Start by adding a custom finder method to your Home interface (e.g. Enumeration findByEmployeeName(name)) Use the EJB extensions editor (pick a CMP and say "open with extensions editor") to open an EJB extensions editor. Click on the type of EJB finder you want (I strongly suggest using a WHERE clause finder) and type in the part of the WHERE clause after the "WHERE" such as "T1.NAME = ?1".
My
workbook goes into a little more detail about the types of custom finders, as does the Help (which I would STRONGLY suggest you read).
