Java EE (Java Enterprise Edition) General Discussion

I have a SOAP service running and responding to SOAP requests normally. However, when I tried to validate the response against the WSDL in SOAPUI 1.7.6, it gave me error saying:(see wsdl and response xml in the end of this post)
line 4: Expected element 'offer' instead of 'offer@http://www.conceptwave.com/pt_pcapi' here in element offers@http://www.conceptwave.com/pt_pcapi

It seems the targetNamespace in my WSDL schema only applies to its direct "element"-type children nodes. If it's a non-element node, for example, "complexType" or a non-direct children , for example "offerCode" element under "sequence" node ( which is under "offer" complexType), the validator considers them no-namespace nodes, therefore complains when receiving a response containing these nodes with namespace(/prefix).

Anybody can shed some light on this? Thanks in advance.
