mesg. Any idea?
== error mesg:
