Excessão na inicialização do jboss com seam.

  Pessoal,   Quando tento iniciar o jboss com um projeto com seam está ocorrendo a seguinte excessão. Provavelmente é a versão da lib do dom4j. Já tentei de tudo mas não consigo sair do lugar. Se alguem souber algo, por favor, help me     java.lang.LinkageError: loader constraint violation: when resolving method "org.dom4j.io.SAXReader.setEntityResolver(Lorg/xml/sax/EntityResolver;)V" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the current class, org/jboss/seam/util/XML, and the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) for resolved class, org/dom4j/io/SAXReader, have different Class objects for the type org/xml/sax/EntityResolver used in the signature at
