error on page: enter link description here

the page made jsp

and have no idea how fix this...

this dao-file:

import java.util.list; import javax.persistence.entitymanager; import javax.persistence.entitymanagerfactory; import javax.persistence.entitytransaction; import javax.persistence.persistence; import javax.persistence.persistencecontext; import model.customer; import model.milestone; import model.project; import model.task; import model.user;  public class jpadao implements dao {     private static jpadao dao;      public static jpadao getinstance() {         if (dao == null)             dao = new jpadao();         return dao;     }      private entitymanagerfactory emf = persistence.createentitymanagerfactory("fishsticks");      @persistencecontext(name="fishsticksem")     private entitymanager em = emf.createentitymanager();     private entitytransaction tx = em.gettransaction();      private jpadao() {         // singleton     } } 

did follow advise tomcat documentation?

before proceed, don't forget copy jdbc driver's jar $catalina_home/lib

this tomcat 6.0 , 7.0.

for tomcat 5.5: $catalina_home/common/lib
