In my application, many jsp files include the header.jsp to display the head.
There are two ways, both static include and dynamic include.
The static include is <%@ include file="/jsp/header.jsp" %>.
The dynamic include is <jsp:include page="/jsp/header.jsp" flush="true">.
There was a requirement to update the header.jsp and every page that includes the header needs to display the new header.
It seems that I just need to deploy the updated header.jsp. But that doesn't work due the web container setting.
I also need to re-deploy all those includer jsp files to make sure their time stampt is more recent then the header.jsp.
That caused a big maintenance problem.
I am not very sure if the web container is Sun iPlanet.
Do you have any comments for the sustain?
