Creating render urls to link between pages in a community in Liferay

I've set u开发者_运维百科p a Liferay community, along with a number of pages each defining there own set of portlets, themes and layouts. I want to be able to create links between these pages. For example given that I am at the top level page (lets call this 'home'), I want to link to another page (for example 'blog') from within one of my portlets.

Is there a way, either using the Liferay or Portlet APIs to create a render url based on a page parameter that I supply. As far as I can see, the liferay-portlet-ext taglib defines a renderUrl tag that I can use to create a URL that links back to the same page, however I can't see a way to specify the page name in this tag.

I'm using Liferay 5.2.3. Thanks in advance.

You can either link them with friendlyURLs (/web/othergroup/blog) or you can use

PortletURL portletURL = PortletURLFactoryUtil.create(
    request, portletName, plid, ‎lifecycle);‎
