Stuart Douglas updated WELD-921:
--------------------------------
Attachment: chat-log.txt
I discussed this wish Ales and we decided that this was to big a change for a point
release.
For now it can be worked around by having SessionObjectReference guess at the
correct business interface to use, based on the interface type that is passed in,
for the majority of situations this should not cause any problems.
Incorrect handling of business interfaces for EJBs (where defining
class of business method is not the Business interface of the EJBs)
---------------------------------------------------------------------------------------------------------------------------------------
Key: WELD-921
URL:
https://issues.jboss.org/browse/WELD-921
Project: Weld
Issue Type: Bug
Components: Weld SPI
Affects Versions: 1.1.0.Final, 1.1.1.Final
Reporter: Sivakumar Thyagarajan
Fix For: 1.1.2.Final
Attachments: chat-log.txt
This is based on the scenario described in
http://java.net/jira/browse/GLASSFISH-16186
- @Named @Stateless TimeProviderImpl extends SimpleTimeProvider implements
LocalTimeProvider.
- SimpleTimeProvider implements TimeProvider (the latter defining some methods, the
former implementing them. No annotations.)
- LocalTimeProvider is @Local and also extends TimeProvider and does nothing more.
So the Local Business interface is LocalTimeProvider.
The following injection is performed on a SessionScoped Bean
@Inject
private LocalTimeProvider timeProvider1;
The Weld bean proxy for the SessionBean Object reference being injected(timeProvider1)
tries to get [1] the BusinessObject when a method is invoked on it. Weld seems to use [2]
the declaring class of the method being invoked to determine the business interface.
Though the business interface of the Bean is set to com.dummy.time.LocalTimeProvider, the
class that declares the method being invoked ("getThisMonth()") is
com.dummy.time.TimeProvider.
Therefore, the Weld implementation calls
SessionObjectReferenceImpl.getBusinessObject("com.dummy.time.TimeProvider"),
which fails, as TimeProvider is not a Business interface. As per [3], the
businessInterfaceType must be a type of the business interface of the bean. Is Weld
incorrect in mapping the method to its declaring interface. Weld must instead use the
injected type as the business interface, while trying to get the business object.
