the key lines to look at more closely at these:
java.lang.ClassCastException
org.apache.jsp.errorpage_jsp._jspService(errorpage_jsp.java:103)
...
org.apache.jsp.preview_jsp._jspService(preview_jsp.java:135)
(esp the latter), and:
"note The full stack trace of the root cause is available in the Apache
Tomcat/5.0.27 logs"
I would take a look at the logs for more info then look at the lines in the
_jsp.java files mentioned in the stacktrace above. These "_jsp.java" files
are the java source files defining the servlets that TC automatically
converts your JSPs into. You should be able to recognise from there where
the error is in your JSP source. You will find the files in this folder:
%catalina_home%/work/[engine-name]/[host-name]/[webapp-name]/org/apache/jsp/
where [engine-name] and [host-name] are usually "catalina" and "localhost"
unless you have changed them in %catalina_home%/conf/server.xml
