I changed the wsdl by hand and it works now, but i also investigated this topic a little further. No matter what i change the return type to, JBossWS always generates the same result (and that's a bug imho): | @WebMethod | public Integer[] GetSteps(String ugid) { | ... | } | | or | | @WebMethod | public int[] GetSteps(String ugid) { | ... | } | give both | ... | <xs:schema targetNamespace="http://jaxb.dev.java.net/array" version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> | <xs:complexType final="#all" name="intArray"> | <xs:sequence> | <xs:element maxOccurs="unbounded" minOccurs="0" name="item" nillable="true" type="xs:int"/> | </xs:sequence> | </xs:complexType> | </xs:schema> | ... | <message name="QMWebService_GetStepsResponse"> | <part name="return" type="ns1:intArray"> | </part> | </message> | in the int[] case i would suppose nillable="false", else nillable="true", right?
