Embedding a portlet into the theme, the best way

liferay-portlet.xml

		<add-default-resource>true</add-default-resource>
		<system>true</system>

portal_normal.vm.html

#set ($locPortletId = "82")

##
## Portlet Setup 
## 
## This is for look and feel only. In case of instanceable portlets this 
## is the same as the PortletPreferences.
##
## If you want the PortletPreferences for a non-instancable portlet, 
## you'll have to make a different call.
##
#set ($portletPreferencesFactoryUtil = $portal.getClass().forName("com.liferay.portlet.PortletPreferencesFactoryUtil"))
#set ($portletSetup = $portletPreferencesFactoryUtil.getLayoutPortletSetup($layout, $locPortletId))

#if ($portletSetup.getValue("portletSetupShowBorders", "") != "false")
	#set ($temp = $portletSetup.setValue("portletSetupShowBorders", "false"))
	#set ($temp = $portletSetup.store())
#end

##
## Create the portletURL
## 
#set ($embeddedPortletURL = $portletURLFactory.create($request, $locPortletId, $layout.plid, "RENDER_PHASE"))
## Make sure it's in popup mode, otherwise it doesn't embed nicely.
#set ($VOID = $embeddedPortletURL.setWindowState("pop_up"))
#set ($VOID = $embeddedPortletURL.setPortletMode("view"))
## You can set parameters if you like
##set ($VOID = $embeddedPortletURL.setParameter("some_parameter", "some_value"))

## The iframe. You'll have to set the width of the iframe.
<iframe frameborder="0" id="${locPortletId}custom_frame" src="${embeddedPortletURL.toString()}" scrolling="no" width="50%"></iframe>

## This is the nifty plugin that will proportion the iframe automatically with the height of the content.
## This only works if the portlet is in the same domain as the portal of course.
<script type="text/javascript">
	AUI().use('aui-resize-iframe', function(A) {
		A.one('#${locPortletId}custom_frame').plug(A.Plugin.ResizeIframe);
	});
