DataTable works with DataModels...and DataModels only supports: * java.util.List * Array of java.util.Object * java.sql.ResultSet (which therefore also supports javax.sql.RowSet) * javax.servlet.jsp.jstl.sql.Result * Any other Java object is wrapped by a DataModel instance with a single row. (The above objects are implicitly used to build a DataModel) As per JSF Specification. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4033412#...
