1. Official information: http://www.w3.org/2002/ws/\n2. If you are going to use java - http://java.sun.com/webservices/ will show you how you can use it.\n3. Here is a short example: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Session3.html

To know what services are running on the OS, like Web Servers, and try to find a way to enter. You can collect information about the service, what program is running, the OS (Win, Lin, ..) but thinking more. and other data....\n\nYou can scan with NMAP, one of the best program for that, it is free and its available for multiples platforms.\n\nYou can solve the problem installing a good firewall, making a good configuration of the OS and applications.

As a category, I think that web services will be widely used in the near future.\n\nAs a specific language (or group of languages, really), I think that AJAX will be much more prominent in the near future.

It's basically an invetory of clients or contact, i have developed one using c#, asp.net and sql server db :) let me know what you've go so far

SOAP is a protocol, Simple Object Access Protocol, SOAP uses HTTP as a transport layer, you can use soap with other protocols. Right now, is used to instance web services (an application as a service). The idea with SOAP is to access an object methods remotly. You can download the SOAP specifications in www.w3.org/TR/soap/

REST refers to REpresentational State Transfer. It is a set of architectural principle relating to a simple, stateless, entity-oriented interface to information with a well defined set of operations. ie. that which has driven the growth of the web.\n\nREST style Web Services is kind of an oxymoron, since Web Services usually refer to SOAP over HTTP, which are bloated and not really RESTful.\n\nSee source for more info.

Because:\nThe applications on a server (a type of webpage/site) carry out some actions before sending a result to you ...\n\nExample : When you post a question to Y! Answers. The server's job is to list it for others to see and act upon.\n\nServer is basically very much like your computer. But servers are solely dedicated to a website i.e. all their resources are used to handle large amounts of visitors and their requests...\n\nYou can use your PC as a small-scale server too ...\n\nJust like building webpages is called "web-designing", coding a servers actions is called "server-scripting"...\n\nMany Languages are used for server-scripting. Ex- PHP, ASP, etc.\n\nHope this helps...

A web server is like a library. You ask for a book and you get the same book every time. An application server is like a bank, you ask for your account balance, and it might be different each time you ask. You can also ask to have your balanced changed (by depositing or withdrawning money).\n\nAll web application servers are web servers. They can service requests for static files, like a library. They can also service transaction requests, like a bank. Not all transactions are about money, by the way. Yahoo Answers is an application server that is processing your request to post a question and my request to post an answer; these are transactions because the state of the information on the server changes after each request. It is possible to have an application server that is not a web server, for example multiplayer online games are often implemented with servers.\n\nTomcat is a good application server to work with when you are starting out. WebSphere costs money to run, at least commerically, but it comes with some customer support. Struts is a component that can be installed in a java web application server that makes writing database based application servers easier. It is essentially some source code that you can use so you don't have to write the whole thing yourself.

AJAX uses a bit of javascript that uses the XmlHTTP object.  This object, opens up a connection to a Web server, transmits and receives data, then calls back the javascript on the page which was used to invoke it.\n\nWhat this means is that changes on the client side can communicate with the server, then dynamically update the client user interface without having to request a new Web page from the server.\n\nWhile this slightly complicates developing Web applications that use AJAX technologies (which, by the way, is just a name given to the various technologies employed to use this methodology), it makes for a very smooth user experience since they are not constantly refreshing Web pages.\n\nAJAX applications give an appearance of a 'thick client' application while still being a 'thin client' (i.e. application that runs in a Web browser.)  However, it is important to note that network communication is still going on in the background while the application is being used.

SOA is the service oriented architecture, it implies that all your functionality is offered through services.\n\nThe BPEL is for business processes, you can manage your business processes by the mean of services offered by your software.

What service are you talking about?\n\nWe can't help you if we don't know what website or web service you are using.

Web services came in to picture because the companies are now trying to to be more and more cooperative in all the respects.so the application that are developed using different technologies can communicate with each other.The applications communicate with each other using the XML.If one wants to expose the part of the application as the webservice just register with the UDDI,From where the client applications makes the look up and invokes the applications.The protocol that is basically used is the Soap/Http.The client looks up to the UDDI and from where he is routed to the WSDL page which contains the information about the service the type of binding the port on which it is exposed etc,and finally the service gets invoked.There are several lot of things that needs to be taken care from the webservices prospective like maintaining the state of the user in the complex webservices the implementation of the security features etc.

Since this is your first application i would probably recommend starting with ASP.NET and C#.  It's relatively easy to learn and implement and web project within the dot net framework.   However, I do like the control and features that server side Java (JSP,Servlets,JSF,etc...) programming allows.  The down side do java is that deploying the application once it's written is somewhat cumbersome.   There's also PHP.. which i personally hate! with a passion.. but is very similar to ASP.\n\nEitherway whichever technology you use, there are plenty of example and tutorials online that can guide you through getting started.   \n\nHope this helps....

This is typically used to store the CGI programs (say in Perl) which are server side scripts. \nServer Side Scripts are code snippets that are executed from inside a webserver to create a web page at run time.
