REST-orientation: Controlling access to resources
Exposing data and functions from SAP in a Resource Orientated Architecture (ROA) approach (i.e. following REST principles) is extremely powerful. But that power must be matched with control. In this weblog post, I explain how I achieve the right level of granular access control for the resources served by my new REST handler/dispatcher for the ICF.  Sep. 30, 2009

A new REST handler / dispatcher for the ICF
In implementing a REST-orientated HTTP-based application in SAP, I found myself wanting something slightly different from what the ICF framework offered me in terms of handling and dispatching requests. So I built it. Sep. 21, 2009

OssNoteFix script updated for Greasemonkey 0.6.4 and Firefox 1.5
I've finally got around to updating the OssNoteFix Greasemonkey script (which makes using OSS notes on the web less painful). So all those of you who upgraded your Firefox browser to 1.5 can have some OssNoteFix love again.  Feb. 7, 2006

Hacking the SAP service portal to make OSS notes better
I finally put my money where my mouth was and did something to improve the OSS note experience on SAP's service portal to make the pages more web- and developer-friendly. I wrote a Greasemonkey script for Firefox that makes each OSS note page more useful. May. 20, 2005

SAP TechEd here I come ... with session slides!
Looking forward to SAP TechEd in Munich this year. This is a post about TechEd and my talk that I'm "hand-aggregating" into SDN from my own weblog. (I've been having trouble getting into and using SDN recently - it doesn't work any more in my browser - so I've been posting elsewhere.) Oct. 1, 2004

Forget SOAP - build real web services with the ICF
As a followup to my recent article "Real Web Services with REST and ICF" (linked from the SDN homepage right now under "Don't use SOAP"), I show in this weblog entry how straightforward and natural integration of SAP data can be with a REST approach, using an extended spreadsheet function as an example.  Jun. 24, 2004

NW4, OSS1 and logon group selection for OSS
When using transaction OSS1 to build a connection to OSS, you normally get a popup presenting a list of groups that you can select from to log on. With my new Linux-based NetWeaver '04 demo system NW4 this wasn't happening. I spent a bit of time finding out what this was all about, and why it doesn't work in NW4.  May. 31, 2004

SAP at JAX 2004
Looks like there were a number of SAP-related sessions at this year's Jax 2004. With the SAP world continuously opening up, it's great to see more and more collaboration and cooperation with open source and other collectives. May. 11, 2004

WAS 6.40 testdrive for Linux is here!

Food for thought: LDBs and ABAP Objects
In a TechEd session last month on ABAP Objects, I came across a wonderful example of an LDB implemented using methods and events. While the re-implementation of the classic PUT/GET relationship is just an example to illustrate ABAP Objects' explicitness, it nevertheless is a thing of beauty. Nov. 13, 2003

BSP: Mangled URL Decoder
Brian gave us a great rundown of URL mangling by the BSP engine, and mentioned the 'decode_url' BSP application which showed you what the gunk in the rewritten URL means. 'decode_url' isn't in my (Linux-based) WAS 6.10 system (and therefore perhaps not in yours either) so I hacked one up as curiosity got the better of me. Oct. 17, 2003
