问题 Does the JSR 286 spec require the presence of a web.xml file in WARs containing portlets? At first, I thought so but then I created a portlet without a web.xml , deployed it in Liferay and it worked flawlessly. So is it an extension (or a bug) of Liferay, or is it not necessary to have such a file? 回答1: As Olaf rightly said portlet is nothing but a web application.

Any help would be welcome. 回答1: Unfortunately the Swing Application Framework was deprecated and removed. It never became a
