No sirve localhost

[Thrashmilenio]

Hola a todos, cuando corro mi jsp en la web me sale el siguiente error:


ERROR
The requested URL could not be retrieved

--------------------------------------------------------------------------------

The following error was encountered while trying to retrieve the URL: http://localhost:8080/ConvenioSed/

Connection to 127.0.0.1 failed.

The system returned: (111) Connection refused

The remote host or network may be down. Please try the request again.

Your cache administrator is webmaster.

ya intente modificar en C:\WINDOWS\system32\drivers\etc\hosts la parte de:

127.0.0.1 localhost

por:

127.0.0.1 localhost
::80 localhost

y nada!!!!

creo que es problema de glassfish, pero la verdad no se como solucinarlo.

Le agradezco su colaboracion
