[RESOLVIDO] localhost funciona, na web aparece: Cant instantiate class:

Olá, tenho um projeto no meu netbeans que funciona normalmente localhost connectando com o banco de dados na web…

porém quando eu faço deploy desse projeto em um servidor na web, ele da erro:

será que falta alguma lib no servidor?
obs.: estou usando um servidor VPS com a mesma versão do tomcat.
