I have a Vaadin Project that I didn't wrote. I didn't do anything with Vaadin before. Now I have to implement an API and Web Services for further communication.
So my question is: Is it possible to create web services and a further URL structure to the project besides the Vaadin stuff?
Thank you for your answers.
Vaadin is just a User Interface framework - for the presentation layer.You can write your service layer separately from the presentation layer as usual. So you can use whatever framework or mechanism you are familliar with in java or better yet just add more web services in a same way the old ones are published to preserve consistency.

I need to design for searching for a file application in Java. I have planned to design it with
Socket
Web services with javaws
Which is faster in application which searches for file from a distributed system?
I'd go with option 2.
Primary Reasons
Less coupling between client and server
Ability to scale
Ability to incrementally add new apis
Pre-built libraries that will help you get this done fast.

I know to create Restful web service but I don't know how to implement restful facade in java.
I would appreciate if you share some links or examples of implementation.
Your question isn't that specific, so hard to provide a targeted suggestion, but I've been using spring mvc to create restful webservices in java with a fair amount of success. Spring have an examples project, which it claims "demonstrates the capabilities of the Spring MVC web framework through small, simple examples":

I am new to the restful web services. So my knowledge is minimal about the topic. I am developing a restful service in Java & I want to call an Amazon web service API from inside the service. Is this possible? How many ways can I do this?
There's no difference to any other java program. Just call the URL using a HTTP Client. A popular one ist the HttpClient from Apache HttpComponent.
Take a look at Jersey framework. If I understand you correctly, you should find this section of the documentation useful.

MVP and MVC are mostly used patterns in Java and other languages. Is there any other list of patterns working like MVC and MVP?
Well I cant speak for Java but with big iOS projects (often using Core Data) you normally expand the MVC pattern to MVCS (Model-View-Controller-Store). The Store is responsible for fetching data provided by external sources and providing data to controllers. You do this to not mess up your controllers in such projects.
But for normal projects MVC is your way to go.

I would like to host my own version of the boilerpipe web API (http://code.google.com/p/boilerpipe/). The appspot site is http://boilerpipe-web.appspot.com/
I would like to self host it. Can someone give me directions on how to use the Boilerpipe JAR to create a webpage ?
I am the author of boilerpipe.
Boilerpipe's demo web application boilerpipe-web is not part of the boilerpipe-core jar.
To imitate its functionality you will need to write some Java Servlet around boilerpipe-core.
I'll probably release the source of boilerpipe-web at some point, so you don't have to bother with.
