Java
附件是客户端代码，做了一些改造。主要是清除一些模块之间的关联，避免关联下载。
为了更快的启动客户端、最少的下载gui更新程序，我尝试了如下做法：
1. 个模块分开打包。目前粒度是对各第三方jar包、common目录、gui下的个子目录、gui目录本身做了单独打包、签名、pack200；
2. 设置各个包的下载策略。对于少数必须包，用eager；对于非必须包（例如各模块包、itext包等），一律用lazy处理；
3. 首次启动客户端，尽可能快、少下载包。目前可以只下载必要包（见后续列表，并且还有改进潜力）。目前可以做到LoginUI出现时，不下载任何业务模块。
4. 由于MainUI关联了不少各模块的东西（例如工具栏上有一些业务模块的快捷入口），启动程序时候应当避免加载MainUI类。所以，改造XXX的main函数到Main.java中，而不再放在MainUI中；
5. 通过观察以前代码jnlp的jar加载发现，login界面出来时候eng包竟然已经被加载。调试发现ClientInitialize类中调用了PartType数量。必要性不大，去掉之；
6. 启动MainUI，什么也没动的情况下，发现几乎所有业务模块jar都被加载。原因是：MainUIActionManager里面的clear方法在清除缓存时候，用硬编码调用各个模块的类的静态方法进行clear，导致这些jar包全都被加载。做如下改造：在MainUIActionManager中做一个map存储所有待清除类，用类名和方法名记录clear cache的方法；各个具体模块的类如果有需要logout被清除的，在类的开始处用static代码段调用 MainUIActionManager.registerClearCache来注册自己。这样，MainUIActionManager就不必知道每个被清除者，谁注册谁会被回调。这里的缺点是：由于这些clear方法都是static的，无法用接口来定义，java没有abstract static这样的概念，这里只能用反射，有一定的出错概率。经过这个改造，mainUI启动后，业务模块大多没有load，只有eng、sales和 manage来死活在上面。
7. 继续研究eng模块jar包总是被加载。发现原因是：默认进来的HomePage就是PartHomePage。这个看来没招了。不过sales和manage还要研究。
8. 继续发现：part首页出现后，sales模块总是被加载。后来发现是AbstractHomePage类中的addInfoCenterTab方法中，竟然用SalesUtil.getString获得tab的title字符串。去掉，sales模块不再加载。
9. 继续发现：part首页出现后，manage模块jar总是被加载。后来发现，part首页的infoCenter要显示InfoCenter的UI，而这些类是在manage包内定义的。抽出来放在eng模块，让manage引用eng模块。manage模块不再被加载。
通过以上改造，首次运行XXX，到LoginUI显示时，加载的XXX的包如下：
XXX-base.jar
XXX-common.jar
XXX-gui.jar
XXX-i18n.jar
XXX-image.jar
XXX-server.jar
XXX-swing.jar
org.jar
第三方包有：
commons-lang.jar
jbossall-client.jar
looks-1.3.1.jar
twaver.jar
总计大小：3.439m。而且应当还有改进潜力。
点击login到进入MainUI，期间被加载的包有：
XXX-comany
XXX-conf
XXX-message
XXX-print
XXX-security
总计大小（包含前面加载的）：3.995m
如果点击树将各个模块触发全部jar下载，累计总计大小：7.116m
以后：
* 如果某个业务模块被具体更新：从双击jnlp到MainUI显示出来未做任何动作之前，没有任何下载产生（相当于直接启动）；点击对应的模块树会触发下载，但一般模块包的jar包都在1m以下，相当于下载一个新闻网页，略感延迟但不明显；只要下载服务器和客户端网络较好，基本感觉不到更新；
* 如果客户端基本包（包括common、gui包、image、base、swing等）被更新，双击jnlp会触发进度条进行下载更新，不过会提示，用户可以选择；这是因为在jnlp中做了如下设置：<update check="background" policy="prompt-update"/>，用户可以选择不更新而启动客户端（当然这样风险相当大）；
* 如果第三方包被更新：同上。
附件的jnlp文件是新版本，可以看一下。为了方便管理众多gz和jar文件，将所有压缩包放入webstart/jars目录下，上层目录只留下index.htm和jnlp文件。
附件中的bat文件，可以将class文件进行打包、repack、签名、pack200压缩、生成对应的空jar文件、move到jboss目录，一次搞定（使用前需要修改一下里面的目录）。
