Problema ao Salvar Dados com Entity Manager

Assuntos Gerais
#1

Bom dia pessoal. Estou tentando salvar umas informações aqui, mas não sei o que está acontecendo. O código para salvar é esse:

[code]public void importarDadosChuvas(){

	ChuvasDiarias chuvasDiarias = new ChuvasDiarias();
	ChuvaNegocio chuvaNegocio = new ChuvaNegocio();
	listachuvas = (List<Chuva>) chuvaNegocio.recuperaChuva(dataDaChuva);
	
	for(Chuva chuva : listachuvas){
		chuvasDiarias.setMaxima(chuva.getMaxima());
		chuvasDiarias.setDataChuva(chuva.getDataChuva());
		
		em.persist(chuvasDiarias);
	}
}[/code]

E recebo o seguinte erro:

#2

mostra o mapeamento dessa classe

#3

[code]@Entity
@Table(name=“chuvas_diarias”)
public class ChuvasDiarias implements Serializable{
private static final long serialVersionUID = 4676820501431156782L;

private Double maxima;
private Date dataChuva;

@Column(name="nu_maxima")
public Double getMaxima() {
	return maxima;
}

public void setMaxima(Double maxima) {
	this.maxima = maxima;
}

@Column(name="nu_data")
public Date getDataChuva() {
	return dataChuva;
}

public void setDataChuva(Date dataChuva) {
	this.dataChuva = dataChuva;
}

}[/code]

#4

dica: não coloque os “name” separados por espaços.
você verificou se sua entidade está declarada no persistence.xml?

#5

A entidade está mapeada corretamente no persistence.xml? Tenta verificar se o caminho completo está correto.

#6

Poderiam me dar uma exemplo desse mapeamento. Pois certa vez desenvolvi uma aplicação inteira sem precisar mapear. Deixei dessa forma:

[code]<?xml version="1.0" encoding="UTF-8"?>

org.hibernate.ejb.HibernatePersistence java:/TRProjectDatasource

[/code]

#7

faltou colocar

br.com.ana.tr.entidades.ChuvasDiarias

#8

Não esta faltando uma chave primária nessa entidade ai?

@Id
private Long id;

#9
#10

Não estou precisando ainda de chave primária e ela não é obrigatória. Depende do que estiver querendo fazer…

Coloquei o

Mas surgiu outro erro:

Está certo esse mapeamento?

Não está faltando estas anotações?

#12

Minhas configurações de banco estão em outro arquivo chamado de Data Source, pois estou usando JBoss Seam. Minha conexão está certa, o problema é esse mapeamento da classe.

#13

Alguem que não tenha ido almoçar por favor!!! rsrs Me ajudem!!

#14

Veja se existe algum “import” inválido ou diferente para a classe ChuvasDiarias.java
[javax.persistence.* ]

@javax.persistence.Entity is still mandatory, @org.hibernate.annotations.Entity is not a replacement.

#15

Os importes estão corretos

import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Table;
