From source file:org.jasig.portlet.proxy.service.proxy.document.HeaderFooterFilter.java

@Override
public void filter(Document document, IContentResponse proxyResponse, RenderRequest portletRequest,
        RenderResponse portletResponse) {

    // get any configured header / footer content from the portlet preferences
    final PortletPreferences preferences = portletRequest.getPreferences();
    final String header = preferences.getValue(HEADER_KEY, null);
    final String footer = preferences.getValue(FOOTER_KEY, null);

    // If both a header and footer have been specified, there's some chance they 
    // could be intended to wrap the proxied content.  We can't wrap content 
    // using the prepend / append methods, since those would automatically 
    // close partial elements in each header / footer
    if (StringUtils.isNotBlank(header) && StringUtils.isNotBlank(footer)) {
        document.html(header.concat(document.html()).concat(footer));
    }//from   ww w .ja  v  a2s. c o  m

    else if (StringUtils.isNotBlank(header)) {
        document.prepend(header);
    }

    else if (StringUtils.isNotBlank(footer)) {
        document.append(footer);
    }
