No. of outstanding tasks/New tasks in UWL

Question

Hi Experts,
I need your help in showing the number of outstanding tasks and number of new tasks  that are coming in UWL in portal home page.
I need to develop one par file in achieving this. Can you please let me know what services I need to use to get those details.
I need only the number of outstanding tasks and number of new tasks , but not actual task details.
Thank you,
Raghavendranath G

It could be something like:
<%@ page import = "java.util.HashMap"%>
<%@ page import = "com.sap.netweaver.bc.uwl.Item" %>
<%@ page import = "com.sap.netweaver.bc.uwl.UWLException" %>
<%@ page import = "com.sapportals.portal.prt.component.IPortalComponentRequest" %>
<%@ page import = "com.sapportals.portal.prt.component.IPortalComponentResponse" %>
<%@ page import = "yourCompany.FrameworkUtils" %>
<%@ page import = "yourCompany.UWLHelper"%>
<%
    try {
        SafeResourceBundle safeBundle = FrameworkUtils.getFrameworkSafeResourceBundle(componentRequest.getLocale());
        HashMap tasks_counter;
        UWLHelper uwl_helper = new UWLHelper(componentRequest);
        tasks_counter = uwl_helper.getUWLItemCounter();
        String itemDetailsLink = componentRequest.getComponentContext().getProfile().getProperty("uwl_path");
        String linkToDetailPage="<a href='" + itemDetailsLink + "'>";
        if (tasks_counter.size() != 0) {
%>
<!-- heading -->
<div class="heading">
<h2><%=safeBundle.getSilent("widget.worklist.my_tasks")%></h2>
