Thanks for the additional info. First and foremost, I have to say
remove servlet.jar and any servlet-api or jsp-api jars from your
WEB-INF/lib folder. They are as the error indicates not allowed in your
webapp.
The part of the stack mentioning this file:
forecast_002dtest_002ddefault_jsp.java
indicates the problem is in forcast-test-default.jsp and near that spot
on the stack trace indicates it has to do with a tiles insert tag. That
tag appears to be attempting to perform an import of another jsp file.
Are there any relevant exceptions before that? This seems to imply to
me there's another error in the works in the imported jsp file.

Thanks David Smith
this trouble occured when i requested to update our run environment ( i
use r-e for short )
our old r-e is jdk1.4/tomcat4.1/hibernate2.0/
our new r-e is jdk1.6u2/tomcat5.5.23
when i start tomcat , i get following warnings , i think these
infomation may useful
validateJarFile(C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\forecastTest\WEB-INF\lib\servlet.jar) - jar not loaded. See
Servlet Spec 2.3, section 9.7.2. Offending class:
javax/servlet/Servlet.class
I guess my problem may cause by different version of jar file, my stract
trace following
ERROR [http-8080-1] (ApplicationDispatcher.java:723) - Servlet.service()
for servlet jsp threw exception
org.apache.jasper.JasperException: Attempted a bean operation on a null
