corriendo a través del applet de hormigas de Eclipse

me gustaría lanzar un applet en un build.xml así:corriendo a través del applet de hormigas de Eclipse

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

(al menos así es como funciona en NetBeans)

pero me da la mensaje de 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

parece que la ruta de clase = "..." argumento anula la ruta de clase por defecto Eclipse-ant. lamentablemente, realmente necesito especificar un classpath adicional.

I _guess_ tiene que agregar tools.jar a su classpath –

@Tim: he agregado rt.jar al classpath, pero luego obtengo esta excepción: java.lang.IllegalAccessError: intenté acceder a la clase sun.applet .AppletMessageHandler de la clase sun.applet.AppletViewer – clamp

intente extraer el argumento de ruta de clase (y el argumento JVM), entonces se toma la ruta de clases que se inició con –

Trate de usar el parámetro tenedor.

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

Creará un nuevo proceso de JVM y ejecutará su applet.

No debería necesitar realmente a la mesa con el fin de utilizar nombre de clase + ruta de clase. – Grodriguez

gracias, parece que el applet necesita tener su propia máquina virtual para poder tomar las variables classpath correctamente – clamp

Esto funciona bien:

<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>

sí que funciona porque no hay ninguna ruta de clase = "" argumento. Desafortunadamente, realmente necesito especificarlo con algunas variables. – clamp
