爲包含Applet的原因已經加載我在Java調用webproject外部庫

嗨，我寫一個包含小程序的Web應用程序，我使用這個標記來開始我的小應用程序的HTML頁面爲包含Applet的原因已經加載我在Java調用webproject外部庫

<applet codebase="http://localhost:8084/WebForSpark" code="AppletBroadcaster.ZkusebniApplet" archive="AppletBroadcaster.jar, jave.jar " width="500" height="500"></applet>

我需要使用外部庫安裝插件。 jar在我的applet中，所以我將這個文件手動添加到我的Web項目的bulid/web文件夾中。所以一切運行良好。當運行我webproject Java控制檯寫這個

Basic: Plugin2ClassLoader.getPermissions CeilingPolicy allPerms

所以很明顯，jave.jar在我的生成/ Web文件夾成立。

，但是當我在我的小程序按下按鈕從jave.jar做一些操作，javaconsole寫這

所有我應該做jave.jar做得正確，但我的問題是，爲什麼是如此很多時候所謂的lib/jave.jar當我jave.jar是

http://localhost:8084/WebForSpark/

和小程序的啓動過程中加載sucefully ...我可以沒有呼叫的lib/jave.jar做什麼和爲什麼它被稱爲？非常感謝

目前applet元素歸結爲。

<applet 
    codebase="http://localhost:8084/WebForSpark" 
    code="AppletBroadcaster.ZkusebniApplet" 
    archive="AppletBroadcaster.jar, jave.jar" 
    width="500" 
    height="500"> 
</applet>

這將使JRE搜索的Jar在http://localhost:8084/WebForSpark &（如若不然），其是在它從相同的路徑（或根據包子目錄）的任何類。我懷疑jave.jar實際上是另一個地方，所以archive屬性應該更像：

<applet 
    codebase="http://localhost:8084/WebForSpark" 
    code="AppletBroadcaster.ZkusebniApplet" 
    archive="AppletBroadcaster.jar, /path/to/jave.jar" 
    width="500" 
    height="500"> 
</applet>

凡/path/to/可能是/lib/或其他路徑。

感謝您的回覆，但我完全不瞭解你。我沒有在我的build/web文件夾中找到像lib這樣的任何文件夾或軟件包。我沒有明確告訴Java她應該搜索WebForSpark/lib/jave.jar，但是我的jave.jar位於index.html旁邊的web（CODEBASE）的根目錄中。只有在使用lib文件夾的地方在我的小程序項目中，但是在applets中它卻不是。我的心不是英語精確，所以請儘量給我寫您anothers字的意思.. –

URL是從基本代碼+ Archvive組成所以在我的情況下爲http：//本地主機：8084/WebForSpark + jave.jar看到我的第一個javaconsole日誌從第9行開始就有JRE如何溝通和下載jave.jar。是的，我可以在瀏覽器中使用JAVE.JAR，這對我來說是一個新的壞消息......我沒有察覺到它，這是真的很大的安全問題，我必須把我的庫放在另一個地方，用戶無法通過瀏覽器訪問它們。但在哪裏... –

所以我做了一些實驗。我嘗試在myroot中創建文件夾庫，並將jar放入。將lib添加到代碼庫中會導致/WebForSpark/lib/lib/jave.jar，因此我嘗試將代碼庫設置爲僅返回到/ WebForSpark，現在它運行良好。但我不真正理解爲什麼......我的小應用程序jar被複制到代碼庫和其他jar在lib文件夾中，並且都被sucessfuly加載..在一些connfigration文件中必須記住JRE必須在codebase/lib文件夾中搜索jar，但是在哪裏。並再次 - 我可以訪問罐子inlib文件夾trouhgt瀏覽器，哪裏是罐子安全的地方？ –
