WebMotion is a Web application development framework based on a REST architecture and the Java EE 6 standard. It features a presentation layer management using pages (JSP, HTML, etc.) and REST service exposition (e.g. XHR calls). It enables you to serialize service results into JSON or XML. The framework has deliberately limited capabilities, but it focuses on the ease of use. It leaves open the choice of persistence framework, dependency injection, and validation.
Overthere is a Java library to manipulate files and execute processes on remote hosts, i.e. do stuff "over there". It was built for and is used in the XebiaLabs deployment automation product Deployit as a way to perform tasks on remote hosts, e.g. copy configuration files, install EAR files, or restart Web servers. Another way of looking at it is to say that Overthere gives you java.io.File and java.lang.Process as they should have been: as interfaces, created by a factory and extensible through an SPI mechanism.
