快疯了，怎么老是出这个问题啊？
高手指点一下吧
下面是代码和错误提示

[解决办法]
web.xml
/Web-INF/...
==>
/WEB-INF/...
[解决办法]
原因有很多种
1。Web.xml未初始化问题
少了一个 <load-on-startup> 0 </load-on-startup>
这样开始是没有加载这个类，就没有初始化struts-config.xml，所以找不到
actionmappings or actionformbeans collection。
2。struts-config.xml问题
3。jar包不全或版本不对
也有可能导致这个问题，从stuts例子里面拷过来就好了。struts1.1自带共10个jar包。
4。编译问题
有可能Action和Formbean没有编译，也会有这个问题，检查一下有没有对应的class文件就好。class路径不对可能也会导致这个问题。
5。版本问题
用的servlet容器和struts版本不对或这两个版本协调有问题。
在以上几条都不能解决问题的情况下，可能就是版本的问题了，换个高版本试试吧
我认为LZ问题可能是版本问题
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.1//EN "
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd ">
换成
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN " "http://struts.apache.org/dtds/struts-config_1_2.dtd ">
or把WEB.xl
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN " "http://java.sun.com/dtd/web-app_2_3.dtd ">
改为
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN "
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd ">
[解决办法]
将jsp页面中的 <html:form action= "/LogonAction " focus= "userid ">
改为 <html:form action= "LogonAction.do " focus= "userid ">
或 <html:form action= " <%=request.getContextPath()%> /LogonAction.do " focus= "userid ">
可以一试,我也说不清楚
[解决办法]
<form-beans>
<form-bean name= "userForm " type= "user.UserForm "/>
<form-property name= "userid " type= "java.lang.String " />
<form-property name= "pwd " type= "java.lang.String " />
</form-beans>
to :
<form-beans>
<form-bean name= "userForm " type= "user.UserForm ">
<form-property name= "userid " type= "java.lang.String " />
<form-property name= "pwd " type= "java.lang.String " />
<form-bean />
</form-beans>
[解决办法]
啊,错了,是:
<form-beans>
<form-bean name= "userForm " type= "user.UserForm ">
<form-property name= "userid " type= "java.lang.String " />
<form-property name= "pwd " type= "java.lang.String " />
</form-bean>
</form-beans>
