java连接Oracle数据库

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JavaOracle {
public JavaOracle() {
}

public static void main(String[] args) {
   try {
    try {
     Class.forName("oracle.jdbc.driver.OracleDriver");
    } catch (java.lang.ClassNotFoundException e) {
     System.err.print(e.getMessage());
    }
    String url = "jdbc:oracle:thin:@192.168.1.108:1521:hqh";
    Connection conn = DriverManager.getConnection(url, "scott", "tiger");
    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("select * from emp");
    while (rs.next()) {
     System.out.println(rs.getString("ename"));
    }
    conn.close();
   } catch (SQLException ex) {
    while (ex != null) {
     System.out.println(ex.getSQLState());
    }
   }
}
}

别忘了到D:\oracle\ora92\jdbc\lib下把驱动classes12.jar放进去哦 ！
