[Eclipse + Tomcat + Struts] lancement de Tomcat

j'ai installé :
Tomcat 4.1
Eclipse 2.1.3
et EasyStruts 0.64

j'ai évidement aussi installé le plugin tomcat pour Eclipse.
j'ai réalisé une mini appli strutspersonne sous éclipse mais lorsque je lance tomcat avec le plugin d'éclipse j'ai des messages d'erreurs que je ne saisie pas.
J'étudie toutes propositions de solution à mon problème, merci.
voici les exceptions levées :

j'ai oublié de préciser que j'utilise le JDK 1.5
personne n'a déjà rencontré ce problème ?

Bon, j'ai finalement réinstallé tomcat et ça marche maintenant.
Je pense que c'était dû au fait que j'avais installé lazlo sur tomcat car c'est la seule chose que j'avais modifié sur mon tomcat précédent.
