spring＋struts＋hibernate升级hibernate2到3，出现找不到JD...

原来一个简单的测试例子，用spring 1.2 ＋struts1.1＋hibernate 2编写

最近升级hibernate2到hibernate3，升级步骤为：

 make use of Hibernate metadata as well as Spring. Here's my list of
all the changes I had to make to run my application with HB3 on
WebLogic. This may repeat some of this information above and is not
meant to be exhaustive.

1.  global replace net.sf.hibernate to org.hibernate (be sure to include
the XML configuration files as well);
2.  global replace org.springframework.orm.hibernate to
org.springframework.orm.hibernate3 (be sure to include the XML
configuration files as well);
3.  global replace net.sf.hibernate.expression.Expression to
org.hibernate.criterion.Expression
4.  global replace net.sf.hibernate.expression.Order to
org.hibernate.criterion.Order
5.  convert method call getHibernateTemplate.getNamedQuery(Session sess,
String query); to session.getNamedQuery(String query);
6.  convert method call getHibernateTemplate();.createCriteria(session,
getReferenceClass();); to session.createCriteria(getReferenceClass(););
7.  Add new EntityMode.POJO parameter as follows to:
ClassMetadata.getPropertyValue(dest,
SkipFields.TCN.toString();.substring(1);, EntityMode.POJO);
8.  Add new EntityMode.POJO parameter as follows to:
classMetadata.getMappedClass(EntityMode.POJO);
9.  global replace HibernateProxyHelper.getClass(object); to
HibernateProxyHelper.getClassWithoutInitializingProxy(object);;
10.  Convert method call: propertyTypes.isPersistentCollectionType();); to
propertyTypes.isCollectionType(););
11.  Update the DTD as follows:
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
12.  Replace in the HBM files any instance of “<generator class=”vm” />
to of “<generator class=”native” />
13.  Add lazy=”false” to any class or association if you don’t use to use
lazy initialization. However, this is strongly discouraged and thus why
the default is now set to true.
14.  Caching is now enabled by default using the EHCache. If you want to
disable this, you must do this from the hibernate.cfg.xml. Again, this
is strongly discouraged.
15.  Remove all the previous versions of the .jars associated with
Hibernate and replace them with the new versions. 
 

升级完成以后编译通过。

可是在启动tomcat时候出现错误

具体原因我不知道？那个大人能解释一下。为什么上面的在 hibernate2没有问题？
