include directive vs standard action

[Shiaber Shaam]

Why include directive is said to be not dynamic?

In HFSJ, they are referring to rollit function and they are trying to say dynamic and in the place where they are explaining params, they tell that it doesnt apply to directive as it is not static?

Please clarify.

hi,

   
     <%@ include file="myjsp.jsp?key=value"%>
 

this is static include ,here you can not pass parameter to the include page but you can do this in <jsp:include page="myjsp.jsp?key=value"/> this is dynamic inclusion

I wanted to post a trivial doubt on same topic jsp:include Vs @ include.

A.jsp

<%@ page isELIgnored=false %>
The current date and time are: 
<%@ include file="B.jsp" />

C.jsp

The current date and time are: 
<jsp:include page="B.jsp" >
</jsp:include>

B.jsp

<%@ page import="java.util.*" %>

<%= (new java.util.Date() ).toLocaleString() %>

Now As HFSJ mentions that @ include does everything @ translation time i.e. it copies code of B.jsp into A.jsp and then created instance of servlet A. As such it is more often used for pages which are not updated regularly.

<jsp:include> on the other hand includes a runtime call for B.jsp inside A.jsp and with every request accesses output of B.jsp @runtime.

But in this case how would the difference between jsp:include and @include play out for two subsequent requests to A.jsp and C.jsp??

As per my understanding display would be different for each subsequent request to A.jsp or C.jsp.

Display @ FIRST Request Call to A.jsp ====>

The current date and time are

Feb 27, 2009 21:38:40


Display @ SECOND Request Call to A.jsp ====>

The current date and time are

Feb 27, 2009 21:40:40


Display @ FIRST Request Call to C.jsp ====>

The current date and time are

Feb 27, 2009 21:42:40


Display @ SECOND Request Call to C.jsp ====>

The current date and time are

Feb 27, 2009 21:44:40


So is the difference only related to static HTML, images etc. ???
