讨厌的struts,请帮忙！

[tobephonix]

jsp文件中包含一个<html:form>标签，运行时抛出如下异常：

org.apache.jasper.JasperException: Cannot find ActionMappings or
ActionFormBeans collection

整了半天也没有解决掉，请高手帮忙！

tomcat启动时好像没有装入action和formbean,请问这是为什么？

[zzhangwa]

你的web.xml和struts-config.xml没有配置正确吧
具体的要看你的源文件了嘻嘻

This is the Struts configuration file for the example application,
using the proposed new syntax.

NOTE: You would only flesh out the details in the "form-bean"
declarations if you had a generator tool that used them to create
the corresponding Java classes for you. Otherwise, you would
need only the "form-bean" element itself, with the corresponding
"name" and "type" attributes.

建议搂主先对Structs有一个更深的认识。

[tobephonix]

to muskteeeer(跳蚤):身不由己啊，现在是赶鸭子上架，拜托老兄指点一二！

[tobephonix]

异常：Cannot find ActionMappings or ActionFormBeans collection中collection是什么意思，应该是我自己定义的actions和formbeans吧，现在找不到可能有两个原因：
1、程序中引用错误，引用这些actions和formbeans时名称写错了，目前这个原因可以排除，因为我做过检查，而且原来这段程序运行正常，后来也没有做任何改动就不能运行了；
2、tomcat没有装入struts_config.xml文件中的配置信息，这个原因很有可能，因为在tomcat启动时并没有显示装入这些类的信息。
如果是问题2造成的，请问该如何解决。

[tobephonix]

up!

[totyulvxl]

看了楼主的分析,我觉的第二中可能性比较大,
下面的连接可以给你帮助

如果所有的form都不能用肯定是2，
否则，建议检查配置文件，注意 /

[tobephonix]

问题已经解决了,原来WEB-INF/lib下面少了几个与struts.jar关联的包，所以tomcat启动时没有把struts包装入，造成这个问题。
多谢各位，请帮我看看这个更头疼的问题：
