The current implementation of the integration of our java multi edition stack (JMEDS) into OSGi was now released as v0.0.1 and can be downloaded here. It can be used to distribute the services of an OSGi plattform, use OSGi services with DPWS clients and integrate DPWS devices into OSGi. As usual, feedback like suggestions or bug reports are always highly appreciated (Please feel free to use the trackers and forums located on our sourceforge project page).

We are back  from the OASIS WS-DD interop / face-to-face meeting and the CeBIT IT exhibition in Hannover.

During the WS-DD meetings (23.-26.2. hosted by Canon at their Santa Ana, CA campus) we tested the security part of DPWS with our ws4d-gsoap toolkit. The changes will be part of a new release described later. During the face-to-face we continued the standardization work to accomplish the version 1.1 of DPWS, WS-Discovery and SOAP-over-UDP specifications until June. As you can see on the issue list, most issues are solved. So the deadline at June looks good.

During the CeBIT exhibition in Hannover we introduced our new and easy to use composition tool to create new applications in device scenarios. This time our main focus was the health care scenario. Our compositione tool called pipes attracted a lot of attention. We plan to release this tool as open source soon, so you can connect your DPWS capable devices with each other, with regular web services, web 2.0 services or even other devices that don’t support DPWS!

Apart from that we look for new application domains of DPWS. One such new application domain is distributed OSGi. So we are developing an integration of our java multi edition stack (JMEDS) into OSGi. It can be used to distribute the services of an OSGi plattform, use OSGi services with DPWS clients and integrate DPWS devices into OSGi. We are planning to release this extension soon.

To sum up our plans for the near future:

• Release version 0.8 and 0.7.1 of ws4d-gsoap. Version 0.8 supports the latest version of the WS-DD specifications and has new features like DPWS security support, scope matching support, lwIP support, fixed interoperability issues with vista and windows 7 and maybe RTnet support. Version 0.7 simply fixes basic bugs related to the build system.
• Release ws4d-pipes
• Release OSGi integration for JMEDS

We have recently published a new revision of the Java Multi Edition DPWS Stack (JMEDS). It contains many improvements the community reported to us. We suggest all developers to try out this new release. Get it here (Filereleases) or here (SVN). Have fun.

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.

Version 0.9.5 of the WS4D JavaME stack is now available on SourceForge. As usual, the release includes ready-to-use JAR files (of various flavours), documentation and source code. Major improvements in this release:

• DPWS Security
• Multi-Device
• Action Parameter overloading
• WSDL Repository
• Properties Handling (via XML configuration file)
• Discovery Proxy
• Critical bug-fixes

We suggest all developers to try out this release. Feedback is always highly appreciated (Please use the discussion forums or trackers hosted on our SourceForge project pages). Have fun.

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!
