用默认浏览器打开网页很简单:

Opening a web page with the default web browser is easy:

java.awt.Desktop.getDesktop().browse(theURI);

嵌入浏览器并不容易.JEditorPane 有 一些 HTML 能力(如果我没记错我有限的 Swing 知识的话)，但它非常有限，不适合通用浏览器.

Embedding a browser is not so easy. JEditorPane has some HTML ability (if I remember my limited Swing-knowledge correctly), but it's very limited and not suiteable for a general-purpose browser.
