------ Solution ----------------------- ---------------------
tomcat startup when there is no error ? Seemingly not the easiest , is still dependent on hibernate, struts framework like
------ Solution ------------------------ --------------------
Caused by: java.lang.ClassNotFoundException: org.hibernate.HibernateException

java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

little package
------ Solution ---------------------------------- ----------
first solve the foremost mistake, because subsequent error may caused by the front :

seems to be missing the Hibernate package
------ Solution ----------------------------- ---------------
first solve these two problems, import jar package, or comment related things.
java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

Caused by: java.lang.NoClassDefFoundError: org / hibernate / HibernateException
------ Solution ----------------- ---------------------------
first you have to make sure you join hibernate package is placed where ? Yes add external jars or directly on the web-info lib directory , it should be placed directly on the web-info lib directory .
------ For reference only -------------------------------------- -
problem is that I find step by step to a source of errors , and deliberately let this dynamic web project is just a single jsp file, print a hello world, do not need to hibernate Yeah, why do not hibernate error will be reported it ?
------ For reference only -------------------------------------- -
and my java build path in add external jars joined hibernat4.1.8 the required folder in the package , or not.
------ For reference only -------------------------------------- -
and add external jars added a hibernat4.1.8 the required folder in the package , there is still java.LANG. noclassfounderror: org / hibernate / hibernateexception

my similar mistakes
sqlserver2000 in
String driverName = "com.microsoft. jdbc.sqlserver . SQLServerDriver ";
String dbURL = "jdbc: microsoft: sqlserver :/ / localhost: 1433; DatabaseName = sa "
distinction server2005 to server2012
String driverName = "com.microsoft. sqlserver.jdbc . SQLServerDriver ";
String dbURL = "jdbc: sqlserver :/ / localhost: 1433; DatabaseName = sa "
otherwise will be reported missing drivers or tomcat log file will say connection: refused
