You should be able to use the advice given earlier and just change your code
to, especially since you already seem to have a property called userList in
the class.
public List getUserList() {
if( userList != null ){
return list;
}
// Service Locator instance
IServiceLocator iSL = ServiceLocator.getInstance
().getIServiceLocator();
try {
// Search result list. Access to LDAP
list = iSL.getAuthorizationService().searchUsers(usc);
this.userList = list;
} catch (TimeOutConnectorException tex) {
tex.printStackTrace();
this.message = "Se excedió el tiempo máximo de
respuesta.Inténtelo de nuevo.";
} catch (Exception ex) {
ex.printStackTrace();
}
return userList;
}
