I am quite confused with these terms.
As far as I understand
Middleware provides the connection between devices/applications present in heterogeneous system.
Web services provides the methods through which the message can be transferred using the connection developed by middleware.
Am I right?
Someone has already asked this before, you can check this post out!

I'm sure I sound like a total noob with this question, and I've looked at a couple posts that are basically asking the same question in the title, but the body didn't give anything helpful to my skill or knowledge level.
In this post the OP mentioned that they did some "digging and drilling" to find out that there was a web service in REST format. In another post I found that the OP was using "web console" to look at the activity of a website they were visiting.
I would really like to have more knowledge and methods for finding web services that I can reference and use is some of my new or updated applications, whether RESTful or not. In summary, how do I "dig and drill" to find that a site has a web service I can use programmatically?
The only sensible way to find web services that you can use is to ask.
If the service is intended for your use, then you will be told that.
If the service is not intended for your use, then you will be told that.
If you use a service that is not intended for your use, then that will generally be a bad thing.
This might be a silly question on this site, but I want to learn more about it.
Being in the Software Engineering field, I have come to know that it's useful to get acquainted with Web-Services. I am trying to understand it. To do so, I must know the difference between a Web-Service and a Application-Service in simple terms.
I have heard about SOAP & REST Services.
For a newbie like me, its overwhelming to understand these concepts when I search them in Google.
How to understand these things better and in what order?
I think it's a great and simple question which usually confuses most of developers. What is Application Service and what is web Service?
Web service is a common term which you can find easily on the internet. Although some time they cross each others boundaries but here is a simplest explanation I can think of:
Application service or Application Layer is an abstraction layer reserved for communications protocols and methods designed for process-to-process communications. Application layer protocols use the underlying transport layer protocols to establish host-to-host connections.
Some time you can also use Application Service to define method calls within your application.
WebService: Any application or method which can be accessed by web is a Webservice. You can also say: anything available on the web is WebService.
There are three common web service architectures:
RESTful resource-oriented,
RPC-style e.g. SOAP
REST-RPC hybrid. 90% of the web sites use this unknowingly e.g. http://mysite.com/get/pictures?tag=birthday :)
I'm really new in Java Web Service. I can say that my knowledge level is only 10%. Can somebody please give me a HelloWorld Example of JAX-WS (client - service) with explanations?...
This might be a common question and perhaps a duplicate one too. But I would like to provide some links which might get you started.
This mkyong blog has good explanation with all the necessary examples.
Another blog which has provided two different articles for setting up the server and accessing it with the client.
You can also search it in google and get plenty of references to look.
Hope it will help you get started.
EDIT:
Another Dzone article that also has provided an example.
All these examples are JAX-WS.
Or oracle tutorial:

I am trying to set up a web store using magento on a SOA Architecture. So I intend to use all of the functionalities through the API connecting it with mule ESB.
However on my research I have read that the magento API is Silly Slow. And now I am wondering if it actually can handle the requests of an entire website.
Has anybody done something like this before? Can it actually work? If not, is there a workaround?

No, it is not viable to setup a store using only Magento's SOAP and RPC APIs. THat is not the intention of these APIs.
There are examples where people have done what you are looking for such as http://www.yireo.com/software/magebridge
They claim to be 40% faster than native Magento.
I've tried the tool, and it is quite functional.
I know what is soap,wsdl and uddi.
But what is the relation between them and how to establish the relationship in code.
It will be good if someone can post a sample code which has all of these.
Thanks in advance.
SOAP is the XML-based protocol used to send and receive web service messages. WSDL is the XML-based language used to describe the format of the messages, and the details of the interaction with the service.
UDDI is not used very much. It sounded like a good idea at the time it was invented, but turned out not to be useful.
