Haleh,
At the moment <implementation.osgi/> looks like this:
<tuscany:implementation.osgi
bundle="supplychain.Customer"
bundleLocation="file:target/factory/Customer.jar"
scope="STATELESS"
allowsPassByReference="supplychain.OSGiCustomerImpl" />
The bundle location is in <implementation.osgi/> temporarily and will
eventually come from the contribution. The other attributes correspond to
equivalent annotations in SCA Java implementation (@Scope and
@AllowsPassByReference in the example).
OSGi bundles are not introspected by implementation.osgi. Interfaces exposed
through SCA services have to be provided outside the bundle since Tuscany
needs to read them (and because they can be potentially used by non-OSGi
implementation types in SCA). Hence annotations from interfaces are
processed - so @Remotable is processed as an annotation and does not have an
equivalent <implementation.osgi/> attribute.
Since the <implementation.osgi/> attributes are non-standard and
inconsistent with Java, we would like to remove these and instead introduce
annotation support for OSGi implementation classes (@Scope and
@AllowsPassByReference will be processed from the implementation classes
contained in the OSGi bundle). With this change, we would also be able to
support property injection through the use of @Property annotations, which
is not currently supported.
Thank you...
Regards,
Rajini
