O.K. It works.
But if I use <jsp:setProperty name="h" property="User" value="new user" />
It doesn't work again.
The error said: javax.servlet.ServletException: Can't find method for User
But if I use <% h.setUser("new user") %>, it works.
Is it a bug ? or somethins wrong in jsp:setProperty tag ?
Thanx
Best Wishes
