異常嵌入在一個自定義的Liferay門戶網站內容時

Question

我嵌入網頁內容到部署到Liferay EE 6.1 GA 1自定義portlet使用：

<liferay-ui:journal-article articleId="REMEMBER" groupId="<%=portletGroupId%>" /> 

此錯誤開始出現在日誌和網頁內容是不存在：

有關如何解決此問題的任何想法？

Answer 1

有一件事似乎有所幫助。更新了WEB-INF/liferay-plugin-package.properties包含線路：

portal.dependency.jars=commons-logging.jar,commons-fileupload.jar

從https://www.liferay.com/community/wiki/-/wiki/Main/Liferay+Developer+Cookbook：

如果有任何jar文件中已經存在的門戶網站\ WEB -INF \ lib，你也想在你的插件中使用它們。 請勿重新包裝這些罐子，只需在 docroot\WEB-INF\liferay-plugin-package.properties中添加參考。

Answer 2

請參閱以下網址： http://www.liferay.com/community/wiki/-/wiki/Main/Liferay+UI+Taglib

軸頸文章參數：

articleId = uniqueID of content article 
groupId = group of user 
showTitle = show title of article true or false 
templateId = which of the defined templates for this journal article to use. Note that there is a bug (reported here) in liferay versions before 6.0.2 where templateId is ignored. 

例如： <的Liferay的UI：軸頸文章條款ArticleID = 「22745」 的groupId =」 <％= scopeGroupId％>「/>

Answer 3

Smith， 我創建了cust om portlet並在jsp下面添加了一個web內容，代碼如下，plugin-package.properties中我添加了所有用於JSP頁面的tld文件，並且沒有在屬性文件中添加任何jar文件。

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %> 
<%@ taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme" %> 
<%@ taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %> 
<portlet:defineObjects /> 
<liferay-theme:defineObjects/> 

<liferay-ui:journal-article articleId="11414" articleResourcePrimKey="11416" groupId="<%=themeDisplay.getScopeGroupId() %>" languageId="<%=themeDisplay.getLanguageId() %>" showAvailableLocales="<%=true %>" ></liferay-ui:journal-article> 

我已經使用了最新版本的Liferay 6.1.1 EE GA2的，但我已經驗證它在LR6.1 EE GA1它也工作正常那邊。
