When using the DT for a Swing application (with embedded JavaFX content) the arguments are not passed to the main method of the application.

Sample JNLP file:

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="6.0+" codebase="http:/xxxx/" href="xxx.jnlp">
        <information>
                <title>XX</title>
                <vendor>XXX</vendor>
        </information>
        <security>
                <all-permissions />
        </security>
        <update check="always" policy="always" />
        <resources>
                <java version="1.7+" java-vm-args="-Xmx700m" />
                <jar href="http://xxxx/xx.jar" main="true" />
        </resources>
        <application-desc main-class="xx.xx.XX">
                <argument>-productive</argument>
                <argument>-dccphost</argument>
                <argument>ccc.org</argument>
        </application-desc>
</jnlp>

HTML file with DT:

<script src="http://java.com/js/dtjava.js"></script>
<script>
        function launchApplication(jnlpfile) {
        dtjava.launch(
            { url : jnlpfile },
            {
              javafx : '2.2+',
              toolkit: 'swing'
            },
            {}
        );
        return false;
        }
        </script>

<a href='xxx.jnlp'
        onclick="return launchApplication('xxx.jnlp');">Starten</a>
</p>
