I am creating a Vaadin (version 7) portlet, my development environment is eclipse 4.3.1 + tomcat-7.0.27+Liferay-portal-6.1.1-ce-ga2, I am checking the stuff on tomcat and the portlet runs fine there.
Now my deployment environment is Glassfish-3.1.2+Liferay-portal-6.1.1-ce-ga2, the same portlet and the log message is: “sampleApp was successfully deployed”, the Portlet error is “Failed to load the bootstrap javascript: ./…/…/VAADIN/vaadinBootstrap.js”.
Please help me solve this.
