POST request from a REST client will cause a NullPointerException in the service
--------------------------------------------------------------------------------
Key: AXIS2-787
URL: http://issues.apache.org/jira/browse/AXIS2-787
Project: Apache Axis 2.0 (Axis2)
Type: Bug
Components: core
Versions: 1.0
Reporter: Kent Tong
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)

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.
