Как получить вебконтент

В Java:

String xmlRequest = PortletRequestUtil.toXML(request, response);

ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
JournalArticleDisplay articleDisplay = JournalContentUtil.getDisplay(
            themeDisplay.getLayout().getGroupId(),
            articleIdStr,
            null,
            themeDisplay.getLanguageId(),
            xmlRequest);
articleDisplay.getContent();

В JSP:

<%@ page import="com.liferay.portal.kernel.util.WebKeys" %>
<%@ page import="com.liferay.portal.theme.ThemeDisplay" %>

<liferay-ui:journal-article articleId="${articleId}"
                                                groupId="<%= ((ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY)).getPortletGroupId() %>"/>
