Call a web service from java (eclipse)

You make an httpservletrequest:
http://docs.oracle.com/javaee/6/api/index.html?javax/servlet/http/HttpServletRequest.html

Most people use the Apache commons HttpClient as a wrapping package, since it handles redirects and cookies:

Thank you for you reply, but I'm looking for an example or tutorial that shows me step by step how I simply can call an external web service from java (eclipse).

Hi mrcoffee365,
Thank you for the link. I have tried to execute the code, but I'm receiving the following error message:

Exception in thread "main" java.lang.ClassCastException: org.apache.xerces.dom.DeferredDocumentImpl cannot be cast to javax.swing.text.Document
      at WebServiceCall.parseXmlFile(WebServiceCall.java:126)
      at WebServiceCall.getWeather(WebServiceCall.java:93)
      at WebServiceCall.main(WebServiceCall.java:33)

The code is attached.
Your assistance is greatly appreciated.
WebServiceCall.java

The exception is pretty clear.  This line, 126 in your program:
  return (Document) db.parse(is);

is trying to cast the results of DocumentBuilder db.parse method to a Document type.  So check the return type of the db.parse method, and cast it to the correct type or convert it to what you need.

Thanks mrcoffee
