Hello,
Please see yours server.xml file and web.xml file carefully as the error arises due to this.
Please do ask other questions.

Hi Jasmine,
I am very new to tomcat and I don't know what changes I need to make
in web.xml for the "jsfks" application or server.xml in config directory.
Does the server.xml
need a new Context entry for the "jsfks" application?
Thank you so much for any suggestions you can give me.

|->bundle - contains Message.properties
|
|->jsfks - contains PersonBean.java
|
|->WebContent
|->pages - contains greeting.jsp, index.jsp and inputname.jsp
|
|->WEB-INF - contains web.xml and faces-config.xml
|->classes
| |->bundle - contains Message.properties
| |
| |->jsfks - contains PersonBean.class
|
|->lib - contains commons-beanutils.jar,commons-collections.jar,commons-digester.jar
