> (1) I've gained some insight into the issue. It seams there are a default set of policies as well as some other classes that are loaded when I Do SCADomain scaDomain = SCADomain.newInstance("helloworld.composite");. They are:
> org.apache.tuscany.sca.policy.security.SecurityPolicyDefinitionsProvider
> org.apache.tuscany.sca.binding.ws.axis2.WSBindingDefinitionsProvider
> org.apache.tuscany.sca.binding.sca.SCABindingDefinitionsProvider
> org.apache.tuscany.sca.policy.logging.LoggingPolicyDefinitionsProvider
> This is done in the class org.apache.tuscany.sca.definitions.imp.DefaultSCADefinitionsProviderExtensionPoint and the method loadProviders. My composite file is as follows:
> <?xml version="1.0" encoding="UTF-8"?>
> <composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
> targetNamespace="http://helloworld"
> xmlns:hw="http://helloworld.gdit.com."
> xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0"
> name="helloworld">
> <component name="HelloWorldServiceComponent">
> <implementation.java class="helloworld.HelloWorldImpl">
> <operation name="sayWorld" requires="tuscany:logging"/>
> </implementation.java>
> <service name="HelloWorld">
> <interface.java interface="helloworld.HelloWorld"></interface.java>
> <binding.ws/>
> </service>
> <reference name="helloService" target="HelloComponent" />
> <reference name="worldService" target="WorldComponent" />
> </component>
> <component name="HelloComponent">
> <implementation.java class="helloworld.HelloServiceImpl"/>
> </component>
> <component name="WorldComponent">
> <implementation.java class="helloworld.WorldServiceImpl">
> </implementation.java>
> </component>
> </composite>
> (2)The Composite file specifies thet <operations name="sayWorld" requires="tuscany.logging"> which specifies that it the method sayWorld needs to be logged. I have a definitions file associated with my test programs which specifies the policy:
> <?xml version="1.0" encoding="UTF-8"?>
> <definitions xmlns="http://www.osoa.org/xmlns/sca/1.0"
> targetNamespace="http://tuscany.apache.org/xmlns/sca/1.0"
> xmlns:sca="http://www.osoa.org/xmlns/sca/1.0"
> xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0"
> xmlns:helloWorld="http://HelloWorld">
> <!-- PolicySets -->
> <policySet name="JDKLoggingPolicy" provides="tuscany:logging" appliesTo="sca:implementation.java"
> xmlns="http://www.osoa.org/xmlns/sca/1.0">
> <!--tuscany:jdkLogger name="HelloWorld">
> <logLevel>FINER</logLevel>
> </tuscany:jdkLogger-->
> </policySet>
> </definitions
> (3)My Understanding (and it may be wrong) is that the requires in the composite file is supposed to map to <policySet name="JDKLoggingPolicy" provides="tuscany:logging" appliesTo="sca:implementation.java" xmlns="http://www.osoa.org/xmlns/sca/1.0"> line in the definitions.xml file and somehow this is supposed to map to the implementation of the logger. This apparently is not the case. I ran my test program without the definitions.xml file associated with it and it still runs without error. What I found is that the <operation name="sayWorld" requires="tuscany:logging"/> maps to the intent for the logger which is in the definitions.xml file in the logger package. The file is as follows:
> <?xml version="1.0" encoding="ASCII"?>
> <definitions xmlns="http://www.osoa.org/xmlns/sca/1.0"
> targetNamespace="http://tuscany.apache.org/xmlns/sca/1.0"
> xmlns:sca="http://www.osoa.org/xmlns/sca/1.0"
> xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0">
> <!-- Policy Intents Defined by the SCA Runtime -->
> <intent name="logging"
> constrains="sca:implementation.java">
> <description>
> All messages to and from this implementation must be logged
> </description>
> </intent>
> </definitions>
> If I change the intent name="logging" to something I then get the Policy violation error. So this leads me to the following questions and possible issues:
> 1. Where does the list of polices that are being loaded as described in (1) above come from?
> 2. Is there a way for me to add my policy to this list or somehow get it resolved to my intent so that I can define my own policies?
> 3. Is the policy set the method of mapping a policy to an intent?
> 4. Is the definitions file associated with the composite app even used?
> I have my own driver and will uploaded it to the jira when the SCA Policy component is created.
