Titolo: [AIUTO] Tomcat 4.0.4 e jsp che non funzionato

Sto provando la seguente configurazione:
Redhat 7.3 + Tomcat 4.0.4 + j2sdk1.3.1   (ho provato anche il  j2sdk1.4.0_1 ma non cambia nulla)
ma quando tento di eseguire le jsp degli esempi mi da l'errore http  503 con descrizione: Servlet jsp is currently unavailable!
 
Invece le servlet funzionano bene!
Qualcuno può aiutarmi? Grazie
Di seguito inserisco il file di log di Tomcat ove si possono notare due eccezioni:
