java.net.SocketTimeoutException: Read timed out issue

I'm going to assume that "com.Webservice.downloadFileAddPassword" is the package you created, and your web-service is Webservice.java. If this is true then you are having an error on line 192 of your Webservice.java. Its not that you may not be hitting the web-service, but the operation time or a process inside your web-service is timing out. Did you unit test your web-service?

I am reading in the stacktrace that you have an InputStream that you are calling which when trying to connect or read from the source, it is taking too long at which point it times out. http://docs.oracle.com/javase/7/docs/api/java/net/SocketTimeoutException.html

So basically: webservice is using an input stream that is taking too long. I don't think I know enough to just look at your stacktrace and give any more information.

Stack Trace as a more readable format:
