连接数据库的问题

Class.forName()这个方法要抛出异常。需要用try...catch捕获。这个很常见的错误希望你记住，下次不要问这样的问题了，呵呵

我的Class.forName()是在try{}里面啊

我是向远程的oracle数据库导入数据，驱动程序路径应该怎么设置，或者应该把驱动程序拷到那个目录下

你好！adminyefei！ import java.io.*; import java.sql.*; import oracle.jdbc.*; //这一句一定要加！

public class ImportToOracle { public static void main(String[] args) {

try { String sURL = "jdbc:oracle:thin:@127.0.0.1:1521:master "; String sUsername = "scott"; String sPassword = "jacky"; BufferedReader in = new BufferedReader(new FileReader("C:\\BOOTLOG.txt")); //盘符中的文件要存在。 Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); //这一句一定要加！ DriverManager.registerDriver( new oracle.jdbc.OracleDriver()); //这一句一定要加！ Connection conn = DriverManager.getConnection ( sURL, sUsername, sPassword ); System.out.println("connection succeed"); }catch(Exception e) { } } //你下面的我没看。 }
