O que tem nessa linha?
Tem certeza de que não está chamando o getTextContent() em um elemento inválido?

bom dia, ele esta dando erro no getTextContent() já fiz varias pesquisas e nao consegui a devida solucão

dá este erro java.lang.AbstractMethodError: Receiver class org.apache.xerces.dom.DeferredElementImpl does not define or inherit an implementation of the resolved method ‘abstract java.lang.String getTextContent()’ of interface org.w3c.dom.Node.

Sim, você já postou o StackTrace acima.

O que tem nesse código View.LerXmlView.lerXML(LerXmlView.java:191) ?
Teria como postar também o XML que está lendo?

Seu XML está mal formado, assim como o @staroski já disse.

1 curtida

Quando postar código, utiliza o botão de texto pré-formatado do fórum, senão fica ruim de ler.

Seu XML continua mal formado

Antes das seguintes tags tem um monte de texto solto no arquivo:

  • codigo_autenticidade
  • nome_razao_social
  • ponto_referencia
  • aliquota_item_lista_servico
  • codigo_local_prestacao_servico
  • ddd_fone_comercial
  • codigo_local_prestacao_servico

Você não tem nenhum XSD para verificar se seu XML está sendo gerado corretamente?

58100-NFSE-049.xml (2,1,KB)

Esse XML parece OK.

Provavelmente o erro está no seu código Java, deve estar tentando recuperar texto de uma TAG que não comporta texto.

O que tem nessa linha View.LerXmlView.lerXML(LerXmlView.java:191) ?

obrigado por tentar me ajudar, vou continuar pesquisando aqui até achar. vlw

Talvez se partilhares o teu código alguem te consiga ajudar. Assim, só com o stacktrace é praticamente impossivel.
