Isn't this a component whose implementation is a DAS query (not DAS
itself)? The component offers a service which is defined as
DASService. So, instead of Java code, we are using a query.
I say this because in SCA we don't really have the notion of an
"implementation-less" service and a component is defined by the SCDL
<component> entry so there is always a component.

As for the naming :) I was just calling DAS exposed as an SCA
service...

The term DAS-POJO Service is probably confusing. What I meant is
service implemented in Java that does not require a new component

POJService?

Yes, this was THE thing I know we need to improve as mentioned on this
thread :
http://www.mail-archive.com/tuscany-dev%40ws.apache.org/msg10421.html
SCA guys, any suggestions about something already available in
SCA ? Or
maybe an Annotation ?

Could you elaborate little bit more here ? Why exactly this ?
Could the Vector argument list be replaced with a List?

Sure, it was just a setting in my eclipse IDE, I'll create a patch
removing
that.
As for the other things... I'll look into that and provide a patch
with the
changes...
