java - JaNeLA 报告有关有效 JNLP 的错误

Question

我正在使用一个名为 JaNeLA 的工具来检查我的应用程序的 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>

它报告了:

JaNeLA Report - version 11.05.17


Report for file:/C:/Users/Desktop/myapp.jnlp

Content type application/xml does not equal expected type of application/x-java-jnlp-file

XML encoding not known, but declared as utf-8
Codebase + href 'http://myserver.com/C:/Users/Desktop/myapp.jnlp' is not equal to actual location of 'file:/C:/Users/Desktop/myapp.jnlp'.
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.

我不确定的是 JaNeLA 报告存在无效内容，即 Invalid content was found starting with element 'homepage'。需要“{description, icon, offline-allowed, shortcut, association, related-content}”之一。 在上面的 JNLP 中满足此条件。

此外，它还报告有关 发现以元素“update”开头的无效内容。此时不需要子元素。 根据我所见，也满足此条件。

不确定它为什么报告(红色)有效的 JNLP 内容。任何帮助将不胜感激。

此 JNLP 以正确的顺序放置元素。请注意，两个 元素都是通过将元素进一步移到文档中 来固定的 - 就像我上面建议的那样。

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" xmlns:jfx="http://javafx.com" codebase="http://myserver.com/downloads">

    <shortcut online="true">

      <menu submenu="My App"/>

</jnlp>

另一个问题，换个JNLP，彻底卸载当前的app。使用 Java 控制面板，并重新加载它。
