我想在java web应用程序中连接到数据库.我在servlet中编写了这段代码,我添加了相关的jar文件(ojdbc),但是当我运行它时,它给了我这个错误:java.lang.ClassNotFoundException:oracle.jdbc.driver.一个OracleDriver

public class DBConnection extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public DBConnection() {
        super();
        // TODO Auto-generated constructor stub
    }

    public void service(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {

        Connection con = null;  

        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
              con = DriverManager.getConnection("jdbc:oracle:thin:@192.168.101.84:1521:orcl","XXXX","XXXX");
              if(con!=null)
                 System. out.println("Connection Successful");
              else
                  System.  out.println("error");

        }
        catch (Exception e) {
            //System.out.println(e);
        }
...

我该怎么办？

我有一个ORACLE RAC环境访问.详情是

数据库名称:orcl服务名称:orcl IP地址:192.168.1.1和192.168.1.2

SQL> host srvctl status database -d orcl

Instance orcl1 is running on node orclnode1

Instance orcl2 is running on node orclnode2

我关心的是我的联系,正在建立使用

(DESCRIPTION=(ADDRESS=
    (PROTOCOL=TCP)(HOST=192.168.1.1) (PORT=1521)
)(CONNECT_DATA=(SID=orcl1)))

但是提供者希望它通过orcl服务名称连接.

我没有任何其他与此相关的信息.我是否正确连接或者我需要orcl服务名称的主机名或IP地址.
