Maximize a portlet by setting some paramter from Action class   

Hi All
We are using Struts portlet. We need that the jsp to which we are forwarding from action class should be open in Maximize state. For this I think we need to set some parameter in the action class forwarding.

From the jsp if we are caaling any action then we have already set this using
<html:link forward="welcome" windowState="MAXIMIZED"/>

but we want to set this from the action Class as this is the first jsp we are calling from action class.

I read something to use -

com.ibm.portal.struts.common.PortletURIAttributes uriAttributes = new com.ibm.portal.struts.common.PortletURIAttributes();
uriAttributes.setWindowState(javax.portlet.WindowState.MAXIMIZED.toString());
apiUtils.createPortletURIWithStrutsURL(request,"/Welcome.do",uriAttributes);

but I am not sure how to use this to forward to particular action.
If anybody have any idea how to do this Please let me know.

Thanks
