Whether or not we are experts in our respective trades, learning from examples is usually the quickest way to learn skills that can improve our work performance. In Web services, learning its ins and outs can be achieved by looking at Web services examples that are made by experts. It can also help to know that regardless of the programming language used, Web services can be created.
Newbies who are still improving or developing their Web services skills should know what to look for in Web services examples in order to understand how they work. To break down the basic details, the architecture of a Web service usually has two components. The first component is the service provider, which applies the web service in order to make it available across the intranet or Internet. The second component is the service requestor, which opens a network connection in order to send an XML request by using an existing web service. Note that a Web service component can be found in any application.
Web services examples usually use a standard template that shows a service provider and Web services that applications use. But, how will you know that they really work? The only way to test them is by stopping the Web server to keep the application from contacting the Web service. Then, run the application during which you should expect a run-time exception. After which, you need to start the Web server. During testing, the examples are published on an intranet or over the Internet in order to check whether or not they work.
Learning from Web services examples that are either created from web tutorials or from an office mentor, helps learners apply the theories they have learned. It is also a way of enhancing their learning because they can immediately receive feedback or see the results for themselves. The setup helps them correct their mistakes while the correct theories are still fresh in their heads. The presence of mentors during the learning process is even more advantageous because learners can immediately ask questions and receive answers. Note that learners who are able to interact with mentors during their learning process gain a lot from examples.
