I display articles in a Web Content Display portlet (Liferay).
The question is :
How can I read that portlet URL parameters from another portlet?
Thanks.
You can use JSR-268 standard Inter Portlet Communication client or server side.
See liferay wiki: http://www.liferay.com/community/wiki/-/wiki/Main/Inter-portlet+communication And for shared render parameters and event communication: http://www.liferay.com/community/wiki/-/wiki/Main/Eventing+and+Shared+Render+Parameters
Hope this helps, regards
