Thank you so much!

You'll need to find a graphing or charting package that can produce what you want.

Could you please explain your idea clearly?
In my opinion, I want to build a tree node look like this:
public class Node {
public int uniqueId;
public int parentId;
public String name;
public List<Node> children = new ArrayList<Node>();
public List<Node> parent = new ArrayList<Node>();
}

And Data table used to create chart as below:
UniqueId | ManagerId | Name

1 0 CEO
2 1 Director 1
3 1 Director 2
4 1 Director 3
5 3 Manager 1
5 4 Manager 1
6 2 Manager 2
7 2 Manager 3
8 2 Manager 4
9 5 Worker 1
10 5 Worker 2
11 6 Worker 3
11 7 Worker 3
11 8 Worker 3
12 6 Worker 4
12 7 Worker 4
12 8 Worker 4
13 6 Worker 5
13 7 Worker 5
13 8 Worker 5

But i don't know to render this chart to JSP by using struts tag?

You can't. There is nothing in JSP or Struts to do this. As I said, you'll need to find a product that can do this for you.

Or using technology like in the other questions on this same matter that you have posted (Flex, JavaFX, etc)

Thank you, I'll find a new way to resolve this problem.
