Back from OASIS WS-DD interop and face-to-face meeting

January 6th, 2009

After joining the WS-DD Technical Comitee at OASIS Ingo Lück (University of Dortmund) and Elmar Zeeb (University of Rostock) attended the WS-DD interop and face-to-face meeting that was hosted by Software AG in San Jose, CA from 8th to 11th of December.

We were able to test our WS4D-JavaMe and WS4D-gSOAP toolkits for interoperability with several implementations from Microsoft and printer vendors that are part of the WS-DD TC. More detailed Information from the WS-DD TC about the interoperability tests will be available soon.

Furthermore we were able to participate in the standardization process and contribute our knowledge and proposals for the devices profile for web services (DPWS) to the WS-DD TC.

The TC has established a firm timeline for the production of WS-DD v1.1 specifications that will be an official OASIS Standard as of June 1, 2009. The WS-DD TC is going to standardize the SOAP-over-UDP, WS-Discovery and DPWS specification. See the WS-DD TC site for more information.

Introduction to DPWS technology made simple with JMEDS

September 24th, 2008

If you are unfamiliar with DPWS-based applications, then the packages ws4d-explorer* and ws4d-javame-examples of our SourceForge project pages are the right places to start with: Download a current version of the DPWS Explorer, start it and then download an example application. When you start the application, it should be displayed in the DPWS Explorer. You can now browse through the device and service information of the application and call some actions to understand the basics of the SOA-based DPWS technology.

When you get interested, check out the ws4d-javame-documentation package for some example code snippets of simple DPWS applications. If you get the idea go to package ws4d-javame-full, download the stack for JAVA SE (ws4d-javame.stack.SE.jar) or JAVA CLDC (ws4d-javame.stack.CLDC.jar) and start developing your own DPWS-based applications.

JavaME Stack is now OpenSource

November 10th, 2007

Today we have released the WS4D JavaME stack on SourceForge. The release includes JAR files and source code available through download or the subversion repository. Have fun!

DPWS Explorer goes online

October 10th, 2007

Today WS4D is introducing the first tool for exploring DPWS-enabled network devices. The DPWS Explorer is a GUI-based analyzing tool for DPWS devices, services and messages. It is a client implementation based on the WS4D Java Multi Edition DPWS Stack. E.g. the DPWS Explorer allows to view metadata information of discovered devices and services, to call actions of this services, see its responses, view the DPWS messages exchanged between the Explorer and other DPWS entities. The DPWS Explorer is developed cooperatively by MATERNA and University of Dortmund. Download the actual version here.
