I implemented a Liferay 7.2 portletmvc4spring module, I followed this tutorial https://github.com/liferay/portletmvc4spring/blob/master/README.md but I have a problem when deploying this portlet to Lr7.2 instance ( i searched in google but I didn't found a concrete solution ) maybe some one had the same issue in the past and could help maybe...
The problem is the following :
2020-01-06 20:36:43.468 ERROR [fileinstall-/usr/share/portail/liferay-portal-7.2.0-ga1/osgi/war][WebXMLDefinitionLoader:1130] baseLr7Portlet_1.0.0 [1148] una java.lang.ClassCastException: class com.liferay.portletmvc4spring.ViewRendererServlet
java.lang.ClassCastException: com.liferay.portletmvc4spring.DispatcherPortlet cannot be cast to javax.portlet.Portlet
The full trace is the following :
