running struts-example problem

[tina zhang <zz...@gmail.com>]

Hi All,

I installed struts 1.2.9 into my computer, then copied struts webapps
WAR files into tomcat_home/webapps folder, and they were deployed by
the server, but when I run struts-blank and struts-mailreader, I got
the following exception:

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception
