JNLP不下載操作系統資源

Question

我有一個程序，我一直在寫使用WebStart，我似乎遇到了一個問題。我注意到無論我做什麼，我都無法讓WebStart下載操作系統特定的jar。

下面你會看到我的JNLP文件。你看看資源你會注意到我有一些操作系統和架構獨立的瓶子，然後我有一些操作系統相關的罐子和nativelibs。

目前，核心文件夾和通用文件夾中的所有內容都將正確加載，但沒有其他功能。如果我製作一個單獨的jnlp文件來鏈接我的電腦所需的所有內容，它將會下載並加載得很好（有很少的打嗝）。

這是我的JNLP文件，你看到什麼可能是錯的？

Answer 1

Java Web Start描述符中的「Resource」標記有兩個關鍵元素以允許高效的Java應用程序部署。資源標籤的一個重要屬性是「os」屬性。該屬性允許您爲應用程序的部署指定特定的平臺。 「os」屬性中的選項可以是「Windows」，「Linux」，「Mac OS X」等。

下一個相關資源屬性是「arch」屬性。該屬性允許指定處理器體系結構。對於「拱」相關屬性的值包括「86「和「AMD64」（即使是英特爾64位）

你需要指定正確爲其拱版本您正在使用這些特定的OS依賴庫。
其他拱值可以是：

<resources os="Linux" arch="i386 x86" > 
... 
</resources> 

<resources os="Linux" arch="amd64" > 
... 
</resources> 

<resources os="Windows" arch="x86" > 
... 
</resources> 

<resources os="Windows" arch="amd64" > 
... 
</resources> 

<resources os="Mac\ OS\ X" arch="x86_64" > 
... 
</resources> 

<resources os="Mac\ OS\ X" arch="i386 x86"> 
... 
</resources> 

希望這有助於。
