Accessing one of multiple configuration points

[Martin Pike]

I am attempting to initialise an instance of a class with one of two sets of data, specified in a hivemodule.xml file, defined as contributions attached to configuration points. The code shows instantiating of the object. If the service point called is 'testConfig.address' the code runs ok, but if I call the service point 'testConfig.address2' which references the second contribution it fails with error: Error at file:...../META-INF/hivemodule.xml, line 41, column 72: Unable to update property data of object [EMAIL PROTECTED]: java.lang.reflect.InvocationTargetException org.apache.hivemind.ApplicationRuntimeException: Unable to update property data of object [EMAIL PROTECTED]: java.lang.reflect.InvocationTargetException I am new to HiveMind and would appreciate any pointers as to what I'm doing wrong. --Code    public static void main(String[] args) {        Registry registry = RegistryBuilder.constructDefaultRegistry();        Address address = (Address)registry.getService("testConfig.address2", Address.class);        System.out.print(address.getAddress());    } -- hivemodule.xml <?xml version="1.0"?> <module id="testConfig" version="1.0.0" package = "test.config">    <configuration-point id="Address">      <schema>        <element name="datum">          <attribute name="key" required="true"/>            <attribute name="value" required="true"/>          <conversion class="test.config.Datum"/>        </element>      </schema>    </configuration-point>    <configuration-point id="Address2" schema-id="Address" />      <contribution configuration-id="Address">      <datum key="road"     value="Temple Quay"/>      <datum key="town"     value="Bristol"/>      <datum key="postcode" value="BS1"/>      <datum key="country"     value="UK"/>    </contribution>    <contribution configuration-id="Address2" >      <datum key="road"     value="Pall Mall"/>      <datum key="town"     value="London"/>      <datum key="postcode" value="SW1"/>      <datum key="country"     value="UK"/>    </contribution>  <service-point id="address" interface="test.config.Address">    <invoke-factory>      <construct class="test.config.AddressImpl">          <set-configuration property="data" configuration-id="Address"/>      </construct>    </invoke-factory>  </service-point> <service-point id="address2" interface="test.config.Address">    <invoke-factory>      <construct class="test.config.AddressImpl">          <set-configuration property="data" configuration-id="Address2"/>      </construct>    </invoke-factory>  </service-point> </module> Regards Martin Pike
