-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cooper, Rudy Sent: 11 March 2005 21:00 To: u2-users@listserver.u2ug.org Subject: [U2] [UV] Web Services for Dummies Has anyone developed a web service for Universe ? Yes, I used Delphi to create an ISAPI DLL (a DLL that interfaces directly into Internet Information Server). This uses the regular Microsoft XML parser to generate and interpret SOAP and XML RPC requests and a UniObjects pool to make calls to BASIC subroutines. The key things are: I map each subroutine argument to a named type. These can be simple (string, date, integer etc) or complex types made up of simple types e.g. an Order Header, in which case each type element is mapped to field in the subroutine parameter. Repeatable types, like order lines, are mapped multivalued. The gateway DLL generates WSDL (Web Service Definition Language) to describe each subroutine that has been mapped in this way. This means that tools like Delphi and .Net can automatically generate class definitions based on the types I have defined, and the code to call the web service. I started off parsing the XML on the server, but found that there were just too many variations on the SOAP/XML formats to cater for all of them in a BASIC parser - it became too slow and top heavy. So I moved everything to the web server and it works fine. If you want to know more, contact me off line.

RE: [U2] [UV] Web Services for Dummies
This one has come up again and again over the last few weeks. You'll find lots of posting about it on www.indexinfocus.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cooper, Rudy Sent: 11 March 2005 21:00 To: u2-users@listserver.u2ug.org Subject: [U2] [UV] Web Services for Dummies Has anyone developed a web service for Universe ? I'm trying to gather as much info as I can about the technology used. I realize UV 10.1 has many of the tools that I'll need for the backend, but what is normally used on the frontend, what communications protocal is normally used ? I've read alot of theory about how it should work, but I haven't come across anything that gives me some concrete examples. Can someone direct me to some information or maybe explain to me in practical terms on how an xml request would come into UV then a response sent back to the requestor from UV using xml. If you've done web services using ASP.NET and UV I would appreciate hearing from you. thx. rudy Rudy Cooper Sage Publications I.T Development Thousand Oaks, California (805) 499-0721 #7724 --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/ The information contained in this email is strictly confidential and for the use of the addressee only, unless otherwise indicated.

RE: [U2] [UV] Web Services for Dummies
Please see my four articles on Web Services and .NET, originally printed in Spectrum Magazine from 2003-2004. Magazines are here: http://www.intl-spectrum.com/SPECTRUMMAG.HTML HTML versions here: http://../articles/ I also have an article there called SOAP for people who don't do protocols which is a follow-up to my What are Sockets? article. In particular, Universe doesn't really play a part in Web Services per-se, unless you use socket coding to make it into a socket client and/or server. I'd recommend against that approach. To make Universe a web service client: - Use mainstream tools like .NET, J2EE, or Perl to create a WS client to an external service of your choice. Web Service sources publish WSDL which identifies the API to their service. Mainstream tools easily create WS clients to conform to the server side. - Then create a pipe from your new WS client into U2, to function purely as a data transport. For this you can use UO, UO.NET, MV.NET, PDP.NET, RedBack, or other tools described in this forum recently. To publish U2 business rules as a web service, follow the same pattern: - Use mainstream tools to publish WSDL and accept inbound WS requests. - When requests come in, connect to U2 to run BASIC programs, run rules, and build a result set. - The data from U2 can be built into XML, ready to be passed out through the Web Service, or you can pass back simple data and let your Web Service wrap it properly prior to returning data back to the client. I've written Web Services to/from MV platforms using .NET and Perl (not together), and am prepared to develop end-to-end solutions for VARs or end-users. I hope that helps.

Here is a direct link to the last one of the four articles that Tony is referring to. This will open as a pdf inside your browser, takes about 20 seconds on a T1 connection to open it. http://www.intl-spectrum.com/publications/JulAug04.pdf Will -Original Message- From: Tony Gravagno [EMAIL PROTECTED] To: u2-users@listserver.u2ug.org Sent: Fri, 11 Mar 2005 14:59:42 -0800 Subject: RE: [U2] [UV] Web Services for Dummies Please see my four articles on Web Services and .NET, originally printed in Spectrum Magazine from 2003-2004.
