Hi Team,
I have Created two modules(First and Second) and I  embedded the first  module  into second module using "Portlet run time tag".
But The problem is render URL which is  there in first module not working.So could you guys help me.

Here is the code :

First Module:
<liferay-theme:defineObjects />
<portlet:defineObjects />
 <portlet:renderURL var="url1"></portlet:renderURL>
 <a href="<%=url1%>">Clik me</a>
Second Module:
<liferay-theme:defineObjects />
<portlet:defineObjects />
<liferay-portlet:runtime  portletName="firstmodule"   /> Regards,
P.V.B.Raju.
