Re: Web services and J2ME

You're right Nathan, this is the smart way... ;-)

Very often, using the "fully politically correct" method to access to a SOAP
server induces a heavy and slow solution that is not acceptable on a mobile
device.
Nathan's suggestion is very similar to the 2nd one suggested by Emmanuel
(may be a bit heavier on the mobile side) but it does not need any server
side effort.
We have already used such a method in a real application. If you wish, you
can read  http://www.wapaka.com/wapaka/include_Webservices/WebServices.pdf :
this paper is bound to our proprietary product but the method explained
there is quite generic.

Since you presumably know the finite set of SOAP methods you will be
calling, you can hard-code the request strings on the client-side, and just
replace the variables with your dynamic request data. You can approach the
responses in the same way- just do some basic sax XML parsing instead of
worrying about the whole SOAP structure.

Obviously, you will be losing the full power, flexibility, and architectural
integrity of using KSOAP (or a similar SOAP stack), but sometimes in this
crazy embedded world, you have to give that up in exchange for efficiency.

Regards,
  Nathan
