IBM Websphere Portal V5: A Guide for Portlet Application Development

Simple portlet actions are not available in the Portlet API prior to V4.2. To check if a simple action String is supported, you can use getMajorVersion() and getMinorVersion() methods of the PortletContext, which return, respectively, the major and minor version of the Portlet API that the portlet container supports. The sample code is shown in Example 5-6.

Example 5-6. Check PortletAPI version

if ( (getPortletConfig().getContext().getMajorVersion() <= 1) && (getPortletConfig().getContext().getMinorVersion() <= 1) ) { // simple actions not supported } else { // simmple actions supported }
