JavaFX MediaBox exception: Connection refused: connect.

please see http://hilaltarakci.blogspot.com/2011/03/revisited-using-java-fx-app-in-web.html for background of this post.

Problem

When you build the JavaFX MediaBox component (or a modified version of it), Netbeans 6.9.1 ide produces the following files under dist folder.

MediaBox.html

MediaBox.jar

MediaBox.jar.pack.gz

MediaBox.jnlp

MediaBox_browser.jnlp

When you move those files to production environment (some other location or a web server), you may get the following error, when you try to see MediaBox.html via a browser.

exception: Connection refused: connect.

java.net.ConnectException: Connection refused: connect

at java.net.PlainSocketImpl.socketConnect(Native Method)

at java.net.PlainSocketImpl.doConnect(Unknown Source)

.....

at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Exception: java.net.ConnectException: Connection refused: connect

Solution

In my case, this was due to .jnlp files.

Editing codebase and homepage attributes accordingly in both MediaBox.jnlp and MediaBox_browser.jnlp files fixed the issue.
