[size=7]Boa tarde, Pessoal !
sou novo no desenvolvimento Java e estou fazendo uma pequena aplicação, ao criar um novo evento para chamar outro Form esta dando o seguinte erro:

Será que alguém poderia dar uma força.

#2

Detalhe, o mesmo processo que criei para um outro form, deu certo.
Fiz a mesma coisa no outro e não funcionou.[size=9][/size]

#3

O problema está no arquivo br.com.siscom.view.CartaoView.java, na linha 46. Poste o trecho aqui.

PS: essa fonte minúscula está horrível de ler…

#4

Esta é a linha 46

query = java.beans.Beans.isDesignTime() ? null : entityManager.createQuery(“SELECT c FROM Cartao c”);

Valeu pela força.

#5

Você poderia explicar a sua consulta SQL? O que ela deveria fazer? E o que ela faz?

#6

Existem 3 campos na base, na verdade algo bem simples.

SELECT COD_CARTAO,NOME_CARTAO, TAXA_CARTAO FROM CARTAO

Somente isso, mas não esta funcionando.

Fiz da forma antiga em uma outra tabela e funcionou.

#7

Use o nome do campo e o nome da tabela completos (respeitando capitalização). Por exemplo:

SELECT Cod_Cartao FROM Cartao

A capitalização dependerá de como você criou a tabela. Após isso verifique se o problema persiste.

#8

Fiz esta alteração em Inspetor Query, coloquei da seguinte forma e também não funcionou:
SELECT c.COD_CARTAO,c.NOME_CARTAO, c.TAXA_CARTAO FROM Cartao c
SELECT COD_CARTAO,NOME_CARTAO,TAXA_CARTAO FROM Cartao
select cod_cartao, nome_cartao, taxa_cartao from cartao

Nenhum destes esta funcionado

Esta dando o seguinte erro no ultimo:
