就是加注示的三行有错，

ConDB.java

}

return pstmt;

return rs;

return rs;
}
// public ResultSet getpstmtrs() throws Exception{

}

没贴出其它两个文件，太长了

就是这个ConDB.java有错

不知道怎么解决这个问题

系统重做的，SQL重装了，eclipse没重装,数据源也建了，库也导入了，SQL中的安全性也改为

SQL Server和window

[malligator]

数据源名字对么?

测试连接能连么?

用户名密码也对吧?

[zkm2004]

重装了系统，程序不变，我直接把数据源的名字贴过去的，没错

测试能连接

用户名用的是sa

密码为空

都和以前一样

[pdskiller]

你的包都有吗？
得装后，JDK还在原来的地方吗？

[zkm2004]

谢谢大家了，我自己搞定了，

重装后，jdk要访问网络，我给屏蔽了，我允许它访问网络，就ok了

[tcmis]

呵呵，，防火墙

恭喜lz
