Web service Details

Project name RestFulWS

package Name rest.ws.server

class Name helloAndroid

Method Name getGreetingMsg(string argument)

any help will be appreciated.

Answer 1

Simply with an HTTP client like AndroidHttpClient .

EDIT: RESTful web service is accessible through URL like:

http://yourserver/someservice/<categoryID>/<objectID>

So, you can test your webservice from a web browser like Internet Explorer or Mozilla Firefox.

Then, on Android, use HTTP Get request and the AndroidHttpClient.

Don't forget to set the INTERNET permission in your AndroidManifest.xml too

Answer 2

It depend on the Web server you are using because each type of server will have its own URL to service hosted on it. If you are using JBOSS server then your URL looks like this IP:PORT/projectname/webservicename/method name

Answer 3

Sounds like you're not sure how to approach your own API. If your API supports GET, then open a web browser and try some GET commands. Once you have a GET statement working, work through this tutorial: http://sarangasl.blogspot.com/2011/06/android-login-screen-using-httpclient.html .

Once you're set with POST, turn off GET in your webserver.

Good luck!
