Problema com o servidor

Olá pessoal! Obrigado por vir até aqui me ajudar.

O meu servidor está subindo corretamente e exibindo o XML, porém no console ele aparece uma série de erros ao iniciar.

O que poderia ser esse problema?

Isto aí acontece porque estão faltando alguns arquivos de dependência ao projeto, adicione os seguintes JAR's ao seu Build Path:

  1. jaxb-impl-2.3.2.jar
  2. jaxb-core-2.3.0.1.jar
  3. javax.activation-api-1.2.0.jar
  4. jaxb-api-2.3.1.jar
