Changing HandlerChainBuilder line 119 from
LOG.log(Level.FINE, "loading handler",
trimString(ht.getHandlerName().getValue()));
to
LOG.log(Level.FINE, "loading handler",
trimString(ht.getHandlerClass().getValue()));
fixes the problem and allows the service to be exposed as WS.
> Deploying a JAXWS Service with a HandlerChain specified causes NPE

> Key: CXF-1529
> URL: https://issues.apache.org/jira/browse/CXF-1529
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 2.0.5
> Environment: Windows XP.
> Reporter: Scott Paisey
> Assignee: Sean O'Callaghan
>
> When attempting to deploy a simple JAXWS service with a HandlerChain
> specified, HandlerChainBuilder.buildHandlerChain() line 107 throws NPE.
> PortComponentHandlerType.getHandlerName().getValue() causes the problem as
> handler name is null.
> Annotations used in Service implementation:
> @WebService(
> targetNamespace = "com.test.service",
> endpointInterface = "com.test.service.HelloService"
> )
> @HandlerChain(file = "/com/test/service/proxy/handlers.xml")
> handlers.xml file is packaged in the same jar as the service implementation
> and is not being read from disk.
