Problema com JPA para pegar uma string do banco

Bom dia pessoal!

Bom estou com o seguinte problema com o JPA, quando ele vai pegar na minha base de dado um campo que ele está como estring ele tenta pegar como inteiro, não consigo entender porque ele está fazendo isso, o mapeamento foi gerado no netbeans, e está de acordo. o projeto está sendo desenvolvido no eclipse.

quando tento executar essa consulta no servidor, estou usando JBoss 4.2.2.GA.

imprime o seguinte no console
