【问题描述】：
我必须从 Tomcat 6 连接到 Oracle 12c 数据库。我创建了一个 servlet 来创建到该数据源的连接（来自 META-INF/context.xml）：
<Context debug="0" docBase="/Test" path="/" reloadable="true">
<Resource
name="jdbc/test" auth="Container" type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@somewhere:someport:someservice"
username="someuser" password="somepass" maxActive="10" maxIdle="5"
maxWait="5000" removeAbandoned="true" removeAbandonedTimeout="60"
logAbandoned="true"
/>
</Context>
当我使用此代码创建连接时：
InitialContext initContext = new InitialContext();
Context ctx = (Context) initContext.lookup("java:comp/env");
DataSource ds = (DataSource) ctx.lookup("jdbc/test");
conn = ds.getConnection();
我得到以下异常：

但是用这段代码创建连接
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@somewhere:someport:someservice", "someuser", "somepass");
工作正常；此外，如果我在 servlet 中使用指向 Oracle 11g 数据库的 URL，它就可以工作。
我正在为 Oracle 12c、Tomcat 6、Java 1.6、Windows 7 使用 ojdbc6.jar 驱动程序。有人有一些提示吗？
