NullPointerException after cxfEndpoint.getOutInterceptors().clear()

[Landslide <xi...@landslide.com>]

If I have a CXF client which is set as
(BindingProvider.SESSION_MAINTAIN_PROPERTY, true), I do not want the client
to send the following <soap:Header> tag for all subsequent requests after
the first successful request:

<soap:Header>
<wsse:Security
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
soap:mustUnderstand="1">
</wsse:Security>
</soap:Header>

If I do so by:
cxfEndpoint.getOutInterceptors().clear();
the CXF API gives me an erorr as below: 
Mar 5, 2008 4:20:14 PM org.apache.cxf.phase.PhaseInterceptorChain
doIntercept
INFO: Interceptor has thrown exception, unwinding now
java.lang.NullPointerException

If I use an SOAP client coded with the Axis2 API, I can do so after the
first successful request with no issue by calling:
client.disengageModule("rampart");

It seems to me that the CXF API should check if the list of OutInterceptors
is empty or not, and would do nothing if it is indeed empty.

Thanks for your help, Dan!

Doing the following does get what I wanted:
     cxfEndpoint.getOutInterceptors().remove(wss4jOut);
     cxfEndpoint.getOutInterceptors().remove(saajOut);

The issue is that you are probably clearing out a bunch of interceptors 
(like all the soap interceptors) that need to be there.   Most likely, 
the null pointer is not due to it being empty, but due to something else 
expecting a particular interceptor to be there.

Before calling clear, can you see which interceptors are there?   In 
general, only remove the interceptors that you added.
