java - JNDI 需要 JDK 吗？

Question

我尝试从 SUSE Linux Enterprise Server 为 Tomcat6 配置 Oracle 数据源。我将数据源添加到 context.xml 文件:

   <Resource 
   name="jdbc/UCPPool"
   auth="Container"
   factory="oracle.ucp.jdbc.PoolDataSourceImpl"
   type="oracle.ucp.jdbc.PoolDataSource"
   description="Pas testing UCP Pool in Tomcat"
   connectionFactoryClassName="oracle.jdbc.pool.OracleDataSource"
   minPoolSize="2"
   maxPoolSize="5"
   inactiveConnectionTimeout="20"
   user="scott"
   password="tiger"
   url="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)
        (HOST=beast.au.oracle.com)(PORT=1523))(CONNECT_DATA=
        (SERVICE_NAME=linux11gr2)))"
   connectionPoolName="UCPPool"
   validateConnectionOnBorrow="true"
   sqlForValidateConnection="select 1 from DUAL" />

在我的应用程序中的 persistence.xml 添加非 jta-data-source 属性。但是每次我想启动应用程序时，tomcat 都会抛出这个异常:

   Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [java:comp/env/jdbc/nameDB]

我在 OpenSuse 上尝试了相同的配置，并且可以正常工作。我发现的唯一区别是 SLSE 安装了来自 IBM 的 JAVA SE，而 openSUSE 默认使用 OpenJDK java。

那么 JNDI 需要 JDK 还是 IBM java implmenetation 中的一些错误？

要回答标题中的问题，不，JNDI 是 JRE 的一部分。不需要 JDK。
