Answer 1

实在是弄不明白了 昨天在网上找了 好多方法都不行
package com.struts.dao;import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;import com.struts.form.LoginForm;
import com.sun.org.apache.xpath.internal.operations.And;public class ILogincheck implements LoginCheck { public boolean LoginCheck(LoginForm loginForm) {
String name=loginForm.getName();
String password=loginForm.getPassword();
System.out.println(name);
System.out.println(password);
Connection con=null;
Statement st=null;
ResultSet rs=null;
boolean returnk=false;
try {
Class.forName("oracle.jdbc.driver.oracledriver");
con=DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcl", "sysman", "admin");
st=con.createStatement();
String sql="select * from scott.logina where name='"+name+"' And password='"+password+"'";
rs=st.executeQuery(sql);
int k=0;
if(rs.next())
k=k+1;
if(k>0)
returnk=true;
rs.close();
st.close();
con.close();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return returnk;
}}

Answer 2

你看下我的：//我的
Class.forName("oracle.jdbc.driver.OracleDriver");
//你的
Class.forName("oracle.jdbc.driver.oracledriver"); 
大小写看到没有

Answer 3

java.lang.ClassNotFoundException: oracle.jdbc.driver.oracledriver
没找到驱动，
你看看驱动···以及访问驱动字符串···数据库连接字符串···

Answer 4

去下载oracle驱动 没哟驱动肯定会报错的 还有是你的Class.forName("")中间大小写一定分清不能错的 不然很难找出错误的

Answer 5

oracledriver
OracleDriver大小写要写正确  不然肯定是招不到的。
以后不要自己写 要拷贝
