VRaptor com JPA

Assuntos Gerais
#1

Bom dia, estou com uma dúvida. Acabei de concluir a apostila FJ28 da Caelum e está funcionando tudo corretamente. Quero usar VRaptor em um novo projeto que estou criando, porém antes estou tentando migrar a aplicação criada na FJ28 para JPA.

Estou usando JBOSS 7.1, e já adicionei no web.xml as configurações do VRaptor para utilizar jpa. Também já configurei o driver no JBoss como diz aqui (http://filosofisto.wordpress.com/2012/02/13/configurando-mysql-no-jboss-7-as/), porém, ainda estou com o erro abaixo, esqueci de algo?

10:24:32,175 INFO [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-4) HHH000102: Fetching database metadata 10:24:32,176 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-4) HHH000319: Could not get database metadata: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/fj28

#2

o jar do driver do mysql está no classpath?

#3

Está sim, até baixei esse (http://www.wbotelhos.com/2010/02/23/jpa-e-vraptor-3) projeto para testar e mesmo assim não rolou. Configurei o mysql nos modules do JBoss também.

#4

vc colocou no WEB-INF/lib da aplicação?

tentou colocar na pasta lib do jboss?

tentou configurar um DataSource no jboss e apontar direto pra ele?

  1. SIM

  2. Então, criei a seguinte estrutura: JBOSS_HOME/modules/com/mysql/main/ e dentro:
    mysql-connector-java-5.1.14-bin.jar
    module.xml

<module xmlns="urn:jboss:module:1.1" name="com.mysql"> <resources> <resource-root path="mysql-connector-java-5.1.14-bin.jar" /> </resources> <dependencies> <module name="javax.api" /> <module name="javax.transaction.api" /> <module name="javax.servlet.api" optional="true" /> </dependencies> </module>
E no standalone.xml configurei o driver:

<driver name="mysql" module="com.mysql"> <xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class> </driver>
persistence.xml

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

org.hibernate.ejb.HibernatePersistence 
	<properties>
		<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
		<property name="hibernate.connection.username" value="root" />
		<property name="hibernate.connection.password" value="" />
		<property name="hibernate.connection.url" value="jdbc:mysql://localhost/fj28" />
		<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />

		<property name="hibernate.hbm2ddl.auto" value="update" />
	</properties>
</persistence-unit>

[/code]

como vc fez a configuração do dataSource?

#7

Agora estou tentando sem o DS mesmo, mas já tentei com ele, você acha que pode ser isso? Pq pelo erro sei lá, parece que o JBoss 7 não está encontrado o jar que mapeei nos drivers, se eu usar o hibernate.cfg funciona normal, mas acho que nesse caso ele usa o jar do classpath e no JPA mesmo com o jar lá, ele deve estar tentando usar o driver que mapeei

#8

se estivesse usando o jar não ia dar o erro de no suitable driver…

seu jboss não está identificando esse jar por algum motivo…

tenta ver algum tutorial de como configurar um datasource mysql no jboss 7 e aponte no persistence.xml pra ele (via … ou )

#9

Vou dar uma olhada nisso e depois volto a postar aqui qualquer coisa. Obrigado Lucas

#10

Vc tem que criar um módulo.

Aqui mostra como criar módulos com postgres e mysql utilizando o JBoss: Aplicação Web Completa JSF EJB JPA JAAS.

#11

Pessoal, parece que consegui a parte do driver, pelo menos agora mudou o erro e acredito ser algo do VRaptor agora:

ainda é do hibernate… provavelmente vc tá usando @Cache sem ter habilitado

Obrigado pessoal, deu certo a parte do mysql.

Lucas, uma dúvida, escrevi os Daos com JPA e aparentemente tudo ok, porém qdo tento acessar algum método que utilizará o dao, ocorre o seguinte erro:

#14

vc tá usando o entityManagerCreator do VRaptor, certo?

dá uma olhada na inicialização do sistema, deve ter dado alguma exception.

#15

Esse entityManagerCreator é gerenciado pelo VRaptor apenas utilizando a configuração abaixo no web.xml ?

<context-param> <param-name>br.com.caelum.vraptor.provider</param-name> <param-value>br.com.caelum.vraptor.util.jpa.JPACustomProvider</param-value> </context-param>
No log do JBoss não deu nenhum erro não, esse erro ocorre qdo a aplicação tenta acessar o ProdutoDao.

Não consigo resolver, rsrs as configurações estão corretas certo?

web.xml:

[code]
br.com.caelum.vraptor.packages
br.com.caelum.vraptor.util.jpa

br.com.caelum.vraptor.provider br.com.caelum.vraptor.util.jpa.JPACustomProvider [/code] E meu DAO: [code]@Component public class ProdutoDao { 
private EntityManager manager;

public ProdutoDao(EntityManager manager) {
	this.manager = manager;
}

}[/code]

#17

Estranho…

em todo caso, tente trocar essa configuração do Provider por essa:

<context-param>
    <param-name>br.com.caelum.vraptor.packages</param-name>
    <param-value>br.com.caelum.vraptor.util.jpa</param-value>
</context-param>
#18

Retirei a parte do JPACustomProvider e deu o mesmo erro. Poderia ser algo com JAR faltando ou algo assim Lucas? Acredito que não né!? Estou quase perguntando se vc quer que eu zip o projeto e te mande, rsrsrs

PS: Tentei com CustomProvider igual explica na documentação do VRaptor mas tbm não rolou, se bem que no caso não teria diferença nenhuma. :confused:

#19

cara, é algum problema com a configuração que vc fez… deve estar escondido em alguma exception que acontece… a última que vc mandou tinha um NullPointer… geralmente só acontece isso quando deu erro na inicialização do EntityManagerCreator…

verifica se o nome do data source que vc tá usando tá direitinho e se não tem nenhuma outra exception relacionada…

#20

As configurações do web.xml são só essas mesmas certo? E o Dao está OK tbm ? To quebrando a cabeça faz tempo, rsrsrs, eu não entendi mto bem o erro, pelo que entendi, ele indica que o parametro no construtor do Dao estão errados, ou que falta alguma coisa, poderia me dar uma explicada melhor para eu dar uma pesquisada?

Quanto ao persistence.xml / standalone.xml do JBoss, já conferi e é isso mesmo, fiz um outro projeto para testar uma persistência com o MySQL no JBoss usando JPA e ta rolando certinho.
