jsp连接ORACLE的问题！急！

JSP程序如下：
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="JAVA.sql.*"%>
<html>
<body>
<%Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:oracname";
//orcl为你的数据库的SID
String user="orac";
String password="dsgdsf";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from usss";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为：<%=rs.getString(1)%>
您的第二个字段内容为：<%=rs.getString(2)%>
<%}%>
<%out.print("数据库操作成功，恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>

要要oracle驱动包,你可以去ORACLE下载.
在oracle安装目录里找classes12.jar放到你的lib里
classes12.jar 这个包我加上了，还是不行……

还有TOMCAT 里面提示：
WebappClassLoader: validateJarFile(F:\web\WEB-INF\lib\servlet-api.jar) - j
