Boa noite pessoal,

Estive desenvolvendo um projeto com VRaptor e ao publicar ele no servidor de aplicação (Apache Tomcat) tive o seguinte problema.

log4j:WARN No appenders could be found for logger (br.com.caelum.vraptor.config.BasicConfiguration).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Mar 12, 2013 8:07:33 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Error filterStart
Mar 12, 2013 8:07:33 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/IPMan2] startup failed due to previous errors

Alguma luz ?

Agradeço desde já

Abraços !

Você habilitou o LOG4J na sua aplicação? Se sim, habilita ele para a gente ver o que o tomcat tem a dizer.

Desculpa a ignorância mas Como eu faço isso ?

Rafael_Guerreiro

É bem simples: primeiro crie um arquivo chamado log4j.properties na pasta src do seu projeto.

depois, adicione algumas configurações (modifique para o seu projeto)

log4j.rootLogger=WARN,consoleAppender
# Troque o pacote
log4j.logger.seu.pacote.raiz=DEBUG,dailyFile

log4j.appender.consoleAppender=org.apache.log4j.ConsoleAppender
log4j.appender.consoleAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.consoleAppender.layout.ConversionPattern=%-2d{dd/MM/yy HH:mm:ss} %5p %c:%L%n%m%n

log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppender
# Troque o nome do arquivo
log4j.appender.dailyFile.File=${catalina.home}/logs/NOME_DO_SEU_ARQUIVO.log
log4j.appender.dailyFile.DatePattern='.'yyyy-MM-dd
log4j.appender.dailyFile.layout=org.apache.log4j.PatternLayout
log4j.appender.dailyFile.layout.ConversionPattern=%-2d{dd/MM/yy HH:mm:ss} %5p %c:%L%n%m%n

Depois você pode pesquisar mais sobre essas configurações e ai você pode modificá-las ao seu gosto.

alguma idéia do que seja ?

Lucas_Cavalcanti

dá um clean no projeto e no servidor e tenta de novo…

esse log não mostra o que seria o erro…

talvez isso:
17638 HHH000223: Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/. Use namespace http://www.hibernate.org/dtd/ instead. Refer to Hibernate 3.6 Migration Guide!

sugere que pode estar dando problemas no mapeamento do hibernate

Algo que possa ta errado ai ?
Já dei um clean e ainda a mesma coisa.
To usando Hibernate 4 … com o plugin lá…algum problema de versão ?

Abraços !

esse erro não é por causa do log… tem alguma coisa errada no deploy da aplicação…

talvez o web.xml esteja mal formado, ou tenha um dado errado, ou qqer outra coisa do tipo.

o cabeçalho do xml tá apontando pra versão 2.5 do servlet:

xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

e pra versão 3.0

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

ao mesmo tempo, por isso que não está subindo.

Se o seu servidor for compatível com servlet 3.0, mude tudo pra 3_0, senão mude tudo pra 2_5

No apache ainda o erro

FAIL - Application at context path /IPMan2 could not be started

O deploy vai porém na hora de da um start na aplicação ocorre esse erro

Lucas_Cavalcanti

ainda sobrou um:

version="3.0"

na dúvida, pede pro eclipse gerar o web.xml e altera o que for preciso.

Se eu tiro os filtros do web.xml ele faz o deploy ok e starta a aplicação … porém não resolve nenhuma das urls

ele não dá nenhuma exception se vc coloca o filtro do VRaptor?

aparece esse SEVERE: Error filterStart com os filtros no web.xml …
Se comento eles ele faz o deploy e já starta a aplicação … porém não abre página nenhuma

Se vc ler o erro vc consegue ver o que está acontecendo:

Unable to load class [ ccc.cefetmg.ipman.model.Department] declared in Hibernate configuration <mapping/> entry

…

Caused by: java.lang.ClassNotFoundException: ccc.cefetmg.ipman.model.Department

ou seja, essa classe não existe… deve estar com o nome ou o pacote errado, no mapeamento do hibernate.

vitor.morales

Mas ta perfeito … tanto que localmente eu consigo rodar

essa classe está no war/jar/ear deployado no servidor?

Cara… eu fiz uma loucura aqui

Eu gerei um .war na mão … daí copie desse war pro war que o netbeans gera as classes do modelo que tavam faltando … ai deu tudo certo … só que to sem acesso ao banco aqui ai ta dando alguns erros.

Mas gostaria de saber pq o netbeans ao construir o projeto e criar o war não ta fazendo isso certo

mas vc gera um war ou coisa do tipo?
