Visão Geral

Curso Implementing a Service-Oriented Architecture with XML Web Services in Java, Este workshop avançado e aprofundado explicará a necessidade de uma arquitetura orientada a serviços (SOA), melhores práticas para integração entre sistemas corporativos usando SOA e fornecerá detalhes concretos sobre a implementação e orquestração de serviços da Web com a API Java para XML Web Services (JAX-WS) e a API Java para XML RESTful Services (JAX-RS). Este curso também fornece uma introdução abrangente ao XML e como analisar, criar, transformar e vincular ao XML a partir de programas Java.

Objetivo

Após realizar este Curso Implementing a Service-Oriented Architecture with XML Web Services in Java, você será capaz de:

1. Projetar uma arquitetura orientada a serviços com XML Web Services
   
2. Descrever a estrutura de um documento XML usando esquema
3. Interaja com documentos XML de programas Java usando SAX, DOM, JAXB e TRaX
4. Crie serviços e clientes da Web em nível de XML usando as APIs Provider e Dispatch
5. Crie serviços da Web RESTful usando JAX-RS
6. Crie clientes para serviços RESTful usando a API Jersey Client
7. Monitorar mensagens SOAP entre serviços da Web e clientes
8. Gravar e implantar WSDL para serviços da Web que priorizam o WSDL
9. Criar serviços da Web que priorizam o WSDL e o primeiro código
10. Criar clientes de serviço da Web síncronos e assíncronos
11. Interponha manipuladores SOAP personalizados no lado do cliente e no lado do servidor
12. Orquestrar serviços da Web
13. Habilite a otimização, confiabilidade e segurança de mensagens
