struts异常There is no Action mapped for namespace [/] and action name [] ......
我用的maven项目管理，这个问题是用jetty服务器出的，tomcat可以正常运行跑通。之前tomcat也出现这个问题，后来不知道不知不觉也就没这问题了，昨天换jetty容器了，问题重现，我估计还是当初配置的问题，或是什么命名空间的原因，找了半天没找到，所以求助大家。
下面是我的web.xml
<?xml version="1.0" encoding="UTF-8"?>

然后是我的struts.xml

我调用action的时候就会出问题，具体错误如下

求助如何解决这个问题，配置出错了没有？还是什么其他原因？ 异常 Struts 命名空间 namespace action
[解决办法]
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
重复配置，保留/*那个就可以了，同时请楼主贴出调用的代码啊
[解决办法]
action的路径错误，前后命名空间namespace的值不一致
[解决办法]
试下这样可以不<package name="str" namespace="/" extends="struts-default">
[解决办法]
赞同楼上
[解决办法]
或者找到对应的的jsp页面，<form action="xxx" method="post" namespace="">这里的namespace要和<package name="str" namespace="" extends="struts-default"> 一致
[解决办法]
lz要明白你测试时请求的url是什么？同时你在web.xml中配置的url映射/*，会拦截所有的请求，包括静态资源访问。所以就会报action name找不到这类的错误
你是在点击登陆报的错误呢，还是后台方法已经运行了，但是在界面渲染的时候报的错误呢
还有你的jsp代码最好也晒晒
[解决办法]
Could not find action or result
/
这里请求的action的name竟然是/
你发一下你的jsp页面代码。
form表单肯定填的有问题
