JavaFX Web Start failure – FailedDownloadException: Unable to load resource:

Question

I have deployed JavaFX app to web. At local host works fine only applet. Runned from a file works both – applet and web start.

But after deploying to web server I got this exception (probably for both of them):

Ignored exception: ExitException[ 3]com.sun.deploy.net.FailedDownloadException: Unable to load resource: file:/C:/Users/Jan/AppData/Local/Microsoft/Windows/INetCache/IE/jar/myapp.jar

JNLP:

Disclaimer: I'm the maintainer of the javafx-maven-plugin.

Please have a closer look at the jar-path: <jar href="..\jar\myapp.jar" size="63799"/>

The problem is the href-part, because it contains backslashes which is not converted to slashes on linux-webservers.

When using the javafx-maven-plugin, this already got reported and I have created a workaround for this, but I still need to open an issue on the java bugtracker ;)

Even on SO this was reported: How to specify the JNLP output file when using javafx-maven-plugin for creating a javafx native installer?
