I am trying to pass parameter from servlet to a particular portlet on portal page.

I am using engine URL for this purpose.What I want is to get the parameter in process action of portlet from the servlet.

I am able to get the parameter in do view of the portlet but I am unable to get it in the process action.

I followed the same steps in portal 6.0 and I am able to get the parameter in the process action but when I am trying to do that in the wps 6.1, I am not able to get that in process action.

Any idea ?? why ??
