Lou Amodeo commented on TUSCANY-1000:
-------------------------------------
Hi, I have tried a few permutations of this and it doesn't appear to be
functioning unless I change the @Service and remove the multiple interfaces.
I did notice that I did not correctly specify the componentName/seviceName the
first time. I left off the componentName. However when I add the component
name as specified in the default.scdl I receive an exception. I assume the
componentName will be taken for the
default.scdl and the serviceName's will be derived from the @Service interface
class names resulting in the string specified below?
Here is the client locate()
aConversationsClient =
CurrentCompositeContext.getContext().locateService(ConversationsClient. class,
ConversationsClient/ConversationsClient");
The @Service annotation:
@Service
(interfaces={ConversationsClient.class,ConversationsClient2.class })
The class definition: (note this client component also impliments a callback
interface)
public
class ConversationsClientImpl implements ConversationsClient,
ConversationsClient2, ConversationsCallback {
The default.scdl:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
name="ConversationsTest">
<component name="ConversationsClient">
<implementation.java
class="org.apache.tuscany.sca.test.ConversationsClientImpl"/>
<reference name="aService">
ConversationsService
</reference>
<reference name="anotherService">
AnotherService
</reference>
<reference name="aLifeCycleService">
ConversationLifeCycleService
</reference>
</component>
<component name="ConversationsService">
<implementation.java
class="org.apache.tuscany.sca.test.ConversationsServiceImpl"/>
</component>
<component name="AnotherService">
<implementation.java class="org.apache.tuscany.sca.test.AnotherServiceImpl"/>
</component>
<component name="ConversationLifeCycleService">
<implementation.java
class="org.apache.tuscany.sca.test.ConversationsLifeCycleServiceImpl"/>
</component>
</composite>
The exception:
