EPOSWorkspace

Epos Workspace is a framework to start services, start web-services, load classes, and publish the functions of Java objects via XML/RPC. It is a slimmed down version of the workspace developed for the epos project by Andreas Lauer.

Main features

• describe services using service.xml files
• organize sub-projects and services similar to web applications
• start web-applications and java applications together (using Jetty)
• publish Java objects via XML/RPC (using apache xml/rpc)
• easy to learn, easy to debug, easy to use.

Download

Objectives

• reduced dependencies to DFKI packages
• changes for better usability (e.g. service dependency declarations, managed default resource handling)
