Simon,
The service that the reference is wired to is not in the same JVM. At the
moment, the component definition looks like this:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://osgidistribution";
name="helloworldreference">
<component name="HelloWorldServiceComponent">
<implementation.java class="helloworld.DummyImpl" />
<reference name="helloWorldService">
<interface.java interface="
helloworld.HelloWorldService" />
<binding.ws wsdlElement="
http://helloworld#wsdl.port(HelloWorldService/HelloWorldSoapPort)"/<http://helloworld/#wsdl.port(HelloWorldService/HelloWorldSoapPort)"/>
>
</reference>
</component>
</composite>
I would like to get hold of the proxy corresponding to the reference and add
it to the OSGi registry so that an OSGi bundle which has no knowledge of SCA
can lookup the proxy in its OSGi registry and invoke the service through
this proxy. The OSGi bundle which wants to use this reference is not running
in an SCA runtime. It is running in an OSGi runtime and uses its normal OSGi
registry lookup (with no remote service support) to resolve its references.
We would like to use Tuscany to parse the metadata corresponding to the
reference element above and create a proxy for the remote service which is
then registered with the OSGi registry.
Which code in Tuscany should I look at to create a reference on the fly?
Thank you...
Regards,
Rajini
