That is no problem at all. I would start by downloading the MyFaces example application from myfaces.apache.org. There are some very good samples there. Basically you will need a backing bean the contains a list of the objects. In the constructor of the backing bean read the customers from a data source and create the object instances.
A jsp page to display the data in the managed bean.
the faces config xml file to define the backing bean, navigation actions to the jsp.
