Creating a desktop icon using JWS JNLP for a JavaFX app
提问by mikewilliamson
I am trying to get a custom destop icon to be displayed for my app but for some reason no matter what I do the same default java icon shows up. I have tried everything I can think of and gone and compared my jnlp file with others whose icons seem to work ok. According to everything I have read the following should work fine. But of course, it doesn't:
我正在尝试为我的应用程序显示一个自定义的 destop 图标，但出于某种原因，无论我做什么，都会显示相同的默认 Java 图标。我已经尝试了我能想到的所有方法，然后将我的 jnlp 文件与其他图标似乎工作正常的文件进行了比较。根据我阅读的所有内容，以下内容应该可以正常工作。但当然，它不会：

<icon kind="shortcut" href="res/icon64x64.png" width="64" height="64"/>

Any ideas would be greatly appreciated.
任何想法将不胜感激。

I would try the following, in order:
我会按顺序尝试以下操作：
- Create an icon of 32x32 in size and add it as an additional
<icon kind="shortcut".... The specsays that size is used for desktop icons. Use your 64x64 icon as the "default". For example, your new
<icon>elements would be:<icon href="res/icon64x64.png" width="64" height="64"/> <icon kind="shortcut" href="res/icon32x32.png" width="32" height="32"/> <icon kind="shortcut" href="res/icon64x64.png" width="64" height="64"/>Remember that your images are accessed relative to your
codebaseattribute in yourjnlpxml elementIf none of those work, you are welcome to compare your JNLP to one of mine that works.
- 创建一个 32x32 大小的图标并将其添加为附加
<icon kind="shortcut".... 该规范说，大小用于桌面图标。 使用您的 64x64 图标作为“默认”。例如，您的新
<icon>元素将是：<icon href="res/icon64x64.png" width="64" height="64"/> <icon kind="shortcut" href="res/icon32x32.png" width="32" height="32"/> <icon kind="shortcut" href="res/icon64x64.png" width="64" height="64"/>请记住，您的图像是相对于您
codebase的jnlpxml 元素中的属性访问的如果这些都不起作用，欢迎您将您的 JNLP 与我的JNLP 进行比较。
I realize that this JNLP stuff is kind of a pain. Hope one of these work for you.
我意识到这个 JNLP 的东西有点痛苦。希望其中之一对您有用。

I suppose the problem in your case is the missing CODEBASE attribute. See one working snippet:
我想你的问题是缺少 CODEBASE 属性。查看一个工作片段：
<?xml version="1.0"?>
<jnlp spec="1.5+"
codebase="http://www.sweethome3d.com/"
href="SweetHome3D.jnlp">
<information>
<title>Sweet Home 3D</title>
<vendor>eTeks</vendor>
<homepage href="http://www.sweethome3d.com/"/>
<description>Sweet Home 3D</description>
<description kind="short">Arrange the furniture of your house</description>
<icon href="SweetHome3DIcon.gif"/>
<icon kind="splash" href="SweetHome3DSplashScreen.jpg"/>
<offline-allowed/>
<shortcut online="false">
<desktop/>
<menu submenu="eTeks Sweet Home 3D"/>
</shortcut>
<association extensions="sh3d sh3l sh3f sh3t sh3p"
mime-type="application/SweetHome3D"/>

We had the same problem. It worked fine initially then over time (a few Java updates?) it stopped working. When I got around to troubleshooting I discovered that even though javaws sends that it is gzip capable, our gzip response was not handled. I turned gzip off for these icons and it worked fine once again.
我们遇到了同样的问题。它最初运行良好，然后随着时间的推移（一些 Java 更新？）它停止工作。当我开始进行故障排除时，我发现即使 javaws 发送它支持 gzip，我们的 gzip 响应也没有被处理。我为这些图标关闭了 gzip，它再次正常工作。

I don't have a specific answer I'm afraid, but Project MaiTaiis an open source application written in JavaFX, and that has a custom desktop icon.
恐怕我没有具体的答案，但Project MaiTai是一个用 JavaFX 编写的开源应用程序，它有一个自定义桌面图标。
If you haven't done so already, maybe checking the JNLP code for MaiTai would give you some pointers.
如果您还没有这样做，也许检查 MaiTai 的 JNLP 代码会给您一些提示。

There's an example of how to do this in the JavaFX in Action book, if you have access to that. You need to make sure the res/icon64x64.png file is actually downloadable from whatever site the app is hosted on, relative to the JNLP's location. Try loading it directly in a browser to ensure its available/valid.
如果您有权访问，JavaFX in Action 书中有一个示例说明如何执行此操作。您需要确保 res/icon64x64.png 文件实际上可以从托管应用程序的任何站点下载，相对于 JNLP 的位置。尝试直接在浏览器中加载它以确保其可用/有效。
