Estou tentando rodar um código no Eclipse que fiz de um ecommerce, mas toda vez que tento fazer um insert, retorna um erro 500. Já importei o servlet-api.jar no projeto, porém o código da servlet continuava com erro, então tentei baixar o javax.servlet.jar na internet. O erro da servlet sumiu, porém o código continua não rodando. O que posso fazer?
Segue log do console:
HTTP Status 500 – Internal Server Error

Description The server encountered an unexpected condition that prevented it from fulfilling the request.
