首先在这里先对您说声谢谢!呵呵~~~

今天我又重按照光盘使用说明书里的步骤试了一次,,,,上面六步顺利,对了我安装了sp4补丁(我安装的是Sqlserver2000的sp4补丁,为什么

我查看添加\删除程序里面看到的却是MSXML 4.0 sp2呢!在SQL企业管理器查询显示是SP4.)

到了第七部如果没有密码的话就连接不上localhost所以我把Tomcat安装目录Con文件夹下的tomcat-users.xml文件的内容

改为了 
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<user username="tomcat" password="tomcat" roles="tomcat,manager"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
</tomcat-users>
此时,我可以连接上localhost了,但当我点击进入Tomcat管理界面下的“marketplace”超链接时,却不能进入“marketplace”程序中。

而且出现了这样的问题:HTTP Status 500 -
