Vaadin uses resources to serve up static content. For example, there's the ClasspathResource which will stream a resource from an image in the classpath.

But in the end it's a simple interface that you need to support to create an input stream from your object. So you'd fetch the object from the doc library, wrap the object w/ the interface (I think it's a StreamResource interface) and feed the stream back to the Vaadin component.

This information helpul to me,
I add my image file in src folder of liferay plugin portlet and use it as below

verticalLayout2.addComponent(new Embedded("", new ClassResource(
"/chart.png", this)));

Make sure to use "/" as first character of path of image

"/" as the first character is the norm for a classpath-based resource, it is not specific to Vaadin.
