onContext-Local.xml]

二）Caused by: java.lang.NoClassDefFoundError: LUpdated;
很奇怪的问题。项目中使用git stash后出来的问题。
解决方法主要是clean项目：
1）server 右键 clean；
2）项目上refresh
3）删除tomcat，从workspace和project
4）删除eclipse中项目的临时文件夹在org.eclipse.wst.server.core

三）配置tomcat 和jboss
1)先去掉项目，单独运行tomcat
2）错误一般在比较靠近下方的位置提示
3）删除jboss-as-7.1.1.Final\standalone\deployments目录下的项目
补充第2）点：
配置代码如下：

<bean id="defaultEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitManager" ref="defaultPersistenceUnitManager" />
<property name="persistenceUnitName" value="default" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect"></property>
</bean>
</property>
<property name="jpaDialect">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"></bean>
    </property>
<property name="jpaProperties">
<props>
<prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>
<prop key="hibernate.archive.autodetection">class</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
