Get journal article urlTitle from the URL

[Hebatu Allah Fahmy, geändert vor 11 Jahren.]

Hello all ,

I am trying to get The current rendered journal article from its urlTitle
I get the current url then split it to get urlTitle then send it to getArticleByUrlTitle method as following

	ThemeDisplay themeDisplayObject = (ThemeDisplay) request
			.getAttribute(WebKeys.THEME_DISPLAY);
	//long groupId = ParamUtil.getLong(request, "groupId", scopeGroupId);
	long groupId = themeDisplayObject.getScopeGroupId();
	
	String url = PortalUtil.getCurrentURL(request);
	String [] urlString = url.split("/");
	String urlTitle = urlString[urlString.length - 1];
	
//	String articleId = "31575";
	JournalArticle journal = JournalArticleLocalServiceUtil.getArticleByUrlTitle(groupId, urlTitle);

This throws the following exception

Hi,
after splitting you need to decode it to the normal form use HttpUtil.decode(urlTitle) .
