resin中javabean的问题
(iis4 + nt4 +resin1.2.1)
resin可识别javabean,(c:/inetpub/wwwroot下建web-inf/lib,将javabean包放到lib下)
但http://localhost:8080/login.jsp ---->调login_handle.jsp 出错如下:
500 Servlet Exception
java.lang.NullPointerException:
at _jsp._login_0handle__jsp._jspService(c:/inetpub/wwwroot/login_handle.jsp:20)

5> Resin在IIS中的安装配置
IIS WEB以其管理操作简单和对ASP的支持而受不少人的喜欢。这里介绍怎么用resin使IIS支持jsp和servlet。
一、分别安装配置iis和resin1.1使各自都单独能正常运行。iis和resin1.1的安装后路径如下：c:/apache (* 注：这里应为c:/inetpub)和 c:/resin1.1。
二、配置IIS
1.拷贝iis_srun.dll 到IIS scripts目录"c:/inetpub/scripts";
2.在c:/inetpub/scripts目录下创建配置文件(resin.ini)用于指定resin的配置文件的位置。
resin.ini内容如下：
CauchoConfigFile c:/resin1.1/conf/resin.conf
三、配置resin
<caucho.com>
<http-server app-dir='C:/Inetpub/wwwroot'>
<servlet-mapping rl-pattern='/servlets/*' servlet-name ='invoker'/>
<servlet-mapping rl-pattern= '*.xtp'ervlet-name= 'com.caucho.jsp.XtpServlet' />
<servlet-mapping rl-pattern='*.jsp' servlet-name= 'com.caucho.jsp.JspServlet' />
</http-server>
</caucho.com>
四、测试
1、 运行IIS,启动resin的jsp引擎（运行c:/resin1.1/bin/srun.exe）
2、 把一个jsp文件(test.jsp )放入IIS的C:/Inetpub/wwwroot目录下.
test.jsp如下：
<%@ page language=java?> (* 注：这里似乎应为"%>")
2+2=<%=2+2%>
浏览http://localhost：port/test.jsp。你将看到：2+2=4<——这个结果
注：port为端口号，调试环境nt4.0+iis+resin1.1

jrun3与resin1.2.1
我的目的:在iis下可同时用asp及jsp
jrun3开发版有限制(最多3个jsp)
resin1.2.1界面不好
其它方法?
可否看看我近期帖出的文章?
******************************************************
jrun3 enterprice我安装成功(用8000不行)
但它会过期! 开发版又不成功!
jrun3 enterprice及开发版大小一样???
仅由系列号决定?
不知可否请你try jrun开发版?
我只想有同时support asp&
jsp,其它的工具?
可否请你帮一把!

Edition of JRun.似乎有问题，后重装（仅要jsp),结果一样！
另down jrun3 developer时， 无系列号（从mail)，用 JR300P1-0103-2343-7518，可否？
(而down jrun3 enterprise后,allaire email 系列号 )
到底问题出在哪,有诀窍?
