以下是我的程序安装快捷方式的一部分：
//安装快捷方式
尝试
{
IntegrationService is = null;
try
{
is =（IntegrationService）ServiceManager.lookup（javax.jnlp.IntegrationService）;
}
catch（UnavailableServiceException use）
{
throw new ApplicationError（use.getLocalizedMessage（））;
}
如果（！is.hasDesktopShortcut（））
{
if（！is.requestShortcut（true，true，Companyapp））
{
throw new ApplicationError（Integration failed。）;
}
}
else
{
//initialController.dialog(\"短暂存在，离开！，null）;
}
}
catch（ApplicationError e）
{
initialController.dialog（无法在您的计算机上集成快捷方式。\Cause：+ e。 getLocalizedMessage（），我明白，null）;
}
更新1
我删除了< offline-allowed /> ，现在它从快捷方式更新，但是我无法启动应用程序离线。显然我应该能够它给我这个错误：
为了公平起见，我尝试在启动时连接到服务器，但这不会导致此错误：它有2秒的超时时间，如下所示：
try
{
isOffline =！（InetAddress.getByName（Config.domain +。 Config.serverDomain）.isReachable（2000））;
}
catch（IOException e）
{
e.printStackTrace（）;
}
无论如何，我的代码没有在错误中引用，所以我猜是否没有< offline-allowed /> 我无法离线运行应用程序？这是真的？如果是的话，这是使用JWS进行部署的一个巨大问题，我可能会直接把它完全丢弃。
更新2
我想我可能会碰到这个： http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7121086 任何人都知道解决方法？
在错误中，它说
获取每个jnlp作为扩展名的rif。意思是混合在一起。在这种情况下，
所以我应该将JavaFX作为一个jar混合到我的JNLP中？
解决方案
我设法解决问题，而不删除< offline-allowed /> ，这里是JNLP：

要确保服务器正确处理更新，请安装 mod_expires 为Apache，并将这个 .htaccess 在JNLP和JAR的文件夹中：

AddType application / x-java-archive-diff .jardiff

I have deployed a Java(FX) desktop app using Java Web Start. The updates work fine but only if I run the downloaded JNLP by hand, they do not work from shortcuts installed to desktop and menu.
Here is my JNLP:

</jnlp>
Just in case, here is the part of my program that installs the shortcuts:
// install shortcuts
try
{
IntegrationService is = null;
try
{
is = (IntegrationService) ServiceManager.lookup("javax.jnlp.IntegrationService");
}
catch (UnavailableServiceException use)
{
throw new ApplicationError(use.getLocalizedMessage());
}
if (!is.hasDesktopShortcut())
{
if (!is.requestShortcut(true, true, "Companyapp"))
{
throw new ApplicationError("Integration failed.");
}
}
else
{
//initialController.dialog("Shortcuts exist", "Go away!", null);
}
}
catch (ApplicationError e)
{
initialController.dialog("Failed to integrate a shortcut on your computer.\nCause: " + e.getLocalizedMessage(), "I understand", null);
}
Update 1
I removed <offline-allowed /> and now it updates from a shortcut but I can't start the application offline. So apparently I should be able to? Its giving me this error:
To be fair, I do try to connect to a server on startup, but that is not causing this error: it has a 2 second timeout and looks like that:
try
{
isOffline = !(InetAddress.getByName(Config.domain + "." + Config.serverDomain).isReachable(2000));
}
catch (IOException e)
{
e.printStackTrace();
}
Irregardless, my code is not referenced in the error, so I guess if I don't have <offline-allowed /> I cannot run the app offline at all? Is this true? If yes, this is a massive problem for deployment with JWS, I'll probably just ditch it altogether...
Update 2
I think I may be hitting this: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7121086 anyone knows a workaround?
In the bug it says
Get rif of every jnlp used as extension. meaning mix all in one. At this condition that works
So I should mix JavaFX as a jar into my JNLP?
解决方案
I managed to solve the problem without removing <offline-allowed />, here is the JNLP:

AddType application/x-java-archive-diff .jardiff
