Exception do Spring Framework

Boaa Tarde Galera!

Estou aqui apelando por meu ultimo recurso. Estou desenvolvendo um trabalho para a ferramenta TIDIA-AE que eh uma ferramenta derivada do Sakai Project.

Acontece que ela usa o Spring Framework e eu ainda estou apanhando com os beans e tals. Estou com uma exception no ApplicationContext.xml que eu não consigo instanciar a meleca do DominioService.

Não sei quais códigos devo postar, então vai uma parte da Exception (Ela está ocorrendo no tomcat, pois estou fazendo deploy e testando, mas não consigo sair dessa exception que ocorre no tomcat no log do statup.bat):

ERROR: Exception sending context initialized event to listener instance of class
org.sakaiproject.util.ContextLoaderListenet (2012-02-08 20:03:26,356 ContainerB
ackgroundProcessor[StandardEngine[Catalina]]_org.apache.catalina.core.ContainerBase.
[Catalina].[localhost].[/selfregulationsystem-tool])
org.springframework.beans.factory.BeanCreationException: Error Creating bean with
name 'masterBean' defined in ServletContext resource [/WEB-INF/applicationContext.xml]:
Instatiation of bean failed: nested exception is java.lang.NoClassDefFoundError: 
br/edu/ufabc/srs/service/DominioService
Caused By:
java.lang.NoClassDefFoundError: br/edu/ufabc/srs/service/DominioService
	at java.lang.Class.getDeclaredMethods0(Native Method)

Esse aqui é meu ApplicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
	"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
	<bean id="masterBean" class="br.edu.ufabc.srs.bean.MasterBean">
		<property name="sakaiService" ref="br.edu.ufabc.srs.service.SakaiService" />
		<property name="dominioService" ref="br.edu.ufabc.srs.service.DominioService" />
	</bean>
</beans>

Por fim, meu MasterBean:

package br.edu.ufabc.srs.bean;

import java.sql.SQLException;
import java.util.ArrayList;

import br.edu.ufabc.srs.model.Dominio;
import br.edu.ufabc.srs.service.DominioService;
import br.edu.ufabc.srs.service.SakaiService;

public class MasterBean {

	private SakaiService sakaiService;
	private DominioService dominioService;

	public void setSakaiService(SakaiService sakaiService) {
		this.sakaiService = sakaiService;
	}

	public void setDominioService(DominioService dominioService) {
		this.dominioService = dominioService;
	}

	public SakaiService getSakaiService() {
		return sakaiService;
	}

	public ArrayList<Dominio> pegarDominios() throws SQLException {
		return this.dominioService.buscarTodosDominios();
	}

}

Agradeço a atenção de todos! Estou ficando louco com esse erro que eu nao consigo resolver. Já pesquisei de tudo.

Vc está utilizando dois projetos separados?

Um só com modelo e outro apenas com a view?

Estou utilizando Maven no projeto divididos nos seguintes módulos:

  • API
  • IMPL
  • PACK
  • TOOL

O tool é onde fica a parte web e ele implementa a API que tem as interfaces que eu estou utilizando. O Negócios é que o pom.xml jah esta declarando a dependencia, tanto que o SakaiService ele não da erro, não sei porque. =[

Vc faz o deploy dentro de um EAR? WAR/jar separados?

Só para tirar uma dúvida bem idiota, verifica se essas classes estão indo na hora do deploy.

iuoyo
iuoyo

eu ainda nao domino o maven completamente, mas nao vejo nenhum EAR e nem na pasta raiz. Ele compila e jah faz deploy direto no tomcat com arquivo .war

na pasta raiz ele produz uma pasta bin que contem toda as classes compiladas. assim como o projeto web e as inclusões do PACK.

Hebert_Coelho

No arquivo WAR você consegue ver essas classes que estão faltando?

Hebert_Coelho
Hebert_Coelho

Eu imagino que o problema seja: mesmo que você tenha adicionado no mavem que as classes são dependência, pode ser que elas não estão sendo empacotadas por falta de alguma configuração extra.

É, eu abri o war e na WEB-INF na pasta /lib não tem nenhuma das bibliotecas e nem na pasta classes.

Estranho porque deveria dar problema ao instanciar o SakaiService não?

Preciso dar uma olhada na configuração do Maven.

Eu imaginei que era classe faltando por empacotamento. Agora, oq tinha que fazer ou não, aí não sei te falar.
Tenho muito q aprender de Maven e Spring. [=

Coloca sua configuração do mavem aí que talvez outra pessoa possa te ajudar.

realmente eh complicado maven, aqui tem arquivos project.xml, é do maven? Segue meus pom.xml
