Pesssoal,

to tentando mostrar um hello world em uma pagina web a partir de uma base MySQL.

Só que dá a seguinte excessão:

Eu tenho uma classe jUnit que roda legal. O problema dá quando eu tento acessar o dao direto no controller.

A seguir meus fontes:

package br.com.rodrigomelo.melofogolin.domain;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity(name = "impostos")
public class Imposto {
	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private long id;

	private String nome;

	private String acronimo;

	private float aliquota;

	public long getId() {
		return id;
	}

	public void setId(long id) {
		this.id = id;
	}

	public String getNome() {
		return nome;
	}

	public void setNome(String nome) {
		this.nome = nome;
	}

	public String getAcronimo() {
		return acronimo;
	}

	public void setAcronimo(String acronimo) {
		this.acronimo = acronimo;
	}

	public float getAliquota() {
		return aliquota;
	}

	public void setAliquota(float aliquota) {
		this.aliquota = aliquota;
	}
}

Unknown entity bean class: class br.com.rodrigomelo.melofogolin.domain.Imposto, please verify that this class has been marked with the @Entity annotation.; nested exception is java.lang.IllegalArgumentException: Unknown entity
bean class:#
@Entity(name = “impostos”)

public class Imposto {

return getJpaTemplate().find(“select i from impostos i where i.acronimo = ?1”, acronimo);

seguinte eu nao sei se estou certo mas eu acho que é isso:
na consulta deve ser:
return getJpaTemplate().find(“select i from Imposto i where i.acronimo = ?1”, acronimo);
pq voce deve usar o nome da classe. Quer dizer se este metodo find for HQL.

espero que ajude flwssss

Acho que lá é o nome da tabela mesmo.

Mas eu consegui resolver o problema já. :)

No applicationContext fiz a seguinte alteracao:

<property name="loadTimeWeaver">
			<bean
				class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
		</property>

De:
org.springframework.instrument.classloading.SimpleLoadTimeWeaver

Para:
org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver

E acrescentei o seguinte parametro ao subir o tomcat:
-javaagent:caminho/para/o/spring-agent.jar

Encontrei isso na referencia do Spring, mas nao encontro o link agora.

Mas valeu aí Vanderbill!
