我已经把3个sqlserver的驱动拷到/web-inf/lib下,在jre/lib/ext下也拷进去了，并且在java build path-library-add external jars也包含进这3个jar了。为什么还报错？开发工具是eclipse
DataBaseConnection.java
import java.sql.Connection;
import java.sql.DriverManager;
public class DataBaseConnection {
public static Connection getConnection(){
Connection con=null;
String CLASSFORNAME= "com.microsoft.jdbc.sqlserver.SQLServerDriver ";
String SERVANDDB= "jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=jspdev ";
String USER= "bn ";
String PWD= "bn ";
try{
Class.forName(CLASSFORNAME);
con=DriverManager.getConnection(SERVANDDB,USER,PWD);
System.out.println( "connect success ");
}catch(Exception e){
System.out.println( "connecting failded ");
e.printStackTrace();
}
return con;
}
}
------解决方案--------------------
补丁呢?

我已经打了sp4的补丁了,可还是这样,看了不少关于这个问题的帖子,有些错误差不多,但修改后还是这样
------解决方案--------------------
版本不对吧.
看你用的是2000还是2005了,下个合适的驱动. 2005好像一个驱动文件就行了.
