Answer 1

我觉得是数据库数据的问题吧
NullPointerException 指明是将一个值为null的变量非法使用了
test_jsp.java:55指明了在%tomcat_home%\work下找到该应用对应的servlet
在test.jsp对应的test_jsp.java的55行出错

Answer 2

请安装SQL SP3 或SP4补丁，然后再试试。
还有TOMCAT5.X应该是配JDK1.5

Answer 3

SQLSERVER2000安装时有版本的区别
WIN2000下面可以装企业开发版，也就是说可以作为服务器也可以作为客户端主机．但是在XP下面只能装个人版，不可以做网络服务器．
