Retrieving session data in remote objects with FlexContext.getFlexSession().getAttribute(myName) doesn´t work

Here is a jsp page (fww_prueba_ale.jsp) that references a swf (compiled from sessionDataManagerCaller.mxml) that only makes a call to a Remote Object (SessionDataManager.java) that try to obtain information from the session. In the jsp, i set a session attribute myName, with the value Paolo and i print it and the session ID. In the remote object, i try to get the value of that attribute, but it is null. The session ID is not the same either.

public class SessionDataManager
{
public SessionDataManager()
{
System.out.println("Constructor de SessionDataManager");
}

public Object[] manipulateSessionData()
{

System.out.println("EN getManipulateSessionData()");

HttpServletRequest req = FlexContext.getHttpRequest();
FlexSession flxSession = FlexContext.getFlexSession();

System.out.println("FlexContext.getHttpRequest().getSession().getId(): "+
FlexContext.getHttpRequest().getSession().getId());

System.out.println("FlexContext.getFlexSession().getId(): "+
FlexContext.getFlexSession().getId());

System.out.println("FlexContext.getFlexSession().getAttribute(myName): "+
FlexContext.getFlexSession().getAttribute("myName"));

System.out.println("FlexContext.getHttpRequest().getSession().getAttri bute(myName): "+
FlexContext.getHttpRequest().getSession().getAttribute("myName"));


ArrayList list=new ArrayList();
return list.toArray();

}

fww_prueba_ale.jsp

<%
request.getSession().setAttribute("myName", "Paolo");
System.out.println("request.getSession().getId(): "+request.getSession().getId());
System.out.println("request.getSession().getAttribute(myName): "+request.getSession().getAttribute("myName"));

Here is the output
