jsp页面 form action="add_role.action" method="post">

RoleAction的添加方法
public String add_role() throws Exception {
System.out.println("----------");
Role role = new Role();
role.setName(name);

roleservice.addRole(role);
return "add_success";
}


页面报错：
HTTP Status 404 - There is no Action mapped for action name add_role.

<package extends="alveole-defaults" />
我一直写的是<package extends="struts-default" />

[cascada]

struts.xml
如下 <struts>
<include file="alveole-defaults.xml"/>
<include file="alveole-struts.xml"/>
</struts>

alveole-default.xml

如下
<struts>
<package name="alveole-defaults" extends="struts-default">
</package>
</struts>
这样写没有问题吧

<form action="/add_role.action"> 试试

[redlotus_lyn]

add_role请求所在命名空间是根命名空间(/)
你的页面add_role请求在默认命名空间("")

<s:form name="add_role" namespace="/">

[redlotus_lyn]

上面写错了，应该是下面的写法
<s:form action="add_role" namespace="/">

[quxiuer]

form标签中添加namespace="/"
