I downloaded and installed Red Hat JBoss Portal - Version 6.2.0.GA, then I created a new portal. Now, I would like to customize it completely, including changing the logo, etc. Going in Sites->Manage Sites->Edit layouts, I can edit or delete portlets. But I would like to customize the banner portlet, for example, such that to display a different logo. How can I do that without having to unzip WARs and to chase CSS files, etc ?
