I am facing the same issue as this thread:
https://web.liferay.com/community/forums/-/message_boards/message/67678964I cannot figure out how to load journal article.
<div>
<%
JournalArticle article = JournalArticleLocalServiceUtil.getLatestArticleByUrlTitle(themeDisplay.getScopeGroupId(), "chaingeneralaccountinfo", 0);
%>
<liferay-ui:journal-article articleId="<%= article.getArticleId() %>" articleResourcePrimKey="<%= article.getResourcePrimKey() %>" groupId="<%=themeDisplay.getScopeGroupId() %>" languageId="<%=themeDisplay.getLanguageId() %>" showAvailableLocales="<%=false %>" />
</div>
