A CE consultant working with me is having problems calling a simple Web
Service (IIS running on XP Pro for our test case) from a Smart Device
Application using a web reference. Any attempt to call a method, any method,
results in a WebException throw on the CE device.

Please confirm that there is no inherent problems calling Web Services from
CF 1.0 on HP iPAQ 4700 series PocketPC.

I'm convinced that its a security issue on the IIS side.
 
There are no problems with WS on CF running on 4700. Most common problems
are:



1. WS was running on dev box and is referenced as 'localhost'. Change URI to
point to the server.

2. Network setup is incorrect. Use IE on device to make sure you can reach
WS. Change your network setup as needed.

3. Security issue. Make sure you're using supported authentication (Digest
or Basic) for this WS and credential are set correctly.



Best regards,



Ilya

I have a number of apps working on iPaq 4355s and on the 4700 series which
run CF 1.0, SqlCE,
and that use web services extensively.

I would recommend installing SP2 or SP3 of the Compact Framework however -
there was
some work done on the web services support in these service packs.

And to add to the previous replies - please make sure that you provide the
exception information, since it makes remote diagnostics possible, thus
giving an opportunity to assist you better
 
I've been avoiding posting this message all day long. Ok, here it goes:

The consultant is trying to convince me that for CE to make use of a web
service, then you must use a web application and have the web app call the
web service.
In other words, attempting to call a web service from a "smart device
application" will not work.

This make no sense to me. Please tell me this is wrong. ;-)
