WO with WebServices - Error in Serialization

Hi all,
I'm trying to produce a WebService that create and return a list of ERXGenericRecord.

The WS works correctly (I can create the Record in the DB passing the parameter I need to create it). But when I call the other action, that return all the objects from an entity, and try to return a NSarray with the Objects fetched from the DB, I get this error:

IOException: No serializer found for class org.apache.log4j.Logger in registry org.apache.axis.encoding.TypeMappingDelegate@1896d2c2

  at org.apache.axis.encoding.SerializationContext.serializeActual(SerializationContext.java:1507)

  at org.apache.axis.encoding.SerializationContext.serialize(SerializationContext.java:980)

  at org.apache.axis.encoding.SerializationContext.outputMultiRefs(SerializationContext.java:1055)

  ... skipped 10 stack elements


I've followed this Guide to prepare the WS: http://wiki.wocommunity.org/display/documentation/Web+Services-Web+Service+Provider

Because, the WS is serializing a complextype I've added also added the Factories for the EO.

WOWebServiceRegistrar.registerFactoriesForClassWithQName( 

                new BeanSerializerFactory(TestPicture.class, new QName("http://ws.app.your", "TestPicture")), 

                new BeanDeserializerFactory(TestPicture.class, new QName("http://ws.app.your", "TestPicture")), 

                TestPicture.class, new QName("http://ws.app.your", "TestPicture"));


WOWebServiceRegistrar.registerWebService("ImageUpload", ImageUpload.class, true);


Where TestPicture is my EO class, and ImageUpload is my WS.

The WS class ImageUpload has two methods:

public static boolean uploadPicture(String datas);

public NSArray<TestPicture> getPictures();


The WSDL is shown correctly, but I don't see the definition for the Complex Type:

I really have no idea of what I am wrong... Googling the error, I've not found something useful...

Thanks in advance for any help!
