Subject:
[sca-j] ISSUE 27 - Security Annotations
in generated Component Type - proposal

Here is the proposal for issue 27: http://www.osoa.org/jira/browse/JAVA-27.

The highlights of the proposal:

1. Instead of defining SCA security implementation policy annotations,
point to JSR 250 security annotations

<mje>

I'm OK with this proposal.

I think that there is a
need to spell out the mapping of the annotations to the intents declared
by the

Policy spec.  It may
seem obvious, but to be normative, you have to state it explicitly.

This should be in 10.6.2
I think.

</mje>

2. Not generating componentTypes for the above annotations, due to two
major reasons: 

some of the annotations can apply onto the methods level,
while component type definition does not have operational level any more.

if we did generate the information into component type,
we also need to generate the policysets to apply the policy...<mje>

I don't agree with this.
 If they dont turn up in the componentType, then in effect they are
useless - or else you are proposing

a second mechanism for
transmitting information from the implementation to the using <component/>

Any annotations on method
or class level MUST turn up in the component type.

Annotations below the method
level MUST be placed on the interface class.  The annotations then
turn up in the componentType

as part of the interface
declaration in the componentType.

I think that this approach
works...

</mje>

3. Also added are the other annotations that is missing from section 8,
related to 10.3 Application intent annotations: 

@Authentication

@Confidentiality

@Integrity

@Intent

@PolicySets

@Qualifier

@Requires

All the changes are under 8.2, 8.5, 8.15, 8.19, 8.22, 8.25, 10.6.2, 10.6.2.1.

<mje>excellent</mje>
