Web Service using MySQL and Hibernate Tutorial

Are there any good tutorials around which explain how to configure Hibernate with MySQL which can then be used to run a web-service? ideally so an android application can connect to it via http:// and bring back results.
I am preferably looking for a REST web service using the JavaEE framework.
Tutorials for either Eclipse or Netbeans are fine. I can't really find any good tutorials that explain this combination. Do I have to use my own initiative when looking at hibernate and web service tutorials separately? which is fine as long as I know i'm not missing something here..

Yes, you should look at hibernate and web service tutorials separately.
Hibernate is a framework that focus on the data access layer, official page.
And eclipse comes with a wizard, that allows you to create web services from a class easily (just a few clicks)
I would start first researching on hibernate (first find out if that is what you wanna use...)
Then the web service.

https://netbeans.org/kb/docs/web/hibernate-webapp.html uses hibernate and mysql, not sure if it exposes it as web service. Note you can register MySQL, create a web app, then use the REST Services from Database file template to generate everything. I think you can choose Hibernate as your persistence provider there.

How can I get started building a Facebook application with a Java server backend?

I want to utilise the Facebook JavaScript API in the client, but manage app logic and configuration on the server through REST web services. I've tried a lot of tutorials out there, but so far I haven't seen one that actually works.
What do you recommend as a server / web framework?
What technology should I use for my REST endpoints?
How can I host this application in a place where facebook will "see" it as a valid app?
I'm looking for a comprehensive tutorial or set of recommended practices to get started.
Thanks

I just so happened to create a blog series that takes you through EVERYTHING you will need. The articles:
Setup Eclipse (IDE) and JBoss AS7 (server)
Setup other JBoss Tools including Forge
Setup JAX-RS Web Service in Java using Forge (very easy!)
Setup account to Host the site for FREE with OpenShift
Setup an entire sample Facebook App
This blog series should be EXACTLY what you're looking for. You can find the first of three articles here:
http://ocpsoft.org/opensource/creating-a-facebook-app-setup-and-tool-installation/

I would recommend going with Spring Social module with has a good abstraction of the Facebook API.
You could then expose these services via REST with Spring Web Services or Jersey.
I am not sure about the hosting. Facebook should see it as a valid application no matter the host. Even your development computer/localhost cando it.

Calling Java web service from .Net

I need to call Java web service from .Net application and that web service should accept the parameters from .Net but am not sure about the procedure. If anyone have some idea then please let me know.

.NET web service is SOAP web service. Just get WSDL, generate stubs and use it.

You should get the WSDL first, then using Eclipse (I would suggest Netbeans) you generate/create the Stubs and call the service. It is really nothing fancy at all. Once you have the WSDL the rest (how you generate the classes using Netbeans) is really covered a lot online.

How to implement REST in my Web Application. I want to make a rest API for my website?

I am working on an enterprise application and need to provide services to mobile app using REST.
I want to implement or build a REST API for my website using which I can build client side application as well as provide services to the mobile app for my website.
I have very less idea about it and for technical specification.
My website uses Spring Framework and is build upon Java.
Kindly guide me through.

You can find some resources here about developing REST applications with Spring MVC

Java-ws tomcat invoke methods through http?

I made a web project in Java, using Java-WS.
How can I invoke service methods through HTTP only.
I don't want to generate (or worse write) any java web clients, and similar stuff.
I'd just like to invoke the method with a HTTP request.
And parse the result (manually) from response.
In .NET web services I invoke methods just with:
http://serviceUrl/serviceName.asmx/operationName?parametars=...
How to do the same thing in java + tomcat?
Edit: Let me rephrase my question.
So this is what I have done so far:
Created a web application (btw. using NetBeans IDE)
Added all the necessary source files
Added web service classes with WebMethods defined
I deploy the app on tomcat and it deploys fine.
Now, what do I need to do to be able to invoke my WebMethods via HTTP?
Typing:
http://localhost:8084/MyService/MyMethod
doesn't work.
Sorry if this is a stupid question, but I'm not really a Java guru, I've been working mostly on .NET.

Multiple possibilities:
use new URL(url).openConnection().getInputStream()
use apache http components
use a REST client (if you invoke restful services), like http://code.google.com/p/rest-client/">this, or these. Or spring's RestTemplate

In this case, if you want to do an HTTP Web Service that returns an HTTP 200 Web Response, why not look at doing a RESTFul application?
JavaWorld briefly explains the role/use of REST. There's been similar questions on REST tutorials in SO. I hope this helps you.

Apache CXF has a 'plain http binding', but we recommend that people write JAX-RS services, instead. They are very, very, simple. However, the plain HTTP binding is there and supports GET.

I generate a RESTful Web Service in NetBeans by clicking on "Generate SOAP-over-HTTP Wrapper" in my service context menu.
It generated successfully, compiles and deploys fine.
But I still can't figure out how to make a HTTP invoke
