Defined jsp include action tag ?

The <jsp:include> element allows you to include either a static or dynamic file in a JSP file. The results of including static and dynamic files are quite different. If the file is static, its content is included in the calling JSP file. If the file is dynamic, it acts on a request and sends back a result that is included in the JSP page. When the include action is finished, the JSP container continues processing the remainder of the JSP file.
syntax of include action Tag:
<jsp:include page="relativeURL" flush="{true|false}" />
<jsp:include page="index.jsp" flush="true" />
