[cdi-dev] Inconsistency in the spec regarding remote EJBs

[Tomas Remes]

Hi,

I agree. Shouldn't we specify what happens in opposite case? Or maybe better to update following in "10.4.2. Declaring an observer method" as well:

"If a non-static method of a session bean class has a parameter annotated @Observes, and the method is not a business method of the EJB, the container automatically detects the problem and treats it as a definition error."

Hi guys, 


Bill Shanon, just pointed me to this test in TCK: 

https://github.com/cdi-spec/cdi-tck/blob/1.2/impl/src/main/java/org/jboss/cdi/tck/tests/event/observer/resolve/enterprise/ResolveEnterpriseEventObserverTest.java 

It tests the following assertion: 

"If the bean is a session bean, the observer method must be either a business method of the EJB or a static method of the bean class.” 

The EJB containing the observers for the test is: 

https://github.com/cdi-spec/cdi-tck/blob/1.2/impl/src/main/java/org/jboss/cdi/tck/tests/event/observer/resolve/enterprise/Spitz.java 

The EJB contains one business method coming from a local interface, one from a remote and one static method. the 3 are observers methods 

The test expects that the remote business observer method should be called. 

Here we have an inconsistency IMO. By doing this we are violating rules the CDI spec regarding the fact that remote EJBs are not CDI beans. And we are calling this remote business method passing the event payload by reference and not by value which violates EJB specification regarding remote EJB. 

I suggest that we change the assertion to: 

If the bean is a session bean, the observer method must be either a local business method of the EJB or a static method of the bean class. 

and the TCK accordingly. Any thought ? 

Antoine
