JSF subview Tag
This tag is used to create the sub-view of the view. It contains all JSF tags in a page that is included in another JSP page. It acts as a naming container so that the components inside it can be made unique. This naming container contains JSF tags on a nested page by <jsp:include> or the tag which includes the page dynamically. To include another JSP or JSF page, using <jsp:include> or <c:import>, we must use <f:subview> tag around it so that JSF process the included file properly. subview.jsp is the main page where subview tag is used to include next.jsp page.
