[Vishnu Mohan, modificado 9 Anos atrás.]

Hi,
I am using Liferay 6.2 ce-ga2 ,tomcat 7.0.42 and i integrated vaadin 7.1.15 with the liferay using vaadin dependency jars, vaadin control panel etc... But when deploying portlet application in tomcat deploy folder, the deployment is not performing and it results in some exceptions.

SEVERE: Exception sending context initialized event to listener instance of class com.liferay.portal.spring.context.PortalContextLoaderListener
java.lang.RuntimeException: java.lang.RuntimeException: Exception in org.eclipse.osgi.framework.internal.core.SystemBundleActivator.start() of bundle org.eclipse.osgi.

Does your vaadin portlet leverage OSGi?

What does this means?? I dont know about that.
When starting the tomcat server, It is also showing like this.

"Queueing your-portlet for deploy because it is missing marketplace-portlet".

"Group or layout set prototype already exists for company liferay.com".
