JScript .NET, Part VI: Creating IE Web Services

In this column we continue our series on JScript .NET. In Part I, we laid down the groundwork for JScript .NET, showing you how to install IIS and the .NET SDK, and how to compile and run a JScript .NET program. In Part II, we showed you the major differences between JavaScript and JScript .NET. In Part III, we focused on JScript .NET's classes and their division among namespaces. In Part IV we taught you how to use inheritance in classes and interfaces. In Part V, we covered the third holy grail of object oriented programming: polymorphism. In this column, we'll show you how to define Web services in JScript .NET and how to consume them.

In our previous 11-part series on Web services, Columns 96 to 106, we showed you how to consume Web services on other domains. In the current series, we've covered the subject of JScript .NET. You can use JScript .NET to define your own Web services and install them on your IIS Web server. In this column, we'll show you how to combine what you have learned from the Web service series with what you have learned from the JScript .NET series. We'll teach you how to define and consume Web services. We'll use two examples: add and IsPrime.

Unzip the attached file and put the two included asmx files in a new directory: c:\inetpub\wwwroot\Webreference. Put the files example.html and webservice.htc in a separate directory anywhere on your hard drive, and then load example.html in your browser. For example, if you placed the example.html and webservice.htc files in the directory c:\docjs, then you would load the example by typing this URL into your browser: c:\docjs\example.html. Try both Web services and see that you get correct answers.

These Web service examples work properly in Internet Explorer browsers, version 5.5 or later. You also need to have the IIS Web server installed, as well as the .NET SDK. Well, hopefully you have them by now; otherwise you have missed out on some great stuff in our current series on JScript .NET. See Column 107 for details.

In this column you will learn:

• How to create a Web service
• How to interact with the add Web service
• How to interact with the IsPrime Web service
• How to write a GUI for consuming the add and IsPrime Web services
• How to script a page that consumes the add and IsPrime Web services from IE

The following files were zipped for you: checkIsPrime.asmx (the IsPrime Web service), simpleCalc.asmx (the add Web service), add.html (a consumer of the add Web service), isprime.html (a consumer of the IsPrime Web service), example.html (a consumer of both services) and webservice.htc (the DHTML behavior).
