You need to get the map to an available context

//in your scriplet or action servlet

Map map = new HashMap();
map.put("nombre", ((prueba)muestraProfesores).getNombre());        
map.put("apellido1",((prueba)muestraProfesores).getApellido1());        
map.put("apellido2",((prueba)muestraProfesores).getApellido2());

request.setAttribute("myMap",map); // or better in pageContext

//jsp

<logic:iterate id="foo" name="map" scope="request">
<html:link name="foo" .... play with the attributes an you'll work it 
out

Cheers mark
