I have been told he is the Web Services god in Delphi. Here is my problem. I am having a very difficult time comprehending the concept behind a web service. My boss asked me to: 1) Create a "service" that will read in a series of PDF file names (from a folder). 2) Compare the file names with the file names listed in a database 3) Take the PDF files and print them automatically using the syntax that you can pass to Adobe Acrobat (the printer information is understood because it's listed for each PDF file in the database). THAT part is no problem... BUT.. He said he also wanted me to create a CLIENT control in which different LABS could monitor the PDF files, and control the printing manually. He said he wanted me to have Delphi contact the Client through webpages using SOAP. I'm under the impression that I have to use a WebService to do this. I am completely at a loss. Everywhere I look to create a Web Service, it asks me for one that already exists.. I thought hte point was that I was supposed to create my own Web Service? Can anyone tell me, what exactly a Web Service is... how do I create one, what am I doing? ALL my experience in Delphi has been solely to create Database Applications.. I've used XML on numerous occasions, and I understand that SOAP is XML, but basically with standard tag lines. ANY help is appreciated. I went to Matlus.com and that helped some, but it only brings up more questions for which I don't even know how to ask? Thanks!

You can find them both at www.remobjects.com and if you purchase their awesome frameworks (Remote Objects, Data Abstract) you'll probably be promoted to CEO in your company. See you on the RO/DA newsgroups soon ! :-) JoeH Back to top mamcx Guest Posted: Thu May 27, 2004 8:05 pm    Post subject: Re: WebServices and Alessandro Federici Quote: Hey guys, I'm looking for someone named Alessandro Federici. Must be bussy with your own company, www.remobjects.com Quote: Here is my problem. I am having a very difficult time comprehending the concept behind a web service. A web service, is simply: A class exposed with a discovery language(WSDL), standarized with the name of SOAP, and marshall data using XML. In other words, is put: function HelloDude():String begin ... ... end; In something like (NO THE REAL REPRESENTATION) <A Soap function Id=HelloDude ReturnValue=String> So any client can read it and execute it. In the website www.remobjects.com exist good articles. Plus, search bdn.borland.com, exist material about it However, you can use plain delphi for the task too. Quote: THAT part is no problem... BUT.. He said he also wanted me to create a CLIENT control in which different LABS could monitor the PDF files, and control the printing manually. He said he wanted me to have Delphi contact the Client through webpages using SOAP. He, is a manager or really know ??? ;) Quote: I'm under the impression that I have to use a WebService to do this.

Can anyone tell me, what exactly a Web Service is... how do I create one, what am I doing? A web service can be a way, not the only way. By fortune, with Delphi is not so hard. The only tricky part can be return the file using the webservice, but if you only need list things and return simply values is very simply.

Is the same tricks with new names... Don't worry so much. If you have past experiences with COM, MIDAS, DataSnap, or anny midle-tier then the thing is similar...

I went to Matlus.com and that helped some, but it only brings up more questions for which I don't even know how to ask? Well, first of all, a bit of definitions: a "Service" is fundamentally a set of procedures/functions that can be remotely invoked by a client application. The emphasis these days is on the "Web" part which basically means a service accessible remotely over HTTP using SOAP as messaging protocol. HTTP gets you to *where* the service is, the XML that defines the SOAP message tells the service *what* to do. I am intentionally over-simplifying this just to give you an idea. HTTP is only one of the many possible protocols you can use to exchange SOAP messages. Take a look at http://www.soapuser.com/basics1.html for more in depth (but still simple) information. I once had another link to a site that explained SOAP in like 5 minutes, but I cannot find it now. The link above seems good anyways. You might also want to read more about SOA (Service Oriented Architecture). Some interesting starting material can be found at: http://www.service-architecture.com/web-services/articles/service-oriented_architecture_soa_definition.html http://www.ondotnet.com/pub/a/dotnet/2003/08/18/soa_explained.html and more by simply querying Google with a: http://www.google.com/search?hl=en&ie=UTF-8&q=soa+service+oriented Anyhow, the "how to create one" solely depends on the framework you're using. If you use Delphi 5+, you could use our product, the RemObjects SDK, as explained by Bob Swart at http://www.drbob42.com/review/index.htm We also have tutorials on our web site at www.remobjects.com You might want to read what's in the introductory articles: http://www.remobjects.com?RO01 (Introduction to the SDK) http://www.remobjects.com?RO04 (Article that explains what our MegaDemo sample does) http://www.remobjects.com?RO05 (First Steps - How to Write a RemObjects Server) http://www.remobjects.com?RO06 (First Steps - How to Write a RemObjects Client) and later move to those related to Smart Services: http://www.remobjects.com?RO07 http://www.remobjects.com?RO08 The RO07 article provides a good explanation of what Smart Services are and why you want to use them versus only using the limited SOAP Web Services. I hope the links above helped you somehow.
