{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>
{code}
