Re: Java: Entity Beans not synchronising with database

[Duncan Alexander]

Hi David,             Are you using EJB 1.1 or EJB2.0, home methods don’t exist in EJB1.1.               If its EJB2.0 then…You say on the one hand that you are using an entity ‘home’ method to retrieve the data that has just been entered in the previous transaction, but on the other hand you say that the entity bean you ‘created’ does not reflect the data in the DB. Calling an entity home method does not imply the creation of an entity bean only the temporary use of a bean from the free pool. If your home method is only accessing the variables of the entity you cannot depend on the synchronisation with the DB which happens when creating and accessing a bean directly.   >9.5.4 home methods >An entity bean’s remote home interface may define one or more home methods. Home methods are >methods that the bean provider supplies for business logic that is not specific to an entity bean instance.     regards   DGA   -----Original Message----- From: A mailing list for Enterprise JavaBeans development [mailto:[EMAIL PROTECTED]] On Behalf Of Kumar, David Sent: 09 April 2002 09:37 To: [EMAIL PROTECTED] Subject: [EJB-INT] Java: Entity Beans not synchronising with database   We are currently using a stateless session bean to perform a direct update of a table in the database and then using the home method of an entity bean which is mapped over the same table to retrieve the records that have just been updated. Because both transactions are managed by the application server, it should know that the entity bean needs to refresh from the database because some data has changed.   However the result is that the direct update is committing the change to the database as you would expect, but the entity bean does not reflect that change when it is created. Do we need to force the entity bean to refresh from the database?   We are using 1.5.4 Orion Application Server, EJB 1.1 and MSSQL 7 database.   ta,   - dave
