Have you looked into itest/contribution-import-export or
tutorial/store/assets ? It has couple examples related to what you are
doing.

One thing I didn't see in your e-mail is how you are using
sca-contribution.xml, that is the file that would tell the Tuscany
runtime to use a different contribution when resolving dependencies
(based on import/export from sca-contribution.xml)




 Thanks

 Hi,

 The wire element has some errors:

  wire  source=”HelloComponent/Store
            Target=/StoreServiceComponent /StoreService/

 should be:

  wire  source=”HelloComponent/Store
           target=StoreServiceComponent /StoreService/


Good catch Raymond... but also no space on the target, right ?

 should be:

  wire  source=”HelloComponent/Store
   target=StoreServiceComponent/StoreService/



 Thanks,
 Raymond

 Subject: Use EmbeddedScaDomain to deploy multiple contributions


 I tried to use Tuscany EmbeddedScaDomain to deploy multiple contributions
 which can share some common resources. Here are my contributions:

 Contribution A (http://inner) contains InnerComposite, looks like:

 composite xmlns=http://www.osoa.org/xmlns/sca/1.0;
 targetNamespace=http://inner;
  name=InnerComposite
  component name=StoreServiceComponent
       implementation.java class=store.StoreServiceImpl/
       service name=StroreService
                       binding.sca uri=/StoreServiceComponent
 /StoreService/
      /service
  /component
 /composite

 Contribution B(http://outer) contains OuterComposite, looks like:

 composite xmlns=http://www.osoa.org/xmlns/sca/1.0;
   targetNamespace=http://hello;  xmlns:inner=http://inner;
   name=OuterComposite

  !--
    include name=inner:InnerComposite/
   --
  component name=HelloComponent
       implementation.java class=hello.HelloImpl/
       reference name=”Store”/
    /component
  wire  source=”HelloComponent/Store
            Target=/StoreServiceComponent /StoreService/
 /composite

 Both composites are declared as deployable. Contribution A is exported to
 namespace http://inner and contribution B imports it.

 The “Store” service is implemented using “COMPOSITE” Scope annotation, which
 is intend to provide a shareable store instance for other contributions such
 like B.

 However, I got a warning message when deploying B after contribution A is
 deployed successfully. The warning message is “Wire target not found :
 HelloComponent/Store”. It looks like the wire in one composite can’t link to
 components belongs to other composites.

 I can make contribution B deployed only by adding the “include” declaration.
 But I am not sure this will meet my requirement because now the Store
 service belongs to two composites.  The instance shouldn’t be shared among
 multiple composites since its scope is “COMPOSITE”.
