I need to implement velocity templates. Can somebody direct me as to how I can go about doing this? I read in the forum that this would be supported in the 2.1 release of Alfresco. Is there any document available that I can refer to?
Velocity is not supported in 2.1, Freemarker templates are, they are quite similar to Velocity.
Implementing Velicity will involve implementing org.alfresco.web.forms.RenderingEngine interface. See org.alfresco.web.forms.FreeMarkerRenderingEngine for example.
