Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, ther...

Hey there, I have a JSF 2.0 application running on GlassFish v3. It has EJBs that serve database data via JPA for the main applications sessions. Even on non-IDE app-server, the EJB calls are very slow. Between some pages, the user has to wait over 10 seconds to get to the next page. The EJB runs on the same application server, and onl...
Obviously using stateless EJB beans in an entity bean smells, but please consider a scenario as follows and tell me if you know of a better solution: I have an InvoiceTemplate Entity Bean with field NextInvoiceDate Generating NextInvoiceDate is a complex procedure and should be performed outside of the InvoiceTemplate class NextInvoice...
We would like to migrate an application written using EJB2.1 beans (both Entity and Sessions beans) to EJB3 to improve on maintanance and use new features in the EJB3 spec. How would we do the migration and give the users the guarantee (if any) that the migrated system still works just as the old one. The original app didn't have test c...

I'm using EJB and JSF. I made a jsp simple page with a button "get list". When it's clicked, a managed bean method is called that sets the list, which is then displayed in the jsp with the dataTable tag.
