这个问题产生的原因是找到了，其实和这个报错感觉相差很远。原因是在web工程中，我不小心拷贝进去了一个 ejb的jar包，ejb工程已经单独启动，其中关联jboss配置了jndi的数据源链接，启动web时再次加载ejb的jar包引入数据源，就报了上面的错。

总结来说，是个人不够细致导致的问题，但这报错也太特么搞人了，花了一天时间。

下面还是说点有用的吧，这个报错看起来是设置数据库链接方言导致的问题，我本地的配置如下：

<properties>
	<property name="hibernate.hbm2ddl.auto" value="none"/>
	<property name="hibernate.jdbc.fetch_size" value="10"/>
	<property name="hibernate.jdbc.batch_size" value="20"/>
	<property name="hibernate.show_sql" value="false"/>
	<property name="hibernate.format_sql" value="true"/>
	<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
</properties>

org.hibernate.dialect.Oracle10gDialec 来自 hibernate-core-3.3.1.GA.jar包，本地组合jar包有以下几个：

        hibernate-annotations-3.4.0.GA.jar

        hibernate-commons-annotations-3.1.0.GA.jar

        hibernate-core-3.3.1.GA.jar

        hibernate-jmx-3.3.1.GA.jar

正常引用这几个包可以访问数据库。
