Description

We implementing own portlet - this portlet shoudl display web-content by specified articleId.
So, to do it we are using followed code:

<%
JournalArticleDisplay articleDisplay = JournalContentUtil.getDisplay(themeDisplay.getScopeGroupId(), String.valueOf(articleId), null, themeDisplay.getLanguageId(), themeDisplay);
%>

<%= displayArticle == null ? StringPool.BLANK : displayArticle.getContent() %>

this works fine for normal articles - but in case we are trying to display template driven article - we always got null from getDisplay method.

Problem in com.liferay.portal.kernel.templateparser.BaseTransformer class - in method transform it creates templateParser (actually com.liferay.portlet.journal.util.VelocityTemplateParser) with using current thread classloader - which is plugins classloader - and failed (since this class is from portal-impl and not available fro plugins).

To fix this bug we need to use portal's classloader and change code in lines starting from 143 to:

if (Validator.isNotNull(templateParserClassName)) {
TemplateParser templateParser = null;
// Fix for LPS-25992
ClassLoader classLoader =
PortalClassLoaderUtil.getClassLoader();

try

{ templateParser = (TemplateParser)InstanceFactory.newInstance(classLoader, templateParserClassName); }

catch (Exception e)

{ throw new TransformException(e); }
