Hi Omkar,

Communication between two portlets can be done using IPC.
Check this link
and this wiki.

If i want to Portlet Session to send parameter then..

How can i use Portlet session in javascript function
to set parameter using seAttribute() function of PortletSession.??

Hi,
You can't do it directly. Becouse session are controlled by server and
javascript runs client side.

Try by using HttpRequest to get the parameter from URL.

HttpServletRequest httpRequest = PortalUtil.getHttpServletRequest(request);
httpRequest = PortalUtil.getOriginalServletRequest(httpRequest);
httpRequest.getParameter("myParameter");

Hi Jitendra,

It worked for me Thanks.
i am able to read url parameter using code given by You.

I have only added following two lines in liferay-portlet.xml file.

<private-request-attributes>true</private-request-attributes>
<private-session-attributes>false</private-session-attributes>

It doesn't work without these for me.

Thank You very much.

For private-request-attributes by default it is true only and you are setting and getting parameter from request so it should work even if don't set private-request-attributes to true.

<!--
Set the private-request-attributes value to true if the portlet does not share
request attributes with the portal or any other portlet. The default value is
true. The property "request.shared.attributes" in portal.properties specifies
which request attributes are shared even when the private-request-attributes
value is true.
