NetKernel

NetKernel is a resource oriented microkernel and RESTful application server created from the convergence and unification of the powerful fundamental concepts found in the World Wide Web and Unix.

NKSE includes extensive functionality including transports (HTTP, SOAP 1.1 / 1.2, REST Web-Services, JMS, Cron, etc.) services (XML and image pipeline processing, RDBMS access, SMTP/POP client, etc), tools (debugger, unit testing, etc.) and a rich set of supported programming languages (Java, Python, JavaScript, Groovy, Beanshell, XRL, DPML, etc.).

NetKernel is used in a wide range of applications, from web sites, corporate information integration systems, telecoms infrastructure, digital libraries, high-performance AJAX based systems even innovative RESTful graphical apps (such as the bundled Ping Pong application),

NetKernel Stack

NetKernel是一个软件系统，它将REST和Unix的基本属性组装成一个叫做面向资源计算（resource oriented computing，ROC）的强大的抽象集。面向资源计算的核心是将信息（资源）的逻辑请求与传递请求的物理机制（代码）相分离。与其他方式相比，使用ROC构建的应用已被证明是小巧的、简单的、灵活的，并且无需太多代码。

Scripting

JavaScript program processes

Language runtimes are activated by calling the runtime as an active: service. NetKernel 3.3 supports:

active:beanshell

active:beanshell+operator@ffcpl:/myprogram.bsh

active:javascript

active:javascript+operator@ffcpl:/program.js+data@ffcpl:/data.xml

active:groovy
active:python
active:ruby

The following versions of script language runtimes are used in NetKernel 3.3.

BeanShell v1.3.0
JRuby 1.0.1
Rhino Javascript v1.6 R2 - with patches to E4X
Groovy v1.0 JSR 05
Jython v2.2
