Subscription to SOAP web service

We need a piece of code (in Java) that will register for a push-based data service, as described in the following protocol: [login to view URL](NP2015-2a).pdf, please see chapter 3.2.1. The software needs to send a request to start delivery of data and deal with a number of scenarios (connection loss, reconnect, etc) as described in the document chapter 3.2.1 and all subparagraphs. The software should receive the data. Every piece of data needs to be stored as a file in a configurable local directory. Processing the XML itself is not needed. A live URL for the subscription service and user/password are available so testing with the real thing is possible and necessary. The end product is the code (in Java). In the end, we will integrate this piece of software into our software system ourselves and add the parts of code that deal with further processing of the data. The code needs to be well written en well commented in English.
