mtom return always attachment witi content-type = "image/png" - java-metro-framework

Question

In my example of soap mtom optimization I've realized an project on Tomcat 7, metro (glassfish) in which I've got:
XSD
<xs:element name="retrievePicture" type="tns:retrievePicture"/>
<xs:complexType name="retrievePicture">
<xs:sequence>
<xs:element name="inImageNumber" type="xs:int"/>
</xs:sequence>
</xs:complexType>
<xs:element name="retrievePictureResponse" type="tns:JPEGPictureType"/>
<xs:simpleType name="JPEGPictureType"
xmime:expectedContentTypes="image/jpeg">
<xs:restriction base="xs:base64Binary" />
</xs:simpleType>

#WebService(wsdlLocation="WEB-INF/wsdl/PictureManagerService.wsdl")
#MTOM
public class PictureManager {
....
#WebMethod(operationName = "retrievePicture")
public Image retrievePicture(
#WebParam(name = "inImageNumber") final int inImageNumber) {
java.awt.Image theImage = null;
//logic for return Image according request
return theImage;
}
}
My project consist of download JPEG image according of request.
In Soapui I get the following raw response:

The problem is that the content type "image/png" is wrong as I would have expected "image/jpeg"

Answer 1

As i just had a similar issue, I don't think that this snippet will generate a DataHandler:
<xs:simpleType name="JPEGPictureType"
xmime:expectedContentTypes="image/jpeg">
<xs:restriction base="xs:base64Binary" />
</xs:simpleType>
I'am still trying to find out why, but meanwhile you can do the same as me and I think that will help you too. Just use directly the element retrievePictureResponse instead of working with xs:simpleType, so you can use this code :
<xs:element name="retrievePictureResponse" type="xs:base64Binary"
xmime:expectedContentTypes="image/jpeg" />
