无法从Tomcat 6连接到Oracle 12c 6：没有匹配的身份验证协议（ORA-28040）

我必须从Tomcat 6连接到Oracle 12c数据库。我创建了一个与此数据源建立连接的servlet（从META-INF/context.xml）：无法从Tomcat 6连接到Oracle 12c 6：没有匹配的身份验证协议（ORA-28040）

<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>

当我创建使用此代码连接：

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：

    ... 18 more

但是创建与此代码

Class.forName("oracle.jdbc.driver.OracleDriver"); 
conn = DriverManager.getConnection("jdbc:oracle:thin:@somewhere:someport:someservice", "someuser", "somepass");

连接工作正常;此外，如果我在servlet中使用Oracle 11g数据库的URL，它就可以工作。

我正在使用ojdbc6.jar驱动程序为Oracle 12C，Tomcat 6，Java 1.6，Windows 7.任何人都有一些提示？
