RE: [stp-dev] Component Java Projects versus Composite Projects

["Mark Walker" <mwalker@xxxxxxxxxxxxxxxxxxxx>]

Hi Johnson,

I'm concerned a little about your use of the term "big picture".

Given that SCA composites can be infinitely nested (theoretically,
anyway). What about those SCA composites that are internal to other
composites (i.e. being used as component implementations)? So what do we
do about these "middle-sized picture" ;-) composites?

Even more concerning might be the issue of where do we locate composite
service interfaces that have be redefined within the composite (as per
the SCA 1.0 spec, pp. 34-35)?

Please note, I am not advocating that we do have a combination SCA
component and composite project -- I can a logical division --, rather I
am concerned with how we deal with these "edge/corner" cases.

Hi Mark

Yes, we will have a separate composite project.

The current SCA Java component project wizard is used to create a
standard 
service component following SCA java spec.
It is just like the jax-ws project wizard, which is used to create a
jax-ws 
service component.

>From my understanding, we will have a soa network project type 
>(Composite
projects), which is mainly a SCDL assembly editor.
It will allow user to connect multiple components by adding wire/links
to 
setup the big picture of the SOA infrastructure.
Each component in the the assembly editor may come from stp service 
component project within workspace (sca java or jax-ws), external sca 
component, or it maybe a bpel component...etc


Regards

Johnson

Hi All,

Is STP going to have a separate composite project type for containing
SCDL? Or is everything going to be part of the main SCA Java Component
Project? If, so how do we handle SCDL only projects (they just reference
components available elswhere), and Java only (i.e. annotation only)
component projects?

Further to the above: what will be our output archive format for
contributions, the SCA 1.0 spec mentions all kinds of output format?
