Runtime error when deploying a JavaFX application

Question

I'm trying to deploy a JavaFX app. The app I've been working on is fairly complex and includes several libraries. When I create a jnlp and try to run it I always get a "Runtime error. Click for details" message. Someone suggested I try doing just a simple Hello World app to see if it's an issue with the included libraries. I tried that and I still get the "Runtime error."

Here's the build.xml I'm trying to use.

    <project name="App" default="default" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">
        <taskdef resource="com/sun/javafx/tools/ant/antlib.xml"
             uri="javafx:com.sun.javafx.tools.ant"
             classpath="C:\Program Files\Java\jdk7\lib\ant-javafx.jar" />


        <target name="default">
        <fx:deploy width="600" height="400" outdir="${basedir}/dist" outfile="App">
            <fx:application name="App" mainClass="${javafx.main.class}"/>

            <fx:resources>
                <!-- include application jars -->
                <fx:fileset dir="${basedir}" includes="*.jar"/>
                <fx:fileset dir="${basedir}/lib" includes="*.jar"/> 
                <fx:fileset dir="${basedir}" includes="app.ini" />
                <fx:fileset dir="${basedir}/template" includes="*.template" />
            </fx:resources>

            <!-- request user level installation -->
            <fx:preferences install="false"/>
        </fx:deploy>
        </target>
    </project>

For the Hello World version I just removed the <fx:resources> section. I run both of them from inside eclipse as an ant task. They both created a dist folder in my project with a .jnlp and a .html file. I then click on the jnlp to run the app and see a small window that has the text, "Runtime error. Click for details.' I click it and get an error window that says, "The application failed to run. There was an error while executing the application. Click 'Details' for more information." I click the 'Details' button and see a Java Console with the following information (HelloWorld version):

I get a nearly identical error when I run the app I'm working on. I just uninstalled java and then reinstalled the latest SDK. That didn't do anything except may the app use the 64 bit JVM instead of a 32 bit JVM I had installed. The error message stayed the same.

Does anyone know what I'm doing wrong? Is my build script incorrect? Is there a better way to deploy? I don't have to have a jnlp so I'm open to any deploy method. I just need something I can run on a windows machine and possibly a mac.

I've tried googling my problem and I've searched StackOverflow and can't seem to find anything relevent. I might just be using the wrong search terms.

Any help would be greatly appreciated.

Thanks, Hardy

If you are using netbeans then Right Click on the Project and Go to Project Properties then to Libraries then click on Manage Platform then select the Default Javafx platform then go to JAVAFX tab and then change the JAVAFX SDK location to where your Java fx 2 sdk is and also similarly change the JAVAFX JRE. Hope this will solve your Problem.
