Jdeveloper 11g : Generating webservices with streaming attachments support

Question

Hi,
We are trying to create a Java Webservice with support for streaming attachments. In 10g we are using the Attachments API from the oracle.webservices.attachments package.
In Jdev 10g we were doing it the following way:
public String getXMLFile(String name,String fileName,Attachments atts) throws RemoteException
try
AttachmentFactory factory = AttachmentFactory.newInstance();
Attachment imageAtt = factory.createAttachment(fileName, "text/plain", new FileInputStream(fileName));
atts.getOutgoingAttachments().addAttachment(imageAtt);
} catch (Exception e) {
System.out.println(e.getMessage());
return "Hello " + name;
This webservice is deployed in Oracle AS.
How do we do it in Jdev 11g and we want to deploy the service in WLS 10.1.3. If we try to create a webservice over this class in Jdev 11g we get the error :"no-arg default constructor not present".
Any pointers would be highly appreciated.
Thanks and Regards,
Pritom

Hi Vishal,
I created the class as mentioned in the link. But when I try to test the web service, I get the following error :
weblogic.application.ModuleException: [HTTP:101216]Servlet: "oracle.apps.ddr.testFileDownload" failed to preload on startup in Web application: "Application7-Project1-context-root".
javax.xml.ws.WebServiceException: Annotation @com.sun.xml.internal.ws.developer.StreamingAttachment(parseEagerly=true, dir=, memoryThreshold=40000) is not recognizable, atleast one constructor of class com.sun.xml.internal.ws.developer.StreamingAttachmentFeature should be marked with @FeatureConstructor
     at com.sun.xml.ws.binding.WebServiceFeatureList.getWebServiceFeatureBean(WebServiceFeatureList.java:176)
     at com.sun.xml.ws.binding.WebServiceFeatureList.parseAnnotations(WebServiceFeatureList.java:148)
     at com.sun.xml.ws.binding.WebServiceFeatureList.<init>(WebServiceFeatureList.java:113)
Any ideas on how I can make it work ?
Thanks and Regards,
