Question

Hi

is there a use of JPF portlet implicit objects
or Portlet Context??

You can use ActionOutput in Controller to push data to JSP page and use pageInput in JSP file to catch that data to display.
For example:
@Jpf.Action(
          forwards = {
               @Jpf.Forward(      
                    name = "index",
                    path = "/tinhvan/portal/index.jsp",
                    actionOutputs = {
                         @Jpf.ActionOutput( name = "userList", required = true, type = java.util.List.class)
     protected Forward begin() {
          usersList = getUsers();
          Forward fw = new Forward("index");
          fw.addActionOutput("userList", getUsers());
          return fw;
<netui:body>
     <netui-data:declarePageInput name="userList" type="java.util.List"/>
        <netui:form tagId="searchForm" action="search" method="post">
                 <netui:select tagId="user" dataSource="actionForm.performedUser" size="1" title="Chọn người dùng cần theo dõi">
               <netui:selectOption value="">-- Xem tất cả --</netui:selectOption>
               <c:forEach items="${pageInput.userList}" var="user">
                    <netui:selectOption value="${user}">${user}</netui:selectOption>
               </c:forEach>
          </netui:select>
        </netui:form>
</netui:body>Regards
