官方Struts 2 + Spring 2 + JPA + AJAX的问题
我按照https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=33168官网的步骤加入包、类和配置文件， <bean id="transactionManager"
  class="org.springframework.orm.jpa.JpaTransactionManager">
  <property name="entityManagerFactory" ref="entityManagerFactory" />
  </bean>
<tx:annotation-driven transaction-manager="transactionManager" />
启动tomcat6.0的时候有问题，报错如下:
