FX XML extension

When using the JNLP, you create a JNLP file. Here is an example:

    <?xml version="1.0" encoding="UTF-8"?>
    <jnlp spec="1.0+" codebase="" href="">
      <information>
        <title>Sample/title>
        <vendor>The Sample Vendor</vendor>
        <icon href="sample-icon.jpg"/>
        <offline-allowed/>
     </information>
     <resources>
       <!-- Application Resources -->
       <j2se version="1.6+"  
        href="http://java.sun.com/products/autodl/j2se"/>
       <jar href="Sample-Set.jar" main="true" />
     </resources>
     <application-desc
       name="Sample Application"
       main-class="com.vendor.SampleApplication" 
       width="800" 
       height="500">
       <argument>Arg1</argument>
       <argument>Arg2</argument>
       <argument>Arg3</argument>
     </application-desc>
     <update check="background"/>
    </jnlp>

Two changes have been made to the <application-desc> element. First, the optional type attribute has been added so the type of application can be annotated. The default type is Java, so if your program is a Java app, you need not include the type attribute. Alternatively, you can specify Java as your type as follows:

    <application-desc 
      name="Another Sample Application"
      type="Java" main-class="com.vendor.SampleApplication2" 
      width="800" 
      height="500">
      <argument>Arg1</argument>
      <argument>Arg2</argument>
      <argument>Arg3</argument>
    </application-desc>

We can indicate other application types to include JavaFX as shown here:

    <application-desc 
      name="A Great JavaFX Application"
      type="JavaFX" main-class="com.vendor.GreatJavaFXApplication" 
      width="800" 
      height="500">
      <argument>Arg1</argument>
      <argument>Arg2</argument>
      <argument>Arg3</argument>
    </application-desc>

The second change to the <application-desc> element in Java 9 is the addition of the param sub-element. This allows us to provide the name of parameters along with their value using the value attribute. Here is an example of how an <application-desc> element of a JNLP file looks with the param sub-element and the value attribute included. This example shows three sets of parameters:

    <application-desc
      name="My JRuby Application"
      type="JRuby"
      main-class="com.vendor.JRubyApplication" 
      width="800" 
      height="500">
      <argument>Arg1</argument>
      <argument>Arg2</argument>
      <argument>Arg3</argument>
      <param name="Parameter1" value="Value1"/>
      <param name="Parameter2" value="Value2"/>
      <param name="Parameter3" value="Value3"/>
    </application-desc>
