Hi, Refer to the appropriate guide from this link. http://www.jboss.org/jbossportal/docs/ As far as JSR 168 spec is concerned Inter portlet communication is not standardized. Jboss supports this through listeners.You need to implement your own listeners and the guide has instructions. Also you will find, in the guide, when partial refresh works and when it does not.
