Problemas para subir aplicação.

[Pedro Henrique Oliveira]

Boa noite, galera!
Estou começando um projetinho com um amigo meu e criamos juntos o projeto, seguindo os passos da page de dependências do site do VRaptor.

Na minha máquina tudo funciona de maneira perfeita. Eu buildo a aplicação via maven e executo-a no tomcat 7 sem problema algum.
A complicação é quando tentamos executar o mesmo código na máquina do meu amigo. Ao tentar rodar o tomcat temos o seguinte erro:

GRAVE: Exception sending context initialized event to listener instance of class org.jboss.weld.environment.servlet.Listener
java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, org/jboss/weld/environment/servlet/Listener, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type licationContext.addELResolver(Ljavax/el/ELResolver;)V used in the signature

Será que algum de vocês já passou por esse problema?

Obrigado, galera!

Galera, consegui resolver..

Para os que tiverem o mesmo problema, tive que adicionar o trecho abaixo nas dependencias do weld:

<exclusions>
    <exclusion>
           <groupId>org.jboss.spec.javax.el</groupId>  
        <artifactId>jboss-el-api_3.0_spec</artifactId>
    </exclusion>
</exclusions>
