Thanks for the workaround, I had the same problem
:-)

Matthew,
This is a bug that will be fixed in the next WO update. In the
meantime, the workaround is to call:
public static void registerWebService(String webServiceName, Class<?
> webServiceClass,String[] allowedMethods, boolean isRPC) and
passing 'null' for the allowedMethods parameter.

Starting with the recent release of 5.4.1, I have encountered a
strange
anomaly when attempting to register web services using the methods
described
in the “Web Services Programming Guide”
<http://developer.apple.com/documentation/WebObjects/Web_Services/>
Specifically, when invoking the following during Application
initialization...
WOWebServiceRegistrar.registerWebService(MyWebService.class, true);
...this statement generates an error that resembles the following:
[2008-2-15 20:7:12 CST] <main> java.lang.NullPointerException
at
com
.webobjects
.appserver.WOWSDDRegistrar.registerWebService(WOWSDDRegistrar.
java:225)
at
com
.webobjects
.appserver.WOWebServiceRegistrar.registerWebService(WOWebServi
ceRegistrar.java:46)
at Application.didFinishLaunching(Application.java:56)
[more...]
The function didFinishLaunching, line 56 is where the registration
statement
above was called. So, there is a NPE being generated somewhere in
the
function registerWebService(Class<?> webServiceClass, boolean
isRPC) within
the WOWSDDRegistrar class.
The WOWSDDRegistrar class appears to be BRAND NEW starting with
5.4.1; my
hunch is that there is an untested case somewhere in there when the
value of
isRPC is true. When isRPC is false, the registration fails, but
not because
of an NPE (consistent with 5.4.0 and earlier).
This is a bug that I hope can report soon so that it can be fixed
in a
future point release, but until then, since 5.4.1 is distributed
with the
10.5.2 server update, some end-users installing our WO apps are
starting to
run into this problem and I would like to offer a work-around
Is there someone who has a better idea of the internals of
WOWSDRegistrar
who can help me fashion some kind of work-around?
Thanks in advance...
