Java
附件是客戶端代碼，做了一些改造。主要是清除一些模塊之間的關聯，避免關聯下載。
為了更快的啟動客戶端、最少的下載gui更新程序，我嘗試了如下做法：
?? 1. 個模塊分開打包。目前粒度是對各第三方jar包、common目錄、gui下的個子目錄、gui目錄本身做了單獨打包、簽名、pack200；
?? 2. 設置各個包的下載策略。對于少數必須包，用eager；對于非必須包（例如各模塊包、itext包等），一律用lazy處理；
?? 3. 首次啟動客戶端，盡可能快、少下載包。目前可以只下載必要包（見后續列表，并且還有改進潛力）。目前可以做到LoginUI出現時，不下載任何業務模塊。
?? 4. 由于MainUI關聯了不少各模塊的東西（例如工具欄上有一些業務模塊的快捷入口），啟動程序時候應當避免加載MainUI類。所以，改造XXX的main函數到Main.java中，而不再放在MainUI中；
?? 5. 通過觀察以前代碼jnlp的jar加載發現，login界面出來時候eng包竟然已經被加載。調試發現ClientInitialize類中調用了PartType數量。必要性不大，去掉之；
?? 6. 啟動MainUI，什么也沒動的情況下，發現幾乎所有業務模塊jar都被加載。原因是：MainUIActionManager里面的clear方法在清除緩存時候，用硬編碼調用各個模塊的類的靜態方法進行clear，導致這些jar包全都被加載。做如下改造：在MainUIActionManager中做一個map存儲所有待清除類，用類名和方法名記錄clear cache的方法；各個具體模塊的類如果有需要logout被清除的，在類的開始處用static代碼段調用 MainUIActionManager.registerClearCache來注冊自己。這樣，MainUIActionManager就不必知道每個被清除者，誰注冊誰會被回調。這里的缺點是：由于這些clear方法都是static的，無法用接口來定義，java沒有abstract static這樣的概念，這里只能用反射，有一定的出錯概率。經過這個改造，mainUI啟動后，業務模塊大多沒有load，只有eng、sales和 manage來死活在上面。
?? 7. 繼續研究eng模塊jar包總是被加載。發現原因是：默認進來的HomePage就是PartHomePage。這個看來沒招了。不過sales和manage還要研究。
?? 8. 繼續發現：part首頁出現后，sales模塊總是被加載。后來發現是AbstractHomePage類中的addInfoCenterTab方法中，竟然用SalesUtil.getString獲得tab的title字符串。去掉，sales模塊不再加載。
?? 9. 繼續發現：part首頁出現后，manage模塊jar總是被加載。后來發現，part首頁的infoCenter要顯示InfoCenter的UI，而這些類是在manage包內定義的。抽出來放在eng模塊，讓manage引用eng模塊。manage模塊不再被加載。
通過以上改造，首次運行XXX，到LoginUI顯示時，加載的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
總計大小：3.439m。而且應當還有改進潛力。
點擊login到進入MainUI，期間被加載的包有：
XXX-comany
XXX-conf
XXX-message
XXX-print
XXX-security
總計大小（包含前面加載的）：3.995m
如果點擊樹將各個模塊觸發全部jar下載，累計總計大小：7.116m
以后：
??? * 如果某個業務模塊被具體更新：從雙擊jnlp到MainUI顯示出來未做任何動作之前，沒有任何下載產生（相當于直接啟動）；點擊對應的模塊樹會觸發下載，但一般模塊包的jar包都在1m以下，相當于下載一個新聞網頁，略感延遲但不明顯；只要下載服務器和客戶端網絡較好，基本感覺不到更新；
??? * 如果客戶端基本包（包括common、gui包、image、base、swing等）被更新，雙擊jnlp會觸發進度條進行下載更新，不過會提示，用戶可以選擇；這是因為在jnlp中做了如下設置：<update check="background" policy="prompt-update"/>，用戶可以選擇不更新而啟動客戶端（當然這樣風險相當大）；
??? * 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。為了方便管理眾多gz和jar文件，將所有壓縮包放入webstart/jars目錄下，上層目錄只留下index.htm和jnlp文件。
附件中的bat文件，可以將class文件進行打包、repack、簽名、pack200壓縮、生成對應的空jar文件、move到jboss目錄，一次搞定（使用前需要修改一下里面的目錄）。
