spring配置 jboss 的jndi数据源出错

oracle-ds.xml配置如下： 
Java代码 
<?xml version="1.0" encoding="UTF-8"?>   
  
<datasources>   
  
  <local-tx-datasource>   
    <jndi-name>DataSource</jndi-name>   
    <connection-url>jdbc:oracle:thin:@192.168.1.111:1521:ora11</connection-url>

 <idle-timeout-minutes>2</idle-timeout-minutes>   
  </local-tx-datasource>   
  
</datasources>   
  
  
applicationContext.xml配置如下：   
<?xml version="1.0" encoding="UTF-8"?>

  </local-tx-datasource></datasources>
applicationContext.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       <property name="jndiName">
       <value>DataSource</value> 
      </property>
    </bean> </beans>启动jboss时总提示 
18:01:41,564 INFO  [STDOUT] 18:01:41,562 ERROR [ContextLoader] Context initialization failed 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: DataSource not bound 
我检查了WEB-INF下lib包，没其他jboss的jar文件。因为我用的是jdk1.6 + oracle11 ，odbc6.jar也分别拷贝到jboss\server\default\lib下和WEb-inf\lib下拉。 
我在google上查的帖子，别人将 <use-java-context>false</use-java-context>设置一下就不会报这个not bound错误了，为什么我还一直出错呢 
问题补充：
java:/DataSource 我原来试过了不行。打印的信息中显示 14:53:06,100 INFO  [WrapperDataSourceService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=DataSource' to JNDI name 'DataSource' datasource已经绑定成功了。但applicationContext。xml中第一个bean无论写什么内容。都会报错google上面查询，别人是多了一个 
jboss的jar包。删掉就ok了。但我这个没有多余的什么jar包啊
