Question

I am referring to a url which has paramID from my portlet. The content of that paramID is handled in different portlet and it has its own controller.

That controller is taking HttpServletRequest to read that param.

HttpServletRequest request = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(renderRequest));
String paramID= request.getParameter("paramID");`

My param is in the url http://mysite.com?paramID=123

Will the HttpServletRequest read this param when I am calling using renderURL

<liferay-portlet:renderURL var="xyz" portletName="ABC" windowState="Normal"/>
...
<a href="xyz?pramID"> Click here</a>

Answer 1

I did it with providing the param value while I invoked the renderURL

<liferay-portlet:renderURL var="xyz" portletName="ABC" windowState="Normal"/>
</liferay-portlet:renderURL>

…..

<JAVASCRIPT>
   var URL = NULL;       
   function(called){
          URL = "${xyz}&paramID=123"              //and this was read as servlet param
   }
</JAVASCRIPT>
