Does anyone worked with GWT connecting to Web Services in the server side?

[nacho]

Hi, i'm trying to develop an application with GWT in wich one i have
to get the data from WS that are hosted on a different server.

I was googling about that but there not so much examples.

Does anyone did that?

Sorry my poor english :P

What do you mean with "different server"?
I do something like that; I use RequestBuilder classs (I do not use
RPC and ASyncCallBack) to make request to server; date are sent and
received in XML format.

The problem is the following.

I have an api wich connects to the differents WS and gave me all the
DAOs. But when i try to use the API in the server side, in a
ServiceImpl class i get the followoing error:

javax.xml.ws.Service is a restricted class. Please see the Google App
Engine developer's guide for more details.

This problem i think is because this class is not in the Appengine
Whitelist (http://code.google.com/appengine/docs/java/
jrewhitelist.html) but it dosnt have to be a problem if i want to
deploy the application in a Tomcat Server for example.

Buuuuuuut because of the above error, my problem is that i can't make
the GWT compiler to get run and compile the js files.

How could i do?

You can do that if you disable Google App Engine. If you are using the GWT Eclipse plugin, there is a setting to disable App Engine.

Hi,

I use tomcat to connect to a variety of webservices. Essentially it
works as a client to them. I don't deploy to Google AppEngine though.
But it does work if you control the server that you host the tomcat
instance on.

I use Axis 2 to communicate with web services on the server. The
ServiceImpl and RPC gives the results to and from the GWT client.
