[Gvsig_desarrolladores] ayuda llamar GeoprocessManagerExtension

[Andres Felipe jama]

reciban cordial saludo señores desarrolladores.
ya he logrado llamar la extensión AddEventTheme desde un botón de una extensión propia de la siguiente manera 
AddEventThemeExtension addEventTheme =(AddEventThemeExtension)PluginServices.getExtension(AddEventThemeExtension.class); 			addEventTheme.execute("");
y me funciona correctamente gracias a la ayuda de ustedes  y del señor Joaquin del cerro, Pero ahora estoy tratando de llamar la extensión GeoprocessManagerExtension
me compila correctamente con apache ant, pero cuando pico o doy clic en el botón y tengo una ventana activa con capas me saca el siguiente error
 así es como llamo la función de la clase en mi boton :GeoprocessManagerExtension geo =(GeoprocessManagerExtension)PluginServices.getExtension(GeoprocessManagerExtension.class); 			geo.execute("");
por favor si saben como corregir ese error les estaré muy agradecido muchísimas gracias y un prospero año nuevo!!
