implementing lightweight lookup

[chris70]

Hi,

I want to discuss some options for implementing lookups for simple objects (mostly name-value pairs). I dont think there should be an Entity Bean for simple list of values (productTypes, accountTypes, countries etc). If we make these Entity Beans we have to have lots of relationships (CMR) in a CMP 2.0 model.

I am thinking about going with MBeans and expose operations to do CRUD on these lists for site-administrator. EJBs can use these MBeans and do a lookup (or even get a java.util.List). These lists doens't have to be in the DB (normally <50 values) and can be stored in properites file as this data is mostly static.

Any suggestions, comments?

Seems like a lot of work. Are you sure you need this?

I did this using a frontal cache : I update this cache each time there is an CUD action on the entity bean, all client queries are performed on the HasMap of the cache.
