Erro no Hibernate - org.hibernate.MappingException: Unknown entity

JavaEvangelist Membro desde: 10/12/2004 09:36:35 Mensagens: 330 Offline

Olá pessoal!

Estou com um probleminha que não estou conseguindo resolver. De antemão, estou utilizando JSF 1.2, Tomcat 6.0, Hibernate 3.3.0, o MySQL 5.1 e o RichFaces 3.3.0. No meu projeto eu estou utlizando a JPA e o Hibernate Annotations 3.4.

Pronto, vamos ao problema. Eu tenho configurados um arquivo web.xml (como segue abaixo) e dentro dele eu tenho um Filter, chamado de HibernateSessionFilter (como segue abaixo também).

-- web.xml:

</web-app>

-- HibernateSessionFilter (fiz o comentário do HibernateUtil para poder testar pelo ManagedBean):

package ##.###.######.#######.util;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class HibernateSessionFilter implements Filter {

@Override
	public void destroy() {
		// TODO Auto-generated method stub

}

@Override
	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain filterChain) throws IOException, ServletException {
		
		//HibernateUtil.openSession();
		
		try{
			
			//HibernateUtil.currentSession().beginTransaction();
			
			filterChain.doFilter( request, response );
			
			//HibernateUtil.currentSession().getTransaction().commit();
			
			
		}catch (Exception e) {
			
			throw new ServletException(e);
			
		}finally{
			
			//HibernateUtil.closeCurrentSession();
		}
	}

@Override
	public void init(FilterConfig arg0) throws ServletException {
		// TODO Auto-generated method stub

}

E dentro desse filtro eu faço uma chamada a uma outra classe chamada HibernateUtil, que segue abaixo.

-- HibernateUtil:

Aí eu tenho o meu entity, chamado de Department (segue abaixo) e tenho o meu ManagedBean, chamado de DepartmentMB.

-- Department:

package ##.###.######.#######.entity;

	@GeneratedValue( strategy = GenerationType.AUTO )
	private Long id;
	
	@Column( unique = true, nullable = false, length = 50 )
	private String description;
	
	@Column( nullable = false )
	private boolean status;

/**

	public Long getId() {
		return id;
	}

/**

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

/**

	 */
	public String getDescription() {
		return description;
	}

/**
	 * @param description the description to set
	 */
	public void setDescription(String description) {
		this.description = description;
	}

/**
	 * @return the status
	 */
	public boolean isStatus() {
		return status;
	}

/**
	 * @param status the status to set
	 */
	public void setStatus(boolean status) {
		this.status = status;
	}

/* (non-Javadoc)
	 * @see java.lang.Object#hashCode()
	 */
	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((id == null) ? 0 : id.hashCode());
		return result;
	}

/* (non-Javadoc)
	 * @see java.lang.Object#equals(java.lang.Object)
	 */
	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		final Department other = (Department) obj;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		return true;
	}
	
}

-- DepartmentMB:

package ##.###.######.#######.managedbeans;

import java.util.List;

import javax.faces.event.ActionEvent;

import org.hibernate.Session;

import ##.###.######.#######.dao.Dao;
import ##.###.######.#######.entity.Department;
import ##.###.######.#######.util.HibernateUtil;

public class DepartmentMB {

public Department department;
	
	public DepartmentMB() {
		department = new Department();
	}
	
	/**
	 * @return the department
	 */
	public Department getDepartment() {
		return department;
	}

/**
	 * @param department the department to set
	 */
	public void setDepartment(Department department) {
		this.department = department;
	}

public void save( ActionEvent event ) {
		
		System.out.println( "Saving Department: " + department.getDescription() );
		
		Session session = HibernateUtil.openSession();

HibernateUtil.currentSession().beginTransaction();
		
		Dao<Department> departmentDao = new Dao<Department>( session, Department.class );		
		
		departmentDao.save( department );
		
		HibernateUtil.currentSession().getTransaction().commit();
		HibernateUtil.closeCurrentSession();
		
		department = new Department();
	}
	
	public List<Department> getDepartments(){
		System.out.println("Loading departments...");
		Session session = HibernateUtil.openSession();
		Dao<Department> dao = new Dao<Department>( session, Department.class );
		return dao.list();
	}

}

Tenho, também, configurado o meu hibernate.cfg.xml e o meu faces-config.xml, que seguem abaixo.

Aí eu criei uma classe para gerar o meu banco de dados a partir das anotações chamada de DatabaseGenerator.

-- DatabaseGenerator:

E esta classe está funcionando perfeitamente. Consegui gerar uma tabela com o mesmo nome da entity.
E para testar a minha conexão com o banco de dados e as suas respectiva inserções e busca, eu criei uma classe chamada Stub. Executando esta classe, todas as informações funcionam, tanto a busca quanto a persistência.

-- Stub:

package ##.###.######.#######.main;

import java.util.List;

import org.hibernate.Session;

import ##.###.######.#######.dao.Dao;
import ##.###.######.#######.entity.Department;
import ##.###.######.#######.managedbeans.DepartmentMB;
import ##.###.######.#######.util.HibernateUtil;

public class Stub {

/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		DepartmentMB depto = new DepartmentMB();
		
		List<Department> listaDeptos = depto.getDepartments();
		
		for (Department department : listaDeptos) {
			System.out.println( department.getDescription() );
		}
		
		Department department = new Department();
		department.setId( new Long( 2 ) );
		department.setDescription( "Secretary" );
		department.setStatus( false );
		
		Session session = HibernateUtil.currentSession();
		HibernateUtil.currentSession().beginTransaction();
		
		Dao<Department> departmentDao = new Dao<Department>( session, Department.class );		
		
		departmentDao.merge( department );

HibernateUtil.currentSession().getTransaction().commit();
		HibernateUtil.closeCurrentSession();
	}

}

Ou seja, estou abrindo, nesse caso, a sessão do Hibernate na mão e fazendo o commit também na mão e tudo funciona perfeitamente. E abaixo tem o meu persistence.xml.

-- persistence.xml:

Então o grande problema é quando eu faço a chamada da minha página JSP para o meu ManagedBean (DepartmentMB) fazer a persistência do objeto Department, mais especificamente no método save, onde está estourando a exceção:

Bem, acho que consegui mostrar todos os possíveis arquivos que possam estar com problemas. Se alguém tiver uma luz, eu agradeço. Já fiz alguns testes e nenhum resultado positivo.

O que é mais estranho é que a nível de aplicação "offline" tudo funciona, mas quando faço a aplicação rodar "online" está dando erros. Será que esse erro está acontecendo devido ao servidor de aplicação ser o Tomcat? Para rodar o Hibernate eu precisaria de um servidor de aplicação como o JBoss?

Enfim, estou meio perdido e não entendo porque não está funcionando.

Ficarei no aguardo.

Abraço e de antemão, obrigado!

Cara posso estar enganado mas eu senti falta na sua classe @Entity a tag @Table apontado para a tabela do banco de dados.
Onde vc faz essa relação ?

/peace.

Eugenio,

Essa anotação da Table não é necessária. Só seria necessário se o nome da tabela fosse diferente da sua entity.
E mesmo assim, eu mencionei que eu consegui fazer funcionar rodando a aplicação através da classe Stub.
Ou seja, não é problema com a entity. Parece ser algum problema de configuração.
Mesmo assim, obrigado.
