Hi
If you
want to use Entity Beans, you need to store your state in a database with CMP,
or write your own persistancemechanism with BMP. That way it does not
matter that new beans are created.

Emne: [jdjlist] EJBs as a Remote object Cache ServerHi:We are trying to develop a remote cache server. Our goals is to reduce memory consumption (and GC cycles) in our app server and share the common read-only data across multiple servers. .We have experimented with RMI and EJB-based solutions. The RMI solution seems to work. However, we are running into trouble with the EJB solution. We are using Websphere 4.0. for the EJB-based approachFirst we tried to use a stateful session bean, but soon we discovered that it would only work for a given client, not as a general purpose cache. Now we are trying to use entity beans, but the container does not give us the same bean instance. It creates a new bean instance which defeats the purpose of using the bean as a cache server. We are passing the reference to the bean between different clients using the EJBHandle serialized in LDAP (not calling EJBCreate or EJBFind).Do we have a chance of making the EJB solution work, or should we drop this approach and stay with the RMI solution?Thanks in advance for the help.Kamyar
