Reprints of the following articles are no longer available from Pinnacle Publishing nor can the code be downloaded therefore we have provided scanned and Microsoft Word versions of these articles, plus the code for the author's articles.

	Connecting Web Services, October 2001, XML Developer (VB 6 Server with Clients: VB 6, JScript/ ASP, VBScript/ ASP, Perl.) PDF (5.0 Mb), Word (53 Kb) Summary: Implementing Web Services in different languages (and platforms) is not very difficult, as long as you have some familiarity with the particular language, the platform, as well as at least a general knowledge of XML and SOAP. However, making sure that the different systems can connect to each other can be a bit more challenging. I will cover few different scenarios of systems based in different language platforms and object models and show you how they can be brought to talk to each other. I'll start with Visual Basic and the scripting languages: JScript, VBScript, and PERL. In the months to come we'll continue the same exercise with other language and platform combinations.
	Connecting Web Services, December 2001, XML Developer (IBM/Java Server with Microsoft/ VBScript Client) PDF (5.4 Mb), Word (54 Kb) Summary: Last month, I showed you how to create a Web Service with Visual Basic and then call it using the scripting languages: JScript, VBScript, and PERL. This month, I'll create the same Web Service in Java, using the IBM Web Services Toolkit, and then I will call it from VBScript. Keep in mind that implementing Web Services in different languages (and platforms) is not very difficult, as long as you have some familiarity with the particular language, the platform, as well some knowledge of XML and SOAP. However, making sure that the different systems can connect to each other can be a bit more challenging. I'll look into some of these interoperability challenges, particularly as it relates to using VBScript to call a Java based Web Service.
	Connecting Web Services, January 2002, XML Developer (Perl Server with Java Client) PDF (5.1 Mb), Word (54 Kb) Summary: A couple of months ago, I showed you how to create a Web Service with Visual Basic and then call it using the scripting languages: JScript, VBScript, and PERL. Last month, I created the same Web Service in Java, using the IBM Web Services Toolkit, and then I called it from VBScript. This month I will work on another combination of languages: I'll create the Web Service in PERL and then call it from Java. As I have said in the past, implementing Web Services in different languages (and platforms) is not very difficult, as long as you have some familiarity with the particular language, the platform, as well some knowledge of XML and SOAP. However, making sure that the different systems can connect to each other can be a bit more challenging. I'll continue looking into some of these interoperability difficulties, particularly as it relates to PERL and Java based Web Service.
	Connecting Web Services, February 2002, XML Developer (C++/ Systinet (Idoox) Server to ASP/ VBScript Client) PDF 4.5 Mb), Word (64 Kb) Summary: This month, Zoran Zaev builds a Web Service in C++ using Systinet's WASP for C++ (formerly known as IdooXoap for C++), and then he calls it from ASP/VBScript. This article shows the kind of issues that you can run into as you work on implementing Web Services in C++, using WSDL with C++, and calling this implementation from an environment such as ASP.
	Securing Web Services, June 2002, XML Developer (VB 6.0 and MS SOAP Toolkit 2.0) PDF (5.1 Mb), Word (53 Kb) Summary: This month, Zoran Zaev shows you how to secure your web services by implementing transport level authentication with Visual Basic. Then, he calls the web services from Visual Basic, VBScript/ASP, and PERL. Finally, he implements transport level SSL encryption to the web services used in his examples.
	Securing Web Services, July 2002, XML Developer (Visual Basic.NET) PDF (3.6 Mb), Word (138 Kb) Summary: This month, Zoran Zaev shows you how to secure your Web Services by implementing transport level authentication over SSL with Visual Basic.NET. Then, he calls the Web Services from Visual Basic.NET windows form.
