Answer 1

the class com/table/values/SubjectScoreWithSubjectName.class is not accesible by your application.
Try including it in WEB-INF\lib folder, or including it in your server's CLASSPATH
UPDATE
See http://www.servletworld.com/servlet-tutorials/web-application-directory-structure.html for the basic structure of a Java EE app.
Generally, your libraries (jars) should be in web-inf/lib and your classes in web-inf/classes folder.
If com/table/values/SubjectScoreWithSubjectName is a separate class it should go into the classes folder, but if it is in a library that you are importing in your app it should go to the lib folder.
