EngineConfigurationFactoryFinder.requiredMethod should include package names.

The EngineConfigurationFactoryFinder.requiredMethod documents the signature of the factory method that custom factories must implement. The return type should be fully qualified to avoid any confusion.

I just spent a couple of hours debugging why it couldn't find my factory method - it was because it returned the implementation type, not the interface type.

Simply change line 59 of EngineConfigurationFactoryFinder to:

private static final String requiredMethod =
"public static org.apache.axis.EngineConfigurationFactory newFactory(Object)";
