Tomcat + Eclipse + Windows Vista = Nada Funciona.

Bom pessoal, sempre usei netbeans. Mas agora tenho que usar o Eclipse.
Então baixei o jdk instalei e setei ele no java_home.
Baixei o Jee + SDK e instalei.
Baixei o Tomcat e descompactei na raiz do meu HD e o eclipse colocei dentro de uma pasta c:\Desen\Eclipse, e meu Workspace está em c:\Desenv\MeuWorkspace.
Por fora, eu starto e abro o tomcat numa boa.
E por dentro do Eclipse ele starta se tiver sem nenhuma aplicação dentro.
Mas se eu colocar alguma aplicação e starto (sem executar a aplicação, só startar o tomcat mesmo) ele me dá uma série de erros que não consigo resolver.
