JaNeLA報告關於有效的JNLP的錯誤

Question

我正在使用名爲JaNeLA的工具來檢查我的應用程序的JNLP文件。

我的JNLP是：

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="6.0+" xmlns:jfx="http://javafx.com" codebase="http://myserver.com/downloads"> 
    <information> 
    <title>My App</title> 
    <vendor>My Vendor</vendor> 
    <description>Application to do something</description> 
    <homepage href="http://myserver.com/myapp" /> 
    <offline-allowed/> 
    <shortcut online="true"> 
     <desktop/> 
     <menu submenu="My App"/> 
    </shortcut> 
    </information> 

    <security> 
    <all-permissions/> 
    </security> 

    <resources> 
    <j2se version="1.7.0_25" java-vm-args="-Xmx1024m -Djava.net.preferIPv4Stack=true" href="http://java.sun.com/products/autodl/j2se"/> 
    <property name="myID" value="1" /> 
    </resources> 

    <resources os="Windows" arch="x86"> 
    <jar href="my-app-0.0.1.jar" download="eager" /> 
    </resources> 

    <resources os="Windows" arch="amd64"> 
    <jar href="map-app-0.0.1.jar" download="eager" /> 
    </resources> 

    <application-desc main-class="com.myApp.MyApp"/> 

    <update check="always"/> 

</jnlp> 

它報告有關：

JaNeLA Report - version 11.05.17

Desktop icons were subject to bug nnnn in earlier J2SE versions 
Downloads can be optimized by specifying a resource size for 'myapp-0.0.1.jar'. 
The resource download at myapp-0.0.1.jar can be optimized by removing the (default) value of download='eager'. 
The resource download at myapp-0.0.1.jar can be optimized by removing the (default) value of main='false'. 
It might be possible to optimize the start-up of the app. by specifying download='lazy' for the myapp-0.0.1.jar resource. 
Lazy downloads might not work as expected for myapp-0.0.1.jar unless the download 'part' is specified.

我什麼不知道的是，JaNeLA報告大約有是無效的內容，即Invalid content was found starting with element 'homepage'. One of '{description, icon, offline-allowed, shortcut, association, related-content}' is expected.這種情況在滿足上面的JNLP。

此外，它報告Invalid content was found starting with element 'update'. No child element is expected at this point.這個條件也符合我所看到的。

不確定爲什麼它報告（紅色）關於有效的JNLP內容。任何幫助將不勝感激。

此JNLP按正確的順序放置元素。請注意，兩個元素都被固定，將元素向上移到文檔 - 就像我上面所建議的那樣。

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="6.0+" xmlns:jfx="http://javafx.com" codebase="http://myserver.com/downloads"> 
    <information> 
    <title>My App</title> 
    <vendor>My Vendor</vendor> 
    <homepage href="http://myserver.com/myapp" /> 
    <description>Application to do something</description> 
    <offline-allowed/> 
    <shortcut online="true"> 
     <desktop/> 
     <menu submenu="My App"/> 
    </shortcut> 
    </information> 
    <security> 
    <all-permissions/> 
    </security> 
    <update check="always"/> 
    <resources> 
    <j2se version="1.7.0_25" java-vm-args="-Xmx1024m -Djava.net.preferIPv4Stack=true" href="http://java.sun.com/products/autodl/j2se"/> 
    <property name="myID" value="1" /> 
    </resources> 
    <resources os="Windows" arch="x86"> 
    <jar href="my-app-0.0.1.jar" download="eager" /> 
    </resources> 
    <resources os="Windows" arch="amd64"> 
    <jar href="map-app-0.0.1.jar" download="eager" /> 
    </resources> 
    <application-desc main-class="com.myApp.MyApp"/> 
</jnlp> 

至於另一個問題，改變JNLP，完全卸載當前的應用程序。使用Java控制面板，並加載新鮮。
