Features of the JMEDS Framework
This document summarizes the features of the JMEDS (Java Multi Edition DPWS Stack) Framework which implements the Devices Profile for Web Services specification.
Versatility of the platform Supports all Java Editions
The JMEDS Local Toolkit feature supports all Java platforms from CLDC up to SE and allows the usage of platform specific features like disk and network access. With JMEDS it is possible to choose the best platform for purpose.
JMEDS is suitable for embedded devices with low amount of memory and restricted computing power as well as for computing systems without such limitations. The modularity of JMEDS allows the usage of different modules to fit the needs of your project and ensures high adaptability.
With the module system it is possible to reduce the size of JMEDS to save resources on your device. JMEDS uses only a minimal set of external libraries to minimize the necessary dependencies. JMEDS is a lightweight frame work.
Generic web interface
JMEDS comes along with a generic web interface which allows fast access and usage of your services with your favorite web browser.
Interpretation of WSDL at Runtime
It is not necessary to create a WSDL neither for your service nor for your device. The JMEDS generates the WSDL on the fly within the request.
JMEDS is build for high compatibility, supports Microsoft Windows 7 and is tested with the University of Rostock DPWS Stack.
License / Costs
JMEDS is open source under the license of EPL (Eclipse Public License).
