Iman Habib writes "Sanos is a minimalistic 32-bit x86 OS kernel for jbox appliances. A jbox is a JavaOS server appliance running on standard PC hardware. This enables you to run Java server applications without the need to install a traditional host operating system like Windows or Linux. Only a standard Java HotSpot VM and the sanos kernel are needed. The kernel was developed as part of an experiment on investigating the feasibility of running Java server applications without a traditional operating system only using a simple kernel. The kernel implements basic operating system services like booting, memory management, thread scheduling, local and remote file systems, TCP/IP networking and DLL loading and linking. A thin win32 wrapper allows the Windows version of the standard HotSpot JVM to run under Sanos, essentially providing a JavaOS platform for server applications. This enables you to run java based server applications, like Tomcat and Jboss, under Sanos. Sanos is open source under a BSD-style license."
