I'm using Display Tag Library for paging the result of my table in a
jsp file.I can get my table to display, but the column 'sort' url
keep taking me out of the portal environment. I tried the following
solution, but it didn't work either:

<Portlet:defineObjects />

<display:table name="TestList" id="test" requestURI="<%
=renderResponse.createRenderURL().toString() %>" >
