hal4java

A Java library to read DBUS messages fired from the LINUX HAL subsystem. While the Java code is OS agnostic, the DBUS interface requires a small native library, so presently this only runs on LINUX. (Library source is included if you wish to cross-compile.) HAL is the Linux hardware abstraction layer. It provides an abstraction layer between the kernel and applications, enabling hardware plug-and-play support. Java applications typically cannot directly query the hardware layer. This package provides a method to listen for HAL events. It enables plug-and-play actions in Java. For example: when a particular USB device is plugged into the system, a JAVA-based listener is alerted with a "deviceAdded" event and can take appropriate action ... like reading or writing to/from the device. Another example is ad-hoc networking, where network interfaces may be created and destroyed by the LINUX kernel depending upon network availability (cable plugged in, wirel
