All Implemented Interfaces:

CacheListener, Container, ReadOnlyBeanRefreshEventHandler, JavaEEContainer, EjbContainerFacade

public class ReadOnlyBeanContainer
extends EntityContainer
implements ReadOnlyBeanRefreshEventHandler

The Container that manages instances of ReadOnly Beans. This container blocks all calls to ejbStore() and selectively performs ejbLoad()

public void preInvoke(EjbInvocation inv)

Description copied from class: BaseContainer

Called from EJBObject/EJBHome before invoking on EJB. Set the EJB instance in the EjbInvocation. It must be ensured that the following general pattern is followed by various parts of the EJBContainer code: try { container.preInvoke(inv); returnValue = container.intercept(inv); } catch (Exception1 e1) { ... } catch (Exception2 e2) { ... } finally { container.postInvoke(); }

Specified by:

Description copied from class: EntityContainer

Convert a collection of primary keys to a collection of EJBObjects. (special case: single primary key). Note: the order of input & output collections must be maintained. Null values are preserved in both the single primary key return and collection-valued return cases.
