How to get value of generated row value for another action when generated submit button is clicked

I want to know how to get dynamically generated table row value (eg. empp_id) when clicking submit button that is generated for each row dynamically.

Below is my code. I used to generate each row and submit button for each row. I don't know how to use submit button to get and pass the value of 'id' column to another action.

Struts.xml

I need your help please. I can't go any further, i am stuck here.

Solution

When you use <s:property/>, you are not creating a form tag, but just simple text.
To send something printed with <s:property/>, use an <s:hidden/> in conjunction with it.
To send a list of object from JSP, you need to use the IteratorStatus object to specify an index.
You are not even using a form. You need a form to POST something in the standard, non-AJAX way.
You need two action's methods, or two actions: one to display the data, the other to edit it.
In your execute() method you are initializing your list every time:
liUser=new ArrayList<User>();,
so the one coming from the page will always be lost.

You are in deep water. I suggest you to stop for a moment and take a closer look at HTML, HTTP, Struts2 and its tags, otherwise you will get frustrated quite soon.
