function is not working i am stucking where am doing wrong Please help me i think there is minor mistake so i Could not able to find that Error . 函数无法正常工作我在哪里做错了请帮我，我认为这是一个小错误，因此我无法找到该错误。

Answer 1

The form is submiting an action name as addUsermenu . 表单正在将操作名称addUsermenu为addUsermenu 。

In your struts.xml, you have an action tag to point to all the methods , that matches *menu. 在struts.xml,您有一个动作标签来指向与* menu匹配的所有方法。 So your addUsermenu will find its corresponding method. 因此，您的addUsermenu将找到其对应的方法。 ie addUser(). 即addUser（）。

But in the case of delete you must change the action name to deleteUsermenu inorder to find the function deleteUser() 但是在删除的情况下，必须将操作名称更改为deleteUsermenu才能找到函数deleteUser()

Solution Change the delete Link to this 解决方案将删除链接更改为此

<a href="delete">Delete</a>

to this 对此

<a href="<s:url action='deleteUsermenu'/>">Delete</a>
