Problemas: passando do tomcat 5.5 para o 6.0 [AJUDA]

Front-end
#1

Pessoal eu fiz uma aplicação no eclipse usando o tomcat 5.5 resolvi mudar a versao do tomcat da minha maquina para 6.0. A grande maioria das aplicacoes que estavam funcionando no 5.5 continuaram funcionando no 6.0, mas teve uma aplicacao que quando eu coloco para rodar no 5.5 ela funciona normalmente e quando eu coloco para rodar no 6.0 ele soh mostra uma pagina em branco …

alguem tem alguma idéia do que pode ser?

cara eu consegui ajeitar o erro da pagina em branco, agora to com outro erro … acredito que seja conflito entre as versoes do jsp ou servlet que sao diferentes nas duas versoes do tomcat. vou colocar o codigo da pagina .jsp e o codigo do erro quem sabe vocese me ajudam.
