通过WSDL调用Web服务

Question

I have been following a tutorial to publish a web service which i have completed successfully

The wsdl can be found here - http://hotornot-hnwebservice.rhcloud.com/TomcatHotOrNot/messages?wsdl

The WSDL looks as follows;

<!--
 Published by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is JAX-WS RI 2.1.1-b03-. 
-->
<!--
 Generated by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is JAX-WS RI 2.1.1-b03-.

</definitions>

Ideally i want to use android in order to invoke my web service. My assumption that the WSDL should describe the service to give an indicator to how to call the web service.

Can anyone help as to how i would call this web service from android?

Thanks

Answer 1

The WSDL describes the service ie its operations and structure. It also specifies if it is available over HTTP etc. All this information is enough to call the service. However you still need to go code the actual call to service.

Read this tutorial on how to call a web service from android.
