我尝试从 SUSE Linux Enterprise Server 为 Tomcat6 配置 Oracle 日期源。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 persistence.xml 应用程序中添加非 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：

我在 OpenSuse 上尝试了相同的配置，它在那里工作。我发现的唯一区别是 SLSE 已经从 IBM 安装了 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？
