Hi,
Can some one help me with this issue, I have a JSP page with 3 buttons, Add, Create and Cancel, and three columns, one with dropdown list. This list i should get from database table. First time when i deploy this page, initially row is getting this dropdown list from table. But when i click on add button, it is not getting any drop down values.
Here is my JSP code:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">;

height: 100%;
float: left;
overflow: hidden;
align: top;
vertical-align: top;
}
</style> --%>
