title: How to call an external web-service from Joomla
body: <p>I am going to create a webservice (I think in java) which role is to treat a picture (IN) and to return a result (OUT). I would like to use that web service from my Joomla website.
  The process will be :</p>
  
  <p>1- upload of a picture from the website</p>
  
  <p>2- we call the web service to treat the picture</p>
  
  <p>3- we receive the result and display it in a new page</p>
  
  <p>I really don't know how to proceed to do these 3 steps. My first question is : how do I call a web service with Joomla (2.5)?</p>
  
  <p>Thanks</p>
