Hello All!
Im facing problems trying to Stream/download files through portlet. I also
used DynamicWebResource and a Resource link to serve the Resource Data. On a
simple Wicket application everything works fine, but when my war is deployed
as a portlet into a Liferay 5 instance, it doesnt work.
The browser response is : " The requested resource
(/wick-portlet-0.0.1-SNAPSHOT/wick-portlet/) is not available".
Does anyone have some idea,or know any issue about this kind of feature?
thanks!
