Using RESTful services with J2ME client
Hi,
I'm working on application which consists from 2 parts: backend services and
mobile java client (J2ME). The main idea that server exposes some services
and mobile client uses them, pretty standard. RESTful web services looks
more lightweight and more flexible in this particular situation and I would
like to use Apache CXF implementation. So, everything is clear with server
side. But I have some questions regarding client side.
The main problem which I faced with that J2ME does not support all HTTP
headers.
(http://www.java2s.com/Open-Source/Java-Document/6.0-JDK-Modules/j2me/com/sun/midp/io/j2me/http/Protocol.java.htm
See setRequestMethod implementation.) So I cannot use "fully RESTful" way
but can emulate this by using method name in URL like /book/{id}/delete.
Does anyone use built-in CXF Client API with J2ME? Is it possible at all to
use for example HTTP-centric clients?
I know that I can build REST services client by myself, parse resulting XML,
etc. but built-in clients are really time saver.
Maybe someone had experience with similar project, I would appreciate any
suggestions.
Thanks,
Serge Barysiuk

JAXRS-aware clients like CXF JAXRS can register alternative providers, for
example, Aegis or XMLBeans or some other databinding can be used in CXF on
the client side.

Hi Sergey,
Thanks for your feedback.
That's exactly what I was looking for - _method parameter.
I've just realized that all HTTP clients use JAXB to marshall/unmarshall
objects, so I suppose it it's impossible to use them on client side (J2ME).
Thanks,
Serge

Hi Serge
You might want to set the following HTTP header :
X-HTTP-Method-Override : DELETE
CXF will assume that DELETE HTTP method was actually used.
_method queries can also be used. Some more info is here :
