Re: [Fwd: Re: Exception loading CXF service in Spring with HTTP Binding]

[Brad O'Hearne]

Dan,

I appreciate the reply, but I think you may have the wrong idea. I'm 
very patient, but this isn't a function of me, or something personal. It 
is the function of a deadline which doesn't really consider my own 
personal feelings in the matter, another API which presented an issue 
which necessitated the need to get out of WSDL-bound soap web services 
immediately, the fact that very little in this regard is documented in 
CXF, and the exception thrown gives no useful information to a user. 
With regards to the timing of my post and your read on my patience -- 
I've basically burned the better part of 2 days on trying to configure 
CXF / debug / scour Google / read API source / read the User's guide for 
direction on what is a standard advertised feature of the API, which I 
cannot find. The reason I'm asking the question with urgency is so that 
I *can* invest our project in CXF long term, not so I can get away from 
it. And I passed this urgency onto the list so that anyone with an 
answer would understand this urgency, realize its the difference between 
having another product built on the API, or not using it at all, and 
reply soon, since as you pointed out, it was the end of the working 
week, and might otherwise wait until Monday. If it were up to me, I'd be 
fine to wait a week for an answer. But it isn't up to me. It isn't some 
kind of personal affront. Please don't take it that way.

I have tried three different forms of the @WebService attribute. I have 
tried just:

@WebService
public interface ....

then I've tried adding a namespace:

@WebService (targetNamespace = "service/brad/com")
public interface ....

and then I've tried adding a service name

@WebService (serviceName = "UserService",
                       targetNamespace = "service/brad/com")
public interface ....

All three fail identically.

Thanks for your help. It is greatly appreciated. And again, my purpose 
was not to be impatient. I was faced with a choice of putting out an 
urgent call for help, and if things went well, getting to be a daily 
user of the API, or basically punting immediately. I opted for the 
former, as I want to use CXF, as it appears you guys have put together a 
great product.

Cheers,

Brad

Hi Brad,
Don't you think you're being a little impatient here? Your message is 
from 6
PM on a FRIDAY (now 12 AM Saturday) and pretty much everyone has gone 
home.
While I sympathize with your problem & timeline, I think you're being 
quite
unrealistic in your expectations. I'm the one who wrote the code and
probably no one else around really feels qualified to answer this 
question,
so everyone else is probably going to wait a reasonable amount of time 
for
me to come back online. And I've been busy travelling.

As to your error, it seems for some reason CXF isn't finding your
@httpresource annotation. What does the @WebService attribute look 
like on
your CustomerService class? You could possibly try adding a serviceClass
attribute to your <jaxws:endpoint> and see if that will help:

<jaxws:endpoint serviceClass="...IUserService"/>

Hello,

I don't want to cross the line on asking questions to the dev list, but
I'm in a bit of a bind here, and I need to get this worked out, and I
think that posting this to the dev list may be appropriate for the
following reasons:

1) It is in the realm where the documentation says the functionality
exists, but doesn't say how to configure (i.e. a hole in the
documentation).
2) The stack trace / error I am receiving I am guessing only a developer
is going to likely understand -- it makes absolutely no sense at a user
level.
3) The only reference I found to this error on Google was from last
month on the developer list.

The forwarded email explains my problem and stack trace, but in a
nutshell, I just need to configure annotation based, SOAP-Free, Restful
Http/xml services in Spring. Nothing tricky -- simple, standard,
boilerplate need. I am having no luck, as my service loading fails. The
stack trace is attached. Here is my web.xml file:

   @Get
   @HttpResource(location = "/users")
   ServiceResponse getUsers(ServiceRequest request);
}

Thanks in advance for the help. I'm to the end of my rope, with regards
to my timeline, and I need to get this working, and qualify CXF as a
service stack that can be used for this project, or else I'm going to
have to punt this weekend and incur a ton of work basically duplicating
what CXF already purports to do.

Cheers,

Subject: Re: Exception loading CXF service in Spring with HTTP Binding
I'm appealing to anyone out there who can please help me with this
problem. All I'm trying to do is standard configuration of a single
service, with a single method, using Http binding, using Spring. If I
cannot get this problem resolved soon, as much as I do not want to, I'm
going to have to punt usage of both CXF and XFire, which I am migrating
from. Simple, SOAP-free, RESTful HTTP service invocations configured in
Spring -- that's it. The documentation says that this can be done, but
doesn't give a complete description of how this can be done; Google
gives a reference from last month about this, but no answers, and the
API samples don't shed any light on it. It seems my configuration is
close, but I'm starting to wonder if Http Binding in CXF actually works,
as the there is little to no information available on it.

If anyone is in the know about how to get this to work, I'd greatly
appreciate it. I'm up against a deadline and I'll have to roll my own
service stack if I have to wait several days to get this resolved.

Thanks in advance for your help.

Brad
