Re: [sca-j] NEW ISSUE annotations on parameters

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

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

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.
