[RESOLVIDO] Como configurar VRaptor + GuiceProvider

hugo.hlcxcx · Junho 22, 2012, 10:17pm

Pessoal, boa noite!

Não estou conseguindo utilizar o vraptor em conjunto com o Guice. Ja testei com PicoContainer e com o Spring e tudo funciona perfeitamente, porém com Guice é mostrado o seguinte erro:

Parece que não estão sendo encontradas duas classes do Guice e não sei como proceder nesse caso.

PS: Não fiz nenhuma configuração específica para o Guice no web.xml, apenas coloquei os jars na pasta WEB-INF/lib. Existe alguma outra configuração necessária para o funcionamento deste provider ?

Lucas_Cavalcanti · Junho 22, 2012, 11:10pm

o problema não é o guice… foi um erro do deploy da última versão do vraptor… pra corrigir, só colocar no web.xml:

<context-param>
    <param-name>br.com.caelum.vraptor.packages</param-name>
    <param-value>br.com.caelum.vraptor.http.iogi</param-value>
</context-param>

Lucas, ainda não funcionou. Quando eu adiciono o provider da JPA no web.xml, volta a ocorrer o erro relatado acima referente ao Guice.

Meu web.xml está assim:

		<param-value>br.com.caelum.vraptor.util.jpa</param-value>
	</context-param>
</web-app>

Existe algum conflito do Guice com o provider da JPA ?

Lucas_Cavalcanti · Junho 23, 2012, 12:03pm

vc não pode ter dois parametros com o mesmo nome… o packages aceita vários pacotes, separados por vírgula:

 <context-param>  
        <param-name>br.com.caelum.vraptor.packages</param-name>  
        <param-value>br.com.caelum.vraptor.http.iogi, br.com.caelum.vraptor.util.jpa</param-value>  
    </context-param>

Obrigado Lucas, agora sim funcionou.
