我的环环境是windows2003+tomcat5.5+jdk1.5+mssql
我已按要求装好了以上软件,并且http://localhost:8080访问可以显示大花猫了,说明安装成功,可是我把我的程序考在root目录下,运行没有涉及到数据库的地方都会正确,但运行到有涉及连接数据库的地方就会出错,这是为什么呢?我是这样连库的:
public class dbconn {
string dbdriver = "com.microsoft.jdbc.sqlserver.sqlserverdriver ";
string strcon = "jdbc:microsoft:sqlserver://localhost:1433;databasename=uplifeoa ";
string user = "sa ";
string pass = "111 ";
connection con = null;
resultset rs = null;
statement stmt = null;
public dbconn（) {
try
{
class.forname（dbdriver);
}
catch （java.lang.classnotfoundexception e)
{
system.err.println（ "数据库驱动程序加载失败，异常为： "+ e.getmessage（));
}
finally
{
system.out.println（ "驱动程序加载成功 ");
}
}
连接的帐号密码肯定不会错,我的jsp以前是有正常运行过的,只是重装过后,配置不起来了,我是把我以前所有那程序考到root目录下的,当运行到有涉及到连接数据库如登陆页面时就会报如下错误:

真是奇怪,连接密码肯定不会错,jsp也肯定装成功了,那还差什么呢?
