Mail portlet error

When i add the mail-portlet to Liferay Enterprise 5.2 version, i hit the error:

Exception sending context initialized event to listener instance of class com.liferay.mail.servlet.MailServletContextListener

java.lang.NoSuchMethod: com.liferay.portal.kernel.messaging.Destination.register(com/liferay/portal/kernel/messaging/MessageListener)

Hi Evelyn.

I can recomend you to install Liferay 6.05. It’s much easier to install than the version you already have, and also the vaadin mail portlet is included, no need to install it.

I hope this help :slight_smile:
