useBean falhando

Ola dres… estou a fazer um site em jsp usando o eclipse… e estou com o seguinte problema… . meu useBean não reconhece o atributo class… verifiquei o nome da minha classe… e esta correto, com seu pacote declarado. Verifiquei se no class="" consta todo o caminho ate a classe inclusive seu respectivo pacote… e sim, consta. Mas por alguma razão o erro persiste … por favor. Alguem pode me ajudar??

eis o meu jsp.
