Java Concepts

  Some times unknowingly admin  may remove the guest permissions for the login portlet and when we try to access the portlet it says "you do not have permission to view the portlet" . Then we have to retrive back the permisions but portlet is not accessiable  what to do! Here we go , Add the following properties in portal-ext.properties  auto.login.hooks=com.liferay.portal.security.auth.ParameterAutoLogin , Whenever we add parameter in portal-ext.properties we need to resart the server. Access the url as follows  http://localhost:8080/c/portal/login?parameterAutoLoginLogin=yourscreennameOrEmailAddress&parameterAutoLoginPassword=password Retrieve back the permission changes and remove the auto.login.hooks from the portal-ext.properties. Thats it you have done and you will able to see the login portlet
