u can use URL generation tag given below which calls the portal pages directly and in turn loads the portlets in it.
Tag syntax
<wps:urlGeneration
contentNode="<%=destinationPage%>" portletWindowState="Normal">
<wps:urlParam name="reset" value="Y" />
<a
href="<% wpsURL.write(out); %>" ><fmt:message
key="label" /></a>
</wps:urlGeneration>
