Alex Rodriguez commented on AXIS2-795:
--------------------------------------
I would like to see this fixed as well. Cleanup should not be called on the
transport sender because the content from the underlying input stream
encapsulated within the returned OMElement may not have been fully read yet.
This happens in the case of large attachments or soap messages sent over a
chunked input stream.
> Returning a MTOM message causes IOException (closed stream)

> Key: AXIS2-795

> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: databinding
> Affects Versions: 1.0
> Environment: JDK 1.4.2_06
> Reporter: Wolfram Kaiser
> Assignee: Thilina Gunarathne

> When accessing an attachment sent via MTOM on the client side I get the
> following exception:
> org.apache.axiom.om.OMException: javax.mail.MessagingException: Error in
> input stream; nested exception is:
> java.io.IOException: Attempted read on closed stream.
> at org.apache.axiom.attachments.Attachments.getPart(Attachments.java:462)
> at
> org.apache.axiom.attachments.Attachments.getNextPart(Attachments.java:359)

> org.apache.axiom.om.impl.mtom.MTOMStAXSOAPModelBuilder.getDataHandler(MTOMStAXSOAPModelBuilder.java:151)
> at
> org.apache.axiom.om.impl.llom.OMTextImpl.getDataHandler(OMTextImpl.java:341)
> The client stub was generated using the default / no data binding (-> direct
> Axiom access). I believe the error is in the generated stub:
> public org.apache.axiom.om.OMElement echoPdf(org.apache.axiom.om.OMElement
> param48) throws java.rmi.RemoteException {
> ...
> _messageContext.getTransportOut().getSender().cleanup(_messageContext);
> return (org.apache.axiom.om.OMElement) object;
> }
> The cleanup() seems to close the InputStream for the PDF/attachment while the
> attachment has not been loaded in Axiom. Thus, when accessing the attachment
> in the OMElement returned by MyStub.echoPdf() the aforementioned exception is
> thrown. I would argue that the pull mechanism of Axiom fails in cases where
> the associated InputStream has been closed while the generated stub has done
> its processing already.
> The following simple - but rather ugly - work-around seems to solve the
> problem:
> public org.apache.axiom.om.OMElement echoPdf(org.apache.axiom.om.OMElement
> param48) throws java.rmi.RemoteException {
> ...
> org.apache.axiom.om.OMElement omElement = (org.apache.axiom.om.OMElement)
> object;
> // retrieving the content of a OMTextNode will load the associated data
> so it can be accessed
> // even after the InputStream from this web service call has been closed.
> omElement.getText(); // or omElement.toString();
> _messageContext.getTransportOut().getSender().cleanup(_messageContext);
> return omElement;
> The getText()/toString() has the effect that all binary data from the web
> service call is loaded in the Axiom objects so they can be accessed in the
> client code which uses the MyStub.echoPdf() method.
