Subject Re: how to get config info from portlet.xml in struts2 action
Date Fri, 09 Jan 2009 06:41:07 GMT
servlet-config is used for getting parameter, session objects, etc.

however I found the solution for my case, no need to use
PortletContextAware interface, just use
PortletActionContext.getPortletConfig() to get the PortletConfig
object, then retrieve the info from this object is ok.
