Question

我必须从Tomcat 6连接到Oracle 12c数据库。我创建了一个servlet，用于创建与此数据源的连接（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>

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：

但是使用此代码创建连接

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URL到Oracle 11g数据库，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。任何人都有一些提示吗？

Answer 1

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

Answer 2

我决定搬到Tomcat 7。

Answer 3

适用于我，但使用参数 SQLNET.ALLOWED_LOGON_VERSION_SERVER

我将它设置为8以确定。

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