As we know, in the modern enterprise system architecture design, the API is becoming more and more key important issue. meanwhile more and more companies use the private cloud (such as PAAS) to server their services and combine their data each other to make more useful.

So as a developer, we should good at these technologies, in the most of enterprise API implement method tech list, the JAVA language and RESTful way is first choice for us. as it use simple JSON data format to transfer data from each others, not only how to organize the data structure but also mock the invocation and debug test, it is very easy to implement. so I think we should keep familiar with these techs.

The below is a list which I list here for us to study:

1. Developing RESTful Services with JAX-RS 2.0, WebSockets, and JSON
2. RESTful Java with JAX-RS
3. RESTful Web Services
4. RESTful Web Services Cookbook
5. RESTful Web APIs
6. RESTful Java with JAX-RS 2.0, 2nd Edition
7. Java Web Services: Up and Running
8. Java EE 7 Essentials

V8是Google开发的一个javascript引擎。它是用C++写的，然后用于google开源的浏览器chrome中。

V8引擎实现了ECMAScript第五版 ECMA-262，能够运行于Windows，Mac OS X，还有那些使用IA-32,X64或者ARM的处理器的Linux上。

V8能够单独运行，或者嵌入到任何C++的程序中。

You can find more information here:

• The V8 documentation page which includes instructions on downloading and building V8.
• Performance documentation covering the performance goals of V8, and instructions on how to run the Octane benchmark suite (evolution of the V8 benchmark suite).
• User mailing list: http://groups.google.com/group/v8-users

OGNL表达式语言能够帮助我们访问存在于ValueStack和ActionContext中的值.

首先让我们来看看通过OGNL来访问一个String数组的变量.在action类中我们创建一个string数组,代码如下:

context.xml这个文件对于一个web工程来说是可选的.他包含一个<Context>标签.
他可以用来定义一个工程的自己行为.例如JNDI等.
