[Yang Lei <yanglei@us.ibm.com>]

Here is the latest Issue 27 proposal integrated with Vamsi and Mike's comments, except the pending discussion on if we need to map the annotations to componentType.

Thank you .

I thought we removed <operation/> from the SCDL, but it's still there in the assembly spec. Assembly 30 says it was applied, so why is it still there?

On point two, since there is no way to reflect an annotation on a method in the CT (because there's no method element in the CT), are you suggesting that somehow the interface is modified? I don't understand how that works, esp. if the interface is an artifact that was provided by the developer.

I don't think it's true that annotations MUST show up in the CT. The Java C&I is perfectly within its rights to describe how these annotations are to be handled by the SCA Java runtime. It's certainly preferrable if these things were to be present, but I don't see it as required, and given that it's impossible to do so, we're stuck.

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>

Thanks Dave for the review and comments earlier.
