WEB SERVICES

In the last days we have had a number of threads on web services, plus a number of OSS messages. It seems that this topic is just ready for prime time. I discussed this with our inhouse expert, and his answer was that, starting with WebAS 6.40, one should not mess around with low level HTTP access. There is a complete proxy generation workbench available, that will encapsulate the webservice into normal classes. A small demo was very impressive.

Today I decided to again read up on the two weblogs from Thomas. Let us just face facts: these two weblogs already describe in high detail everything that is needed to start in WebAS 6.40. Later one can check into the online documentation. These two articles are <b>required</b> reading for anyone asking questions on webservices!

@Thomas: well written! PS: For my light cooking, I have installed an fire alarm in the kitchen. It has saved my bacon (literally) once.

For those of you who are interested in WebServices and who may have liked these weblogs, I thought I might mention (at the risk of a little self-promotion) that I will be

presenting on this topic both at the SDN Meets Labs Palo Alto and at the ASUG spring conference. The two presentations will be slightly difference in focus, but both will cover my company's real world experience with WebServices.

In fact I am in Europe this week implementing a dozen or so new critial WebServices for Input and Output to/from our R/3 system. So I should have plenty to share about my

experiences both at these presentations and in future weblogs. I promise to give the good, the bad, and the ugly.

It is good to see the explosion in interest in WebServices and I expect to see many more SDN members sharing their experieneces as weblogs in the future.

Hallo Thomas,

As you mentioned before, it is not redirectly BSP related, but to tell the truth, it is a very hot topic for this community, and I am very interested. It is exactly these "real world experiences" that allows one to finally decide whether something is going to stand the test of time, and where one has to invest more. These stories beat any form of technical discussions any day. Any thing you should write on this (as well as other people's experiences) are definitely on my reading list!

bye, brian

Thomas, I hope that you'll do the presentation at SDN Meets Labs in Walldorf too.

I'm afraid not. It was difficult enough to convince my management just to let me go out to the West Coast. Between the one SDN Meets in the United States, ASUG (America's SAP User Group), and TechED; my travel budget will be pushed to the limit and beyond this year.

FYI... I've posted a weblog with many of the experiences with WebServices that I described earlier.

WebServices: A real world implementation experience

/people/thomas.jung3/blog/2005/02/14/webservices-a-real-world-implementation-experience

In this weblog I attempt to caputre the experiences of the last few weeks, as my company went live with several new WebService Interfaces.

Thomas,

Absolutely terrific information in the three weblogs I've read from you about Developing ABAP Webservices. What I haven't found yet is wether or not a method can be exposed as a web service?

Thanks,

Anthony

I will have to play in my 640 system tomorrow to see if there is an option to build a virtual interface around an ABAP OO class. However in 620 everything revolves around RFCs. I am sure this has something to do with the fact that SAP has never really extended their Remote functionality to ABAP OO.

That's something I don't really understand. They have tremendous and easy to use functionality in the RFC. They have a nice OO implementation. Why the two have never been brought together I don't understand.
