jsp连接ORACLE9I失败,请前辈帮忙
开发环境:TOMCAT5.0.30+ORACLE9I+JDK1.4
IP:192.168.100.89
数据库的SID:myoracle
SQLPLUS启动正常,TOMCAT与JSP运行正常.
用网上常用的JDBC连接ORACLE的例子进行测试连接,代码如下:
<%@ page contentType= "text/html;charset=gb2312 "%>
<%@ page import= "java.sql.* "%>
<html>
<body>
<%Class.forName( "oracle.jdbc.driver.OracleDriver ").newInstance();
String url= "jdbc:oracle:thin:@china3ct:1521:myoracle ";
String user= "system ";
String password= "zong ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from scott.dept ";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
<%=rs.getString(1)%> - <%=rs.getString(2)%> <br>
<%}%>
<%out.print( "数据库操作成功，恭喜你 ");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
出现如下错误:
