Section 1: JTWI (JSR 185) and Overview of JTWI-Compliant Wireless Applications
看看第一条：
Objective 1.1 Identify the goals and characteristics of the JTWI specification (JSR 185), including the mandatory specifications, conditionally required specifications, and the minimum configuration. Compare the relationship and differences between JTWI and other wireless Java technologies. |
JTWI的目标(Goals)，标准中原文是这样写的:
The goal of the JTWI specification is to improve the compatibility, interoperability and completeness of J2ME technology implementations in mobile phones.
提高手机中J2ME技术的兼容性，交互性和完整性
JTWI规定了一些规范，包括三类：
Mandatory(强制要求) , Conditionally Required(条件要求) and Minimum Configuration(最小配置).
这里JTWI对一些规范的内容做了调整：
MIDP 2.0 一些在MIDP2.0中可选optional的功能，在JTWI要求中变成强制要求mandatory。
MMAPI 1.1 JTWI强制要求一些媒体类型必须被支持。
1.2 Develop portable applications that are compatible with the requirements and restrictions an application programmer must adhere to, in order to ensure compatibility with a JTWI-compliant device, including resource minimums (standard-size application), clock resolution, and the use of preferred Multi-Purpose Internet Mail Extensions (MIME) names as applicable to Connected Limited Device Configuration (CLDC) 1.0 and 1.1, Mobile Information Device Profile (MIDP) 2.0, Wireless Messaging API (WMA) 1.1, and Mobile Media API (MMAPI) 1.1). |
就是要可以按照要求作出可以移植的应用，后面我们会慢慢学会的。
