Run applet through ant from eclipse

I would like to run the applet in the build.xml file as follows:

<java classname="sun.applet.AppletViewer" classpath="${libraries}">
</java>

(at least that's how it works in netbeans)

but I get an error:

 [java] JVM args ignored when same JVM is used.
 [java] Could not find sun.applet.AppletViewer. Make sure you have it in your classpath

 [java] Java Result: -1

it seems that the classpath = "..." argument overrides the default eclipse-ant class path. unfortunately, I really need to specify an additional class path.

Try using the fork parameter.

<java classname="sun.applet.AppletViewer" classpath="${libraries}" fork="true">

Creates a new JVM process and launches your applet.

This works great:

<project default="test">

<target name="test">
    <java classname="sun.applet.AppletViewer">
        <arg value="http://java.sun.com/applets/jdk/1.4/demo/applets/BarChart/example1.html"/>
    </java>
</target>

</project>
