Subject:
[sca-j] JAVA-17: Proposed resolution

The resolution of JAVA-55 has clarified the rules
for which setter

methods are taken into account when introspecting for properties

and references.  The relevant text is as follows:

  The following setter methods and fields are taken into consideration:

   1. Public setter methods that are not part of the implementation
of

      an SCA service (either explicitly marked with @Service
or implicitly

      defined as described above)

   2. Public or protected fields unless there is a public setter method

      for the same name

Point 1 above makes it clear that the "setX" examples given in
the JIRA

are not properties or references.

The JIRA also raises the following question.

  "Another question would be: Is it valid to have a setter method

   denote both a property/reference and business operation?"

For introspected properties and references, the text in point 1 above

rules out this possibility.  However, the possibility does exist for

properties and references specified by explicit annotations, for example:

  public class MyServiceImpl implements MyService {

      @Property

      public void setX(String x) {

          ...

      }

  }

  @Remotable

  public interface MyService {

      void setX(String x);

  }

I believe this could be useful in some cases and should not be

disallowed.

I therefore propose that this issue should be closed as having been

resolved by JAVA-55.
