Hi! I get the same error. If I change the List to ArrayList the error is gone but the types generated in the wsdl are empty. One has to write an adaptor and marshall/unmarshall the array list somehow? Shouldn't this be done automaticaly for Lists? I hope someone can clarify things for me in this matter, thanks in advance.
