My iPhone now runs the new version 1.1.4. IPSF still works! Here’s what I did:

• Downloaded ZiPhone 2.5.
  • If you’re runningVista, make sure you run the executable with administrator permissions

You’re looking for a way to consume Web services in SAP NetWeaver 2004s (and SAP Composition Environment aka NetWeaver 7.1) from BEA WebLogic Server 8.1 (and newer versions) using Single Sign On (SSO)?

You may have figured out already that SAML is not an option here because the SAP side is just a SAML consumer and not a provider (as of today). The only way left is to use the proprietary SAP Logon Tickets. Proprietary authentication mechanisms always require some extra work. In this blog article I’ll fill you in on what you need to SSO-connect those two J2EE platforms. Read more »

Geotagging photos is becoming more and more popular since photosharing websites like Flickr, Picasa Web Albums and others support close integration of geotagged EXIF information.

Added 2008-7-13: See here for a complete geotagging workflow on the Mac!

Manual geotagging is a slow and boring process - provided you remember the locations the photos were taken at. I’m convinced that it won’t take long until almost every cheapo digital camera comes with its own GPS receiver that automatically stamps the coordinates into the EXIF header but unfortunately, we’re not quite there yet. So the main question is: how do I get the GPS readings into the EXIF header of the photos in my Nikon D80? Read more »

It’s not a secret that these days most server hacking attempts originate from chinese IP addresses. A lot of attempts originate from other countries like South Korea and Indonesia as well. It seems that in those countries (cyber-)law-enforcement and technological advancement don’t correlate. I agree that a server has to be able to sustain non-flooding attacks just by using a proper and secure server configuration. But what if almost all traffic from those countries are automated vulnerability scans? Read more »

To validate/verify a SAP Logon Ticket in a non-SAP Java environment you have to call into native libraries. Fortunately there’s some Java sample code provided in the SAPSSOEXT library archive.

Go to service.sap.com (you need a valid user and download permissions) -> Download -> Support Packages and Patches -> Entry by Application Group -> Additional Components, follow the SAPSECULIB and SAPSSOEXT links and download the library versions for your operating system. You’ll also need SAPCAR to extract those .SAR files. Both libraries - sapsecu.dll and sapssoext.dll - are needed to validate a SAP Logon Ticket. Read more »
