> We use Axis 1.4 in an WLS 8.1 environment. There are no TransportReceivers
> registered in axis2.xml.
> After server start or redeploy it is impossible to get an answer to a POST
> request via SSL. We see following exception:
> @|27.06.2008 11:01:53|ERROR|org.apache.axis2.transport.http.AxisServlet|

> After the first sent GET there is no problem anymore.
> The NPE is thrown here:
> TransportListener listener = msgContext.getTransportIn().getReceiver();
> Seems that msgContext.getTransportIn() returns null.
> Maybe this is because AxisServlet only resisters itself as TransportListener
> for HTTP scheme. From AxisServlet.init(ServletConfig config):
> TransportInDescription transportInDescription = new
> TransportInDescription(Constants.TRANSPORT_HTTP);
> transportInDescription.setReceiver(this);
> listenerManager.addListener(transportInDescription, true);
> Would it be possible to register AxisServlet here also for HTTPS?
> A GET request never fails because doGet() does an
> agent.initTransportListener(request); but doPost() never does.
> I know, there was already an Jira issue AXIS2-3141 which addresses the same
> thing. But the attached patch seems to be only a workaround.
