Transfering a Parameter to Execute the Webservice

The webservice needs two parameters: a username and a password (crypted). If the user has more than one clients assigned, the client is needed too. Optionally it is possible to add parameters which the workflow expects - a ticket number for instance.

Each parameter must be put in the instance of the class 'KeyValuePair'. And each instance of the class KeyValuePair must be put in an ArrayList.
