Announcing WS4D-JCoAP

April 14th, 2011

WS4D JCoAP WS4D-jCoAP is an implementation of the Constrained Application Protocol (CoAP) for Java. CoAP is an exciting emerging protocol defined by the IETF CoRE WG, which is a RFC – Proposed Standard. To put things short, CoAP is supposed to create an alternative to HTTP for RESTful APIs on highly resource-constrained devices. While HTTP usually bases on TCP, CoAP defines rudimentary reliability features so you can run it on UDP and therefore save a lot of protocol overhead that inherently comes with TCP.

Now that you have an idea of what CoAP is (if you hadn’t already) we want to share our latest efforts on implementing CoAP. Until now WS4D-jCoAP has grown to be a complete CoAP draft 18 implementation of the client and server side and it is still evolving.

If you are curious right now or want to support us, check out the gitlab repository. Have fun!

Meet WS4D @ embedded world 2010 in Nürnberg

February 24th, 2010

The University of Rostock exhibits on the embedded world in Nürnberg (02.03. – 04.03.2010) and promotes WS4D technologies to overcome the problems of the heterogeneous hardware structure with advanced cross domain solutions. See the “Internet of Things” and make your first experiences with WS4D. We will present you:

  • A complete overview about the WS4D technologies and its potentials for the creation of smart cross domain systems.
  • Advanced software toolkits for WS4D development with C/C++ and Java.
  • The WS4D-PipesBox tool for the easy graphical creation of device ensembles and service mashups.  

We will demonstrate the power and  simplicity of WS4D in the domain of Home Automation (Smart Objects, digitalStrom).

Miscellaneous contacts already have been established and hopefully more potentials partners from industry and for research will follow during the following days. Come and see the live demonstration of the WS4D capabilities and meet the team. Visit us at Hall 11, 11-128 with the exhibit “WS4D – Web Services for Devices – Cross domain technology for smart systems.

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.
