Java Web Start应用程序无法从快捷方式更新
作者：互联网
我使用Java Web Start部署了一个Java(FX)桌面应用程序.更新工作正常,但只有当我手动运行下载的JNLP时,它们才能从安装到桌面和菜单的快捷方式起作用.
这是我的JNLP：

以防万一,这是我的程序中安装快捷方式的部分：
// 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);
}
更新1
我删除了< offline-allowed />现在它从快捷方式更新但我无法离线启动应用程序.显然我应该能够？它给了我这个错误：
公平地说,我确实尝试在启动时连接到服务器,但这不会导致此错误：它有2秒超时,看起来像这样：
try
{
isOffline = !(InetAddress.getByName(Config.domain + "." + Config.serverDomain).isReachable(2000));
}
catch (IOException e)
{
e.printStackTrace();
}
无论如何,错误中没有引用我的代码,所以我想如果我没有< offline-allowed />我根本无法离线运行应用程序？这是真的？如果是的话,这对于使用JWS进行部署来说是一个巨大的问题,我可能只是完全放弃了……
更新2
我想我可能会这样：http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7121086有谁知道一个解决方法？
在它说的错误
Get rif of every jnlp used as extension. meaning mix all in one. At this condition that works
所以我应该将JavaFX作为jar混合到我的JNLP中？
解决方法:
我设法在不删除< offline-allowed />的情况下解决了问题,这里是JNLP：

为了确保服务器正确处理更新,请为Apache安装mod_expires并将此.htaccess放在JNLP和JAR所在的文件夹中：
DirectoryIndex index.html
AddType application/x-java-jnlp-file .jnlp
AddType application/x-java-archive .jar
AddType application/x-java-archive-diff .jardiff
<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "modification"
</IfModule>
