Subject: WebTech THURS 4/19 Sun Burlington - Web Services

Hi everybody, and happy Spring at last!

This month's meeting will be a joint meeting with NEJUG, being held at
Sun Microsystems' Burlington facility on THURSDAY April 19th, starting
at 6:00pm.  Please note the different day and location.

Details and directions are available at both at the WebTech website
http://www.acm.org/chapters/webtech, and at the NEJUG site, which is
http://www.nejug.org/2001/apr01.html.

This will probably be a very full meeting, so please register if you plan
to attend, at http://www.nejug.org/2001/apr01.html.  NEJUG's sponsors
will provide pizza and beverages for all attendees.

This month's presentation will be by Mark Colan from IBM Corporation
on "Web Services (SOAP, UDDI, and WSDL)."  This is an important, hot
topic, and Mark is sure to deliver an excellent presentation as has done so
consistently in the past.  Don't miss it!

Abstract

           SOAP is ushering in a new model of using the Web. Instead of
           browsing a web of linked documents and manually initiating
           requests by forms, SOAP allows us to access Web Services
           directly, by invoking method calls on remote objects using an
           XML message, and receiving an XML response document. SOAP
           might have been called "Services-Oriented Architecture
           Protocol", since it has moved forward from its roots as a Simple
           Object Access Protocol.

           But how do we find the services we want to access? UDDI, for
           Universal Description, Discovery, and Integration, allows
           protocols like SOAP to be used to find required services, and
           operational information necessary to bind to and use a service.
           UDDI will use an XML language like WSDL to describe services
           and service providers. "Web Services" is the result of combining
           SOAP, UDDI, and WSDL to create a foundation for e-business.

           This talk presents the latest information on Web Services
           technologies. It includes a brief look at IBM's Web Services
           Toolkit (available for free download from ibm.com/alphaworks),
           and demonstrations that show how the technologies work.
