[Raymond Feng <rfeng@us.ibm.com>]

Thank you for the response. I agree
with you that we should add some text to prevent the annotations being
misused on arbitrary business methods which don't follow the JavaBeans
setter pattern.

Thanks,
Raymond

Hi Raymond,
 
 I was just being asked what does it mean to have it on arbitrary
business method 

Maybe as part of issue resolution we can add the constructor usage in
the text,  as well as say  the runtime must not support those
on
arbitrary business methods operations that are different from
constructors.
 
Best Regards
Peter

Hi, 

I don't think we can remove the PARAMETER target for the
@Reference/@Property annotations. The constructor based injection will
require that. The following is a sample  service impl: 

@Service(MyService.class) 

public class MyServiceImpl { 

        public MyService(@Reference AnotherService
ref, @Property prop)
{ 
            } 
... 
} 

Thanks, 
Raymond

 [sca-j] NEW ISSUE annotations on parameters

________________________________




TARGET: Java Common Annotations and APIs Specification Version 1.1 (WD
26 September 2007)

DESCRIPTION:
The current Reference and Property annotation are defined in sections
8.13 and 8.14  as : 

@Target({METHOD, FIELD, PARAMETER})
@Retention(RUNTIME)
public @interface  Reference {


@Target({METHOD, FIELD, PARAMETER})
@Retention(RUNTIME)
public @interface  Property {


I.e. there is a possibility to define those annotations on parameter.
However the text description doesn't allow that feature and mentions
only field \ setter method injection : 

"The @Property annotation type is used to annotate a Java class field
or
a setter method that is used to inject an SCA property value. "

"The @Reference annotation type is used to annotate a Java class field
or a setter method that is used to inject a service that resolves the
reference."

PROPOSAL:
Drop the possibility of defining those annotations on parameters.
