DataManager is a library that provides a shared memory pool to allocate buffers from. It includes the necessary things to build servers which regulary produce data and provide them via ringbuffers to clients. It includes the common framework to have locking and various access methods. The use generally boils down to simple get()s and put()s. This project is no longer under active development.
EJOE is a lightweight Java remoting framework built to send and receive objects through pluggable (de)serialization mechanisms. It offers a high-performance, simple, and clean object request broker (whereby ORB is meant in its natural manner and not in its relation with CORBA), with server and client components for your client/server applications. It's a highly scalable implementation of the common request-process-response pattern based on Java NIO. It does support optional remote class loading to avoid redundant classpath entries, but doesn't require stubs and/or proxy objects.
Enterprise Object Broker (EOB) is an application server that transparently distributes Java objects via their interfaces. It makes no distinction between Local and Remote objects. Because of these features, it is not J2EE compliant. The developer builds beans that implement normal Java interfaces and the deployer decides where the beans are in a cluster of servers. Apache's AltRMI is used in place of RMI. It publishes plain interfaces locally and remotely. The interfaces do not have to extend the java.rmi.Remote interface. Methods do not have to throw RemoteException. AltRMI delivers remoting for Java. EOB sits on top of Apache's Avalon-Phoenix server platform.
GUPnP is an object-oriented open source framework for creating UPnP devices and control points, written in C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient, and flexible. The GUPnP framework consists of two libraries. GSSDP implements resource discovery and announcement over SSDP, and GUPnP implements the UPnP specification: resource announcement and discovery, description, control, event notification, and presentation (basic Web server functionality through libsoup). GUPnP does not include helpers for construction or control of specific standardized resources (e.g. MediaServer); this is left for higher level libraries utilizing the GUPnP framework.
