How to access a web service using GWT?

[Dany]

Hi

I am new to GWT and looking at ways to access a web service from GWT
client.
Does GWT provide any infrastructure to make web service calls (both
synch & asynch)?

I appreciate any pointers to articles, code samples, etc.

Thanks

Hi Dany

You can use the HTTP client package to do it yourself (beware the
'browser origin' rule)
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/http/client/package-summary.html

if the WS is JSON compatible, you can use this fudgy method
http://www.gwtsite.com/how-to-access-web-services-with-gwt/

You can use ws-js
http://www.ibm.com/developerworks/webservices/library/ws-wsajax/

Or you can use gwt-ws
http://evolvis.org/projects/gwt-ws/

I haven't really checked any of these options out, just googlage. I
intend to look at gwt-ws first.

FYI, I am calling document style xml web services ofer http so need to
handle XML on the client, I am using piriti to make this less painfull

Hi,

I am trying to develop an application which would read an some data
from a local excel file, but gwt does not allow accessing local files.
So I thought 'd make a web service that would do the reading (of the
excel file) for me and return the values that I need. I have deployed
this webservice in a weblogic server (comes with Jdeveloper).

Would it be possible to give me a snippet of code/link which points to
a snippet of code on how to invoke the service from within a GWT
program?

Thanks!
