您好：
第10章博客网站jar包需要4个，分别是msbase.jar,msutil.jar,mssqlserver.jar,jspSmartUpload.jar；
但是从网站下载的jar包只有sqljdbc.jar和jspSmartUpload.jar包。当登陆博客网是，出现下面的错误，请帮助解答，谢谢。
HTTP Status 500 -

java.lang.NullPointerException

Apache Tomcat/6.0.29
另外我发现JDBCconnection.java 代码中有如下代码
public class JDBConnection {
private final String url = "jdbc:sqlserver://192.168.1.199:1433;DatabaseName=db_BlodMay";
private final String userName = "sa";
private final String password = "111";
private Connection con = null;
和视频中说的密码为空和localhost不一致！ 请给出解决的办法，谢谢。
