Web Content Display portlet to display article dynamically - Liferay

Problem: I want to use web content display portlet to display articles dynamically  (i.e) I will pass article-id as an argument to page and web content display portlet has to read the article-id and display the content.

Solution: 
The above problem can be solved by creating an template. Have the below script in your template.
Sample URL for page would be http://localhost:8080/web/carlovers/dynamic-page?articleId=10712

 
## Get Article Id from the request URL
#set ($current_url = $request.get("attributes").CURRENT_COMPLETE_URL)
#set ($paramName='articleId')
#set ($articleId = $httpUtil.getParameter($current_url, $paramName))
#set ($journalArticleLocalService = $serviceLocator.findService("com.liferay.portlet.journal.service.JournalArticleLocalService"))
## Get article based on article id
#set ($article = $journalArticleLocalService.getArticle($getterUtil.getLong($request.theme-display.scope-group-id),$articleId))

## display relavent information
$article.getUrlTitle()
$article.getContentByLocale($request.theme-display.language-id)
