[jira] Created: (TUSCANY-3247) Cannot get WidgetImplementationFactory (NoSuchMethodException)

Cannot get WidgetImplementationFactory (NoSuchMethodException)
--------------------------------------------------------------

                 Key: TUSCANY-3247
                 URL: https://issues.apache.org/jira/browse/TUSCANY-3247
             Project: Tuscany
          Issue Type: Bug
          Components: Java SCA Widget
    Affects Versions: Java-SCA-1.5
            Reporter: Andrew Mak


The following exception is thrown when trying to get a WidgetImplementationFactory from the ModelFactoryExtensionPoint:

Caused by: java.lang.NoSuchMethodException: org.apache.tuscany.sca.implementation.widget.WidgetImplementationFactory.newInstance()
	at java.lang.Class.throwNoSuchMethodException(Class.java:283)
	at java.lang.Class.getMethod(Class.java:825)
	at org.apache.tuscany.sca.extensibility.ServiceDiscovery.newFactoryClassInstance(ServiceDiscovery.java:165)
	at org.apache.tuscany.sca.contribution.DefaultModelFactoryExtensionPoint.getFactory(DefaultModelFactoryExtensionPoint.java:118)

I tried newing a WidgetImplementationFactory myself and then adding it the ModelFactoryExtensionPoint.  However, the factory does not appear to get cached (seems to be due to the fact that WidgetImplementationFactory does not implement any interface and extends directly from Object)

Luciano Resende resolved TUSCANY-3247.
--------------------------------------

       Resolution: Fixed
    Fix Version/s: Java-SCA-Next
                   Java-SCA-1.5.1

Fixed and verified it's working by instantiating the factory via extension point mechanism.
