You might say now, OK, all fine and dandy in theory, by why use headers? Why not just send everything in the SOAP Body? The next picture offers a visual representation of the SOAP message. The structure of the SOAP Fault (yes, this too has a structure) is not important for our talk, but you can find it here.Īs explained above the SOAP Header and the SOAP Fault are optional. The SOAP Body contains the actual message payload or a SOAP Fault element in case an error occurred on the caller side. The header(s) is an optional part of every SOAP message.Ī SOAP message is composed of a so-called SOAP Envelope which in turn contains: Well, search no more because your responses lie in this 2 “H”: Headers and Handlers. I am getting there…now.ĭid you ever think: “I would really like to see the SOAP message that I get before it is passed to the top level service and IS does its magic…” or “I wish I could ask the client application to sent me also some metadata regarding the message”.
Sure there will be some corner or more exceptional cases where you will need to do more than just click “Next” through some screens, but for the majority of the use cases, the defaults will suit you just fine.īy now you are thinking: “This guy wants to put everything in context.or what?”. Well, before we go to the good stuff, let me just say it once again: It is super easy to work with web services in IS.
The same remark is valid for creating Web Service Consumers (WSC) out of the provider WSDL.īut you might say, where is the exploring part? Or are you writing this post just to preach how easy it is to work with web services in IS? Now as easy it is to work with web services in Java, for example, it is super easy to work with them in Integration Server(IS).Īssuming that you already have the services that you want to expose as web services, it takes somewhere around 20-30 seconds (depending on how fast you click and what options you want to be changed) to have a fully functional web service endpoint deployed on your IS. Web services are not biased to a certain language or family of languages or language types (statically vs. It is now easy to create web service providers in one language and consume them in an application written in another language. In the meantime (i.e the last 15 years) web services got a lot of traction and were adopted by the majority of the programming languages.
The 3 major concepts from the initial specification are WSDL (Web Services Description Language), SOAP (Simple Object Access Protocol) and UDDI (Universal Description, Discovery, and Integration).The standardization of the web services started in 2002 by W3C.So, before we dive into the serious stuff, let’s check some interesting web services trivia: Obviously, they haven’t been around as long as Christmas but I bet that you have to spend some time trying to remember when you first used web services. The Christmas holidays (if you are celebrating) are just over so I thought it would be a good idea to talk about something that has also been around for a long time: web services. Hello everybody and welcome to a new round of exploring.
