Roberto commented on AXIS2-1964:
--------------------------------
Hi all,
in these days I'm facing this same issue of :
java.lang.NullPointerException
at
com.ctc.wstx.sw.BaseNsStreamWriter.doWriteDefaultNs(BaseNsStreamWriter.java:528)
at
com.ctc.wstx.sw.SimpleNsStreamWriter.writeDefaultNamespace(SimpleNsStreamWriter.java:111)
at
com.ctc.wstx.sw.SimpleNsStreamWriter.writeNamespace(SimpleNsStreamWriter.java:119)
with Axis 1.1.1. ( I don't know if on Axis 1.1 would be worked ).
If I change from:
_operationClient.getOptions().setAction("");
to:
_operationClient.getOptions().setAction("http://localhost:8080/axis2/services/EMServerImplService";);
I still get the same NPE.
With a deeper analysis, I found that the HTTP request is sent to the server;
see below the server-side exception:
------------------------------------------------------------------------------------------------

The server returns an error page to the client, which cannot deserialize the
response or something like it I think, so it get an NPE.
Is there any workaround?

> sure whether the Bug 1856 and above problem is related.
