jsp连接数据库出的问题
我连接的是sqlserver2000.我的程序中数据库连接的代码如下:
String MapID = request.getParameter( "MapID ");
String MapFileName= " ";
int NumOfWarehouses=0;
System.out.println(MapID);
DBConnect.dbconnect = new DBConnect();
boolean isconnect = dbconnect.connect();
出错的提示如下 ：
HTTP Status 500 -

[解决办法]
DB这个包不存在.可能是你引包的时候包名出现错误.DBConnect该类没有引进来.你好好的检查DBConnect存在的位置.重新引入DBConnect试试看.
