{bgcolor:#C3CDA1}What does the promote keyword in the composite file mean? 
{bgcolor} 

An

SCA

composite

can

be

used

as

an

implementation

(implementation.composite)

for

a

component.

This

is

so-called

recursive

composition.

It

allows

pre-assembled

composites

to

be

reused.

"promote"

can

be

used

to

make

services

or

references

declared

on

a

component

inside

the

composite

visible

for

wiring

at

the

composite

level.

The

composite

services

and

references

can

be

then

further

configured

when

it's

used

as

a

component

implementation

at

outer

level.

Hope

the

following

samples

help.

 

{code} 
<composite name="Composite1" xmlns:ns="http://dummy"> 
<component name="C1"> 
<implementation.composite name="ns:Composite2"> 
<!-- wire ref1 to component C3's service1 --> 
<reference name="ref1" target="C3/service1"/> 
<!-- configure the service with ws binding --> 
<service name="svc1"> 
<binding.ws .../> 
</service> 
</component> 
</composite> 

{code} 

{code} 
<composite name="Composite2" targetNamespace="http://dummy" 
xmlns:ns="http://dummy"> 
<component name="C2"> 
<implementation.java class="my.C2Impl"> 
</component> 

<!-- innerService of component C2 is promoted as svc1 --> 
<service name="svc1" promote="C2/innerService"/> 
<!-- innerReference of component C2 is promoted as ref1 --> 
<reference name="ref1" promote="C2/innerReference"/> 
</composite>
