Iniciando em Struts2

andrecosta90 · Outubro 29, 2010, 1:07pm

Estou estudando a apostila fj21 da caelum. Estou começando a parte de struts 2 e nem consegui rodar aquele hello world ainda. Importei todos jars como explica a apostila, o xml tá igual lá e talz segue. Se puderem me explicar como proceder, com um passo-a-passao “mais detalhado”, pois estou com dificuldade.

Agradeço desde já!

XML

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

fj21-tarefas

index.html
index.htm
index.jsp

<filter>

</filter>


<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

[/code]

Action OlaMundoAction

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

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

public class OlaMundoAction {

@Action(value = "olaMundoStruts", results = { 
		@Result(location = "/WEB-INF//olaMundoStruts.jsp", name = "ok") })
		
public String execute() {
	System.out.println("Executando a lógica com Struts2");
	return "ok";
}

}[/code]

Olha só o que tá dando no log do tomcat:

Alguém pode ajudar aí ?

Obrigado!

andrecosta90 · Outubro 29, 2010, 6:51pm

E aí galera consegui resolver, tava faltando algumas libs, vou postar aqui o que eu fiz talvez alguém tenha futuramente o mesmo problema:

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)
log4j-1.2.14.jar
struts2-convention-plugin-x.x.x

e crie os arquivos struts.xml e log4j.xml na pasta src

log4j.xml

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

<log4j:configuration xmlns:log4j=“http://jakarta.apache.org/log4j/”>

<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
	<layout class="org.apache.log4j.PatternLayout">
		<param name="ConversionPattern" value="%d %-5p %c.%M:%L - %m%n" />
	</layout>
</appender>

<!-- specify the logging level for loggers from other libraries -->
<logger name="com.opensymphony">
	<level value="DEBUG" />
</logger>

<logger name="org.apache.struts2">
	<level value="DEBUG" />
</logger>

<!-- for all other loggers log only debug and above log messages -->
<root>
	<priority value="INFO" />
	<appender-ref ref="STDOUT" />
</root>

</log4j:configuration>
[/code]

struts.xml

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

<constant name="struts.devMode" value="true" />

<package name="basicstruts2" extends="struts-default">

	<action name="index">
		<result>/index.jsp</result>
	</action>

</package>

[/code]

OlaMundoAction.java

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

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

public class OlaMundoAction {

@Action(value = "olaMundoStruts", results = { 
		@Result(location = "/olaMundoStruts.jsp", name = "ok") }) //Corrigido aqui também
		
public String execute() {
	System.out.println("Executando a lógica com Struts2");
	return "ok";
}

}[/code]

JoaoMarques · Outubro 20, 2011, 9:27pm

Olha não precisa criar o struts.xml , nem o log …

Apenas muda essa linha :

    @Result(location = "/olaMundoStruts.jsp", name = "ok") })

Tira a “/”.

@Result(location = “olaMundoStruts.jsp”, name = “ok”) })

Testa e posta o resultado !

Continua aparecendo isso…

Quando eu coloco o filtro da erro. Tipo seu eu colocar http://localhost:8080/fj21-tarefas/ com o filtro no web.xml da erro(não aparece o index) e se eu colocar sem o filtro da tudo ok(aparece o index)…
Será que o poblrma não tá no filtro???
Eu coloquei o projeto no SkyDrive se alguem poder da uma olhada… vlw!!

JoaoMarques · Outubro 22, 2011, 8:21am

Bom , olhando seu projeto , achei o erro.

Está faltando jars.

asm-3.1.jar
asm-commons-3.1.jar

E é claro , que também está faltando algum jar de conexão com o banco de dados .

Caso você queira mexer com banco também , coloque o jar dele também .

E não esqueça de ADD no build path!

Abraço.
