> In RESTUtil.java in the processPostRequest() method:
> msgContext.setEnvelope(soapEnvelope);
> msgContext.setProperty(HTTPConstants.HTTP_METHOD, HTTPConstants.HTTP_METHOD_POST);
> msgContext.setProperty(HTTPConstants.CONTENT_TYPE, contentType);
> msgContext.setDoingREST(true);
> It seems that an extra line should be add:
> msgContext.setEnvelope(soapEnvelope);
> msgContext.setProperty(HTTPConstants.HTTP_METHOD, HTTPConstants.HTTP_METHOD_POST);
> msgContext.setProperty(HTTPConstants.CONTENT_TYPE, contentType);
> msgContext.setDoingREST(true);
> //ADD THIS LINE
> msgContext.setProperty(MessageContext.TRANSPORT_OUT, response.getOutputStream());
> Otherwise the TRANSPORT_OUT is not set and the service won't be able to output the response, producing a stack trace like:
> java.lang.NullPointerException
> at java.io.Writer.<init>(Writer.java:70)
> at java.io.OutputStreamWriter.<init>(OutputStreamWriter.java:79)
> at org.apache.axiom.om.impl.MTOMXMLStreamWriter.<init>(MTOMXMLStreamWriter.java:74)
> at org.apache.axiom.om.impl.llom.OMNodeImpl.serializeAndConsume(OMNodeImpl.java:380)
> at org.apache.axis2.transport.http.CommonsHTTPTransportSender.sendUsingOutputStream(CommonsHTTPTransportSender.java:256)
> at org.apache.axis2.transport.http.CommonsHTTPTransportSender.invoke(CommonsHTTPTransportSender.java:210)
> at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:589)
> at org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver.receive(AbstractInOutSyncMessageReceiver.java:43)
> at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:454)
> at org.apache.axis2.transport.http.util.RESTUtil.invokeAxisEngine(RESTUtil.java:150)
> at org.apache.axis2.transport.http.util.RESTUtil.processPostRequest(RESTUtil.java:100)
> at org.apache.axis2.transport.http.AxisRESTServlet.doPost(AxisRESTServlet.java:43)
> For the moment actually the response argument is not used at all in the processPostRequest() method. In contrast, the processPostRequest() method does perform this step.
