There's a couple of issues with this. First, a portlet only produces page fragments, you can't use <html>, <head> or <body> tags. So you'll have to find another way to refresh the page. Second, the url-tag needs a specified action to produce a correct URL in a portlet environment (there's a JIRA ticket for using the executing action if no action is specified, but this hasn't been implemented yet). Try using <s:url action="longProcess3"/> instead.
