Nach unser Sommerpause treffen wir uns am Mittwoch, den 19.08.09 wieder. Der Ort ist altbekannt (kommt aber unten noch mal), diesmal begrüßen wir einen Gast aus Dänemark. Inhalt etc. zum Vortrag und zur Person kommen direkt aus Dänemark und liegen in englischer Sprache vor. Wir hoffen, dass dies nicht all zu abschreckend ist ;-)

Da Preben von der Firma TriFork freigestellt wird, die u.a. die dänische Java-Konferenz JAOO ausrichtet, findet ihr hier auch noch ein paar Informationen dazu.

Talk : System Integration and webservices with REST

For several years we have based our web services on SOAP blinded by the illusion that this approach would give interoperability and that WSDL is a unique web service description and therefore an easy approach to automatic code generation - but this is, in fact, far from the truth.

What works on .Net 1.1 fails on .Net 3.0 and different versions of Xerces, WebLogic , and WebSphere parse the WSDL file in different ways.

Ironically, the WSDL file has two goals: Allowing automatic code generation and being human readable. But also the human readable part fails - only a few really know how endpoints, bindings, service names, and methods map to the code. On top of that, the SOAP stack is a black box and when it fails in production, we don't know where to start.

REST-services have a far more pragmatic approach to things and there is no problem in doing system-system communication using REST services.

Experience tells us that exposing data the REST way not only solves the problem at hand - the service consumers invent new ways of combining data and new and exciting applications and clients appear.

During the speech we will take a further look at REST services with focus on Java implementations.

View Larger Map

Wenn ihr so wie in der Map steht, befindet ihr euch zwischen dem Neubau des Campus und dem Bau für Maschinenbau. Um zum Informatikum zu gelangen, geht ihr zwischen den Gebäuden durch, dann kommt ihr direkt darauf zu (liegt hinter dem AStA). Vierter Stock, Raum 405, viel Spaß ;o)
Also dann, auf einen spannenden Vortrag am Mittwoch, den 19.08.2009 & viele Grüße,
Björn, Daniel & Dirk
