                                                  Object ejbInstance)

Called when we must ask the container to remove a specific

Parameters:

proxyInstance - The contextual reference

ejbInstance - The underlying EJB instance to be removed

getRemoveMethods

public List<Method> getRemoveMethods()

Subclasses can override this.

Returns:

remove methods

getBusinessLocalInterfaces

public List<Class<?>> getBusinessLocalInterfaces()

addDependentSFSB

public void addDependentSFSB(Object dependentSFSB,
                             Object proxy)

Keep track of which proxies have gotten EJB objects out of a context

Parameters:

dependentSFSB - The dependent SFSB acquired from the EJB container

proxy - The OWB proxy instance whose method handler acquired the dependnet SFSB

removeDependentSFSB

public void removeDependentSFSB(Object proxy)

Call after observing an @Remove method on an EJB instance

Parameters:

proxy - the proxy instance the dependent SFSB is associated with

getDependentSFSBForProxy

public Object getDependentSFSBForProxy(Object proxy)

Parameters:

proxy - an instance of our own proxy

Returns:

the underlying EJB instance associated with the proxy

needsBeanLocalViewAddedToTypes

public boolean needsBeanLocalViewAddedToTypes()

Returns:

true if the bean supports a no-interface (bean-class) local view but the container does not return it in the list of business local interfaces.
