Visão Geral

O Curso JEE - Develop Web Services with JAX-WS & JAX-RS cobre o design e a criação de clientes e serviços da Web SOAP e RESTful. Você usará o Ambiente de Desenvolvimento Integrado (IDE) NetBeans para desenvolver serviços da web JAX-WS e JAX-RS e implantar esses serviços no Oracle WebLogic Server. A maioria dos tópicos abordados são portáteis em todos os servidores de aplicativos que suportam os padrões de serviço web JEE.

Objetivo

Após concluir este Curso JEE - Develop Web Services with JAX-WS & JAX-RS, você será capaz de:

• Aplicar a API JAX-WS na criação de Web Services e clientes SOAP
• Aplicar a API JAX-RS na criação de Web Services RESTful
• Serviços Web seguros usando WS-Security, Jersey e OAuth
• Lidar com erros e exceções em serviços Web e clientes
• Crie documentos XML usando declarações de namespace e esquema XML
• Produza e consuma conteúdo XML e JSON usando JAXB
• Crie clientes RESTful Web Service usando a API Jersey Client
