JNDI需要JDK嗎？

我嘗試從SUSE Linux Enterprise Server爲Tomcat6配置Oracle日期來源。我想補充的數據源context.xml文件：JNDI需要JDK嗎？

<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persistence.xml應用程序中添加非JTA-DataSource屬性。但是，當我想啓動應用程序每次下，Tomcat拋出此異常：

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

我試圖在openSUSE相同的配置，有它的工作原理。我發現唯一的區別是SLSE安裝了IBM的JAVA SE，openSUSE使用OpenJDK java作爲默認設置。

那麼JNDI需要JDK還是它是IBM java implmenetation中的一些錯誤？

在您的資源定義中，名稱是'jdbc/UCPPool'，但是當您查找它時，您的名字是'jdbc/nameDB'。這不正確嗎？ – Jesper

我只是忘了改變，當我從堆棧跟蹤複製。但eache時間我使用相同的名稱 – ostry

要回答標題中的問題，不，JNDI是JRE的一部分。不需要JDK。

謝謝你的迴應。你有什麼想法，爲什麼這不起作用？ – ostry
