API Para Utilizar um Navegador Web na Aplicação

Boa Tarde pessoal,

Estou desenvolvendo uma aplicação que será necessário o uso de um web browser. Nos ambientes de programação da Microsoft sempre reparei que tem um componente WebBrowser.

No Java eu nunca ouvi falar, alguém sabe de uma biblioteca que posso utilizar para fazer essa função?

Obrigado

Eu achei esse código que simula um browser em java, porém nao é um browser ele usa esse JEditor pra mostrar a página html baixada com isso as funcionalidades básicas como cookies, javascript e outras não são aceitas…
