Description

I have got NPE when iterating multiple attachment using API method isReadyToGetNextStream() and
getNextStream()
java.lang.NullPointerException
at org.apache.axiom.attachments.MultipartAttachmentStreams.getNextStream(MultipartAttachmentStreams.java:63)

It is seem as even stream comes to end ,the boolean value of isReadyToGetNextStream() is true;

Java Code

Attachments attachments = null;

if (this.opcts != null)

{ attachments = (Attachments) this.opcts.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE).getProperty(MTOMConstants.ATTACHMENTS); }

else

{ throw new AxisFault("Message context not set/Attachments not set"); }

// Get image data
IncomingAttachmentStreams streams = attachments.getIncomingAttachmentStreams();
int i = 0;
while (streams.isReadyToGetNextStream()) {

OMElement file = fac.createOMElement("file" + (i + 1), null);
IncomingAttachmentInputStream stream = streams.getNextStream();
if(stream !=null)

{ byte[] data = IOUtils.getStreamAsByteArray(stream); //setting response OMText omText = fac.createOMText(new DataHandler(new ByteArrayDataSource(data)), true); file.addChild(omText); elem.addChild(file); }

}

}
