[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-2219) Introduce way to retrieve proxy object of a Seam JavaBean Component
[ http://jira.jboss.com/jira/browse/JBSEAM-2219?page=all ]
Wolfgang Schwendt updated JBSEAM-2219:
--------------------------------------
Description:
The EJB programming model requires that a Session Bean never passes a
"this"-pointer to other client objects. Instead,
javax.ejb.SessionContext provides a method getBusinessObject(). If a SessionBean wants
to pass a reference pointing to itself to other clients, it first has to retrieve its own
EJB object reference by calling SessionContext.getBusinessObject() which it then can pass
to other beans. This reference returned by
javax.ejb.SessionContext.getBusinessObject()
is the equivalent to Java's this pointer.
With respect to Seam's interceptor framework, such a feature is missing as far normal
JavaBean components are concerned. It leads to subtile programming errors:
Consider
