Problema com anotações em Struts 2 [ RESOLVIDO ]

Front-end
#21

Pela mensagem de erro no log estás com problema no “javassist”. Teve um colega neste mesmo tópico que passou por isso e resolveu.

#22

Eu dei uma olhada, não possui nenhum tipo desse JAR. =S

Dei um clean no projeto, fechei e abri o Eclipse.

#23

Então… falta incluir esse jar.
javassist-x.jar
(onde x é a versão da biblioteca)

#24

Então, dentro do Struts2 tem esse Jar. Algum outro deve pedir este…

Adicionei lá, mas mesmo assim, continua o mesmo erro:

#25

Não, não é o mesmo erro.

Agora o erro é
java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

Você está com versão errada ou com jar faltando da biblioteca ASM.

#26

Perfeito cara!

Daquela lista que você passou, tive que adicionar dois JAR’s

asm-3.1.jar
javassist-3.11.0.GA.jar

creio que eles sejam necessários também!

Po muito obrigado cara! Valeu mesmo!

Só tenho uma dúvida:

estou mexendo no olaMundoStruts.jsp que se encontra em: WebContent/WEB-INF/content

só que toda vez que o salvo pede para reiniciar o TomCat, é isso mesmo?

#27

Sim, o Eclipse fica fazendo isso :frowning:

#28

Bah que coisa… creio que seja um pouco complicado para uma grande organização…

Mas de boa, da de aprender direitinho.

Cara, tens alguma dica de apostila para Struts e hibernate para mim?

Valeu cara, valeu mesmo!

#29

É só desabilitar o build automático do projeto. Assim você pede pro Eclipse fazer o build só quando quiser.

#30

Além da apostila da Caelum, só on-line:
O site www.roseindia.net possui ótimos materiais de ambos.

#31

Po Beleza
Valeu pela dica ai cara das apostilas

e pela grande ajuda nos problemas relatados!

Graças a pessoas como você que o GUJ é tão bom!

Valeu mesmo cara.
Agora vou dormir que amanhã é cedo trabalhar hiueaheiuaheauei.

Se cuida cara, boa noite.

#32

Po rapaziada,

estou com outro erro estranho aqui.
Seguinte.

Tenho na pasta: WebContent o jsp: formulario-tarefas.jsp.

[code]<%@ page language=“java” contentType=“text/html; charset=ISO-8859-1”
pageEncoding=“ISO-8859-1”%>

Insert title here

Adicionar tarefas

Descrição:

[/code]

Tenho na pasta WebContent/WEB-INF/content o jsp: tarefa-adicionada.jsp (Que só exibe mensagem de tarefa adicionada)

No scr, na pasta das actions tenho a seguinte Action: AdicionaTarefasAction.java

[code]package br.com.caelum.tarefas.action;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;

import br.com.caelum.tarefas.DAO.TarefaDAO;
import br.com.caelum.tarefas.beans.Tarefa;

public class AdicionaTarefasAction {

private Tarefa tarefa;

@Action(value="adicionaTarefa", results = {
@Result(name="ok", location="tarefa-adicionada.jsp")
})

public String execute() {
	new TarefaDAO().add(tarefa);
	System.out.println("Entrou método execute");
	return "ok";
}

public Tarefa getTarefa() {
	return tarefa;
}

public void setTarefa(Tarefa tarefa) {
	this.tarefa = tarefa;
}

}[/code]

Porém quando acesso o formulario-tarefas.jsp através de http://localhost:8080/Tarefa/formulario-tarefas.jsp

Não redireciona para a pagina tarefa-adicionada.jsp.

Dá o seguinte log: “GRAVE: Unable to read class [br.com.caelum.tarefas.action.AdicionaTarefasAction]
java.lang.NoClassDefFoundError: org/objectweb/asm/commons/EmptyVisitor”
além de outros.

Ainda é problema de biblioteca. Da ASM no caso.

Tente gerenciar suas bibliotecas via Maven, evita toda essa dor de cabeça com os jars.

#34

Boa noite amigo,

Já havia percebido isso e colei outra biblioteca ASM na LIB e deu certo.

Me fale mais sobre este Maven, o que ele seria? É simples de utilizar?É de grande utilização no mercado?

Muito obrigado pelas ajudas!

Um problema comum quando iniciando struts 2 é saber quais os jars necessários pq não existe um arquivo readme que diz quais são os jars básicos, pelo menos eu nunca vi.

De acordo com Getting Started do Struts os jars básicos são os seguintes:

Now that we know we have a working Java web application, lets add the minimal required Struts 2 framework Jar files to our web application’s class path. We’ll copy these Jar files from the lib folder of the Struts 2 download to the WEB-INF/lib folder in our web application.

Find and copy to WEB-INF\lib these files (note X.X.X.X.jar refers to the version number):

commons-fileupload-X.X.X.jar
commons-io-X.X.X.jar
commons-logging-X.X.X.jar
commons-logging-api.X.X.jar
freemarker-X.X.X.jar
ognl-X.X.X.jar
struts2-core-X.X.X.X.jar
xwork-core-X.X.X.jar
javassist-3.7.ga.jar (new for Struts versions 2.2.1 and higher)

Agora, quando vamos utilizar as anotações é preciso também adicionar no classpath o jar chamado struts2-convention-plugin-X.X.X.X
