我必须从 Tomcat 6 连接到 Oracle 12c 数据库。我创建了一个 servlet 来创建与该数据源的连接（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。

我正在使用ojdbc6.jarOracle 12c、Tomcat 6、Java 1.6、Windows 7 的驱动程序。有人有一些提示吗？

您可能已经在服务器上的 sql.net ora 文件中设置了 SQLNET.ALLOWED_LOGON_VERSION。

我决定迁移到 Tomcat 7。

对我有用，但使用参数SQLNET.ALLOWED_LOGON_VERSION_SERVER

我将其设置为 8 以确保。

请参阅文档：http ://docs.oracle.com/database/121/NETRF/sqlnet.htm#NETRF2016
