Web content data display in custom-portlet

Many more time during development we need display liferay web-content in our custom-portlet.
Liferay taglib already give tag to display web-content data.

Here is syntax for "<liferay-ui:journal-article/>"

<<liferay-ui:journal-article showTitle="true/false" articleId="longArticleId" groupId="longGroupId" />


Let take an example...

<<liferay-ui:journal-article showTitle="false" articleId="<%= journalArticleId%>"
groupId="<%= themeDisplay.getScopeGroupId() %>" />

here journalArticleId is long var which is articelId of web-content
