Class Include

java.lang.Object
  org.apache.struts2.components.Component
      org.apache.struts2.components.Include

public class Include
extends Component

Include a servlet's output (result of servlet or a JSP page).

Note: Any additional params supplied to the included page are not accessible within the rendered page through the <s:property...> tag since no valuestack will be created. You can, however, access them in a servlet via the HttpServletRequest object or from a JSP page via a scriptlet.

• value* (String) - jsp page to be included

Examples

 
 <-- One: -->
 <s:include value="myJsp.jsp" />

 <-- Two: -->
 <s:include value="myJsp.jsp">
    <s:param name="param1" value="value2" />
    <s:param name="param2" value="value2" />
 </s:include>

 <-- Three: -->
 <s:include value="myJsp.jsp">
    <s:param name="param1">value1</s:param>
    <s:param name="param2">value2</s:param>
 </s:include>
 

 
 Example one - do an include myJsp.jsp page
 Example two - do an include to myJsp.jsp page with parameters param1=value1 and param2=value2
 Example three - do an include to myJsp.jsp page with parameters param1=value1 and param2=value2
