VRaptor3 + Tiles2 (Runtime Composition in JSP pages)

Assuntos Gerais
#21

Estou utilizando os seguintes jars:

tiles-api-2.2.2.jar
tiles-core-2.2.2.jar
tiles-jsp-2.2.2.jar
tiles-servlet-2.2.2.jar

Devo utilizar outra versão?!

#22

esses jars estão na pasta WEB-INF/lib?

#23

Estão sim.

Verifiquei aqui e estava faltando o tiles-template-2.2.2.jar.

Problema foi resolvido agora.

#24

Pessoal, estou fazendo uma POC (prova de conceito) com VRaptor 3.2 e Tiles 2.2.0 no Tomcat v7.0.6. Estou usando Ivy para gerenciar as dependências. Tive problemas na hora de subir a aplicação.

Qual o problema?

Depois de algumas pesquisadas, vi neste post http://www.guj.com.br/java/224562-configurando-vraptor-320 uma luz para a solução, e, consegui resolver com a configuração abaixo:

Usei a versão 2.1.0 do Tiles excluindo “jcl-over-slf4j” e funcionou perfeitamente:

	<dependencies>
		<dependency org="br.com.caelum" name="vraptor" rev="3.2.0" conf="default" />
		<dependency org="org.apache.tiles" name="tiles-jsp" rev="2.1.0" conf="default">
			<exclude module="jcl-over-slf4j" />
		</dependency>
	</dependencies>

Não sei se é a melhor forma para isso, alguém pode me ajudar a resolver da forma correta funcionar com VRaptor 3 e Tiles 2.2?

Abraço!

#25

Se você usar o jcl-over-slf4j deve remover o commons-logging das dependencias, pois um conflita com o outro.

#26

o slf4j é justamente um módulo para escolher qual engine de logging vc vai usar.

é perfeitamente válido vc substituir o logging que quer usar, no caso trocando o jcl pelo do vraptor, que é o log4j

#27

Fala Garcia, isso não resolveu o problema :frowning:

Você quis dizer dessa forma?

	<dependencies>
		<dependency org="br.com.caelum" name="vraptor" rev="3.2.0" conf="default">
			<exclude module="commons-logging" />
		</dependency>
		<dependency org="org.apache.tiles" name="tiles-jsp" rev="2.2.0" conf="default" />
	</dependencies>

Alguém ainda na escuta? :slight_smile:

Abraço!

#28

sem o jcl-over-slf4j o tiles não funciona?

acho melhor excluir esse modulo

#29

Um outro problema que ocorre mas funciona é o seguinte:

Com essa configuração de dependências:

	<dependencies>
		<dependency org="br.com.caelum" name="vraptor" rev="3.2.0" conf="default" />
		<dependency org="org.apache.tiles" name="tiles-jsp" rev="2.1.0" conf="default">
			<exclude module="jcl-over-slf4j" />
		</dependency>
	</dependencies>

Funciona, só que dá um erro neste instante:

Porque?

Abraço!

#30

pq o spring tá tentando usar o slf4j com o commons-logging…

geralmente dá pra ignorar esse erro, no pior dos casos vc não vai ver os logs do spring

#31

Eu não conheço muito do Ivy, mas quais as dependencias você tem aí? Dá para postar o trecho do arquivo onde você define as dependencias?

O que está acontecendo aí é que tu tens declarado classes que conflitam entre sí. No site do SLF4J há uma documentação que explica bem o que é cada módulo. No seu caso o jcl-over-slf4j substitui o commons-logging, assim como o jul-over-slf4j substitui o Java Logging, e o mesmo para o log4j-over-slf4j que substitui o log4j.

#32

Hum… entendi.

ivy.xml:

<ivy-module version="2.0">

		<conf name="default" description="dependencies used for compile" />
	</configurations>

#33

O problema está sendo aqui, tem duas libs do commons-logging, sendo que além disso tem o jcl-over-slf4j.

commons-logging-1.1.1.jar commons-logging-api-1.1.jar

Minha sugestão é usar o jcl-over-slf4j, pois assim você pode concentrar os logs em uma única API.

Creio que alguma outra lib esteja baixando o commons-logging como dependencia. O Lucas citou que pode ser o Spring. Tente colocar um ignore para a classe commons-logging e commons-logging-api na definição do Spring e também do tiles.

#34

Muito bom esse post!

Tentei testar aqui incluindo todos os jars do tiles, exceto aquele jcl-over-slf4j e o slfj4j-api, mas deu um erro de class not found: javax.portlet.PortletRequest

Então eu baixei o jar portlet-api_2.0.jar e então funcionou sem problemas. Alguém sabe o motivo disso?

#35

vc deve estar usando algo que depende da api de portlets

#36

Tipo o que? Comecei usando o projeto blank do VRaptor…

#37

eu que vou saber? :wink: talvez seja alguma lib que vc colocou no projeto, ou que está no servidor.

Ninguém usa portlets :stuck_out_tongue:

#38

Quem tá pedindo esse portlet é o próprio tiles:

O erro é:

org.apache.tiles.portlet.context.NotAPortletEnvironmentException: Cannot access portlet classes

#39

Ih, eu coloquei 2 jars do tiles que se chamam portlet rsrs

Excluí os jars: tiles-portlet-2.2.2 e tiles-portlet-wildcard-2.2.2 e aí funcionou.

Hehe, valeu!

Ah, tb excluí aquela classe portlet que eu tinha baixado. É nós.
