【ZK开发】环境搭建
一，为什么要写【ZK开发】系列文章
使用zk开发，已经2年多了，从zk3.0到现在以及即将发布的zk5.0.3，只因没有写blog的习惯，很多知识点都是使用脑细胞去记忆，随着时间的推移，它们早晚有一天将不复存在，好脑子不如烂笔头，特此记下，以方便日后查阅
二，准备
1，运行环境
Tomcat eclipse Plug-in 附件内 或点这里
2，ZK版本的选择
zk5之前的版本为免费版，从zk5开始，分化出免费社区CE版，收费PE专业版,EE企业版，详细区别见这里，根据自己所需功能和费用承受能力选择
3，Zk学习
首先我们要了解zk的架构、组件、页面、桌面、事件、执行流程、运行机制等等基本概念，对Zk有一个基本轮廓及具体概念的把握。以下是学习资源：
- Zk学习资源列表
- Zk3.5.1 开发手册pdf版
- Zk3.5.1在线版
- Zk官方small talk 和文档库
- JE zk圈子
- Zk交流群25891428
三，环境搭建
1，基于环境与版本：内容基于（二）1中环境，Zk版本选择5.0.2 CE版
2，设置java源码编码方式：源码的编码用utf-8格式，
具体配置： Window menu --> Preferences --> Generals --> Content Types --> Text --> Java Source File --> Default Encoding --> Update --> OK
3，tomcat插件配置：将附件内 tomcat 插件copy到eclipse目录D:\eclipse\plugins，重启tomcat
关联Tomcat: Window menu --> Preferences --> Tomcat --> Tomcat Version --> Tomcat6.x --> Tomcat Home --> Brower >选择安装的Tomcat根目录 --> Context declaration mode --> Context files --> ok
4， 创建Zk项目：File menu --> new --> Dynamic Web Project --> 输入Project Name ,本例输入zk5
关键步骤：由于eclipse默认java文件编译后放在zk5/build/classes文件中，实际使用时，我们应该让其编译到
zk5/WebContent/WEB-INF/classes 目录内
如何修改： zk5项目上右键 --> Properties --> Java Build Path --> Source选项卡，在视图最下 Default output folder输入zk5/WebContent/WEB-INF/classes保存
如果未配置以上内容，一般会出现 xxxx.class is NotFoundException
5，复制相应jar及配置文件到web-inf/lib目录内，最终目录结构如下图
web.xml内容如下：

6， 演示Hello World ,创建一个zul首页
- *.zul是zk页面的默认后缀，此类页面使用xml语法，但是eclipse默认不支持*.zul扩展的文件，所以无法表示*.zul是一个xml语法的文件，继而不会高亮显示*.zul中xml格式的元素、属性等，
- 如果让eclipse识别*.zul是xml格式文件呢：Window Menu -->Preferences -->Generals --> Content Type -->Text --> xml --> 点击add按钮 -->输入*.zul -->Ok 这样*.zul扩展的文件eclipse会识别其为xml文件格式
下面在/WEB-INF/content/上右键 New file > 选择 file >输入index.zul --> ok

zk xml 命名空间及其作用：
http://www.w3.org/1999/xhtml 为zk定义的xhtml组件集
http://www.zkoss.org/2005/zk/native 为本地代码，即静态html代码，zk框架不解析，直接输出

7，项目的部署
（1）右键 WebContent --> Properties -->Resources -->复制Location --> E:\workspaces\dev_eclipse\zk5\WebContent
（2）在D:\Tomcat6.0\conf\Catalina\localhost文件夹内创建，文件zk5.xml,输入如下内容，
<?xml version="1.0" encoding="utf-8"?> <Context docBase="E:\workspaces\dev_eclipse\zk5\WebContent" path="/zk5" reloadable="true"/>
其中docBase为1中复制的内容，path可写可不写，虚拟目录由xml文件zk5.xml的文件名决定
（3）点击Eclipse工具栏的Tomcat图标，启动tomcat，效果如下图
四，总结
本文主要介绍eclipse的使用及zk环境的搭配，其中一些细节是开发中遇到的问题，以及解决方法。
后续会一点点介绍【ZK开发】中的一些技术的使用及原理
