You can open a web browser from the IDE in two ways:
You can configure the IDE to use either the internal Swing HTML browser or an external web browser. Both types of browsers enable you to view external and local web pages, including online help and Javadoc documentation. An internal browser provides the highest level of integration with the IDE because you can embed an internal browser into another IDE window or an MDI frame.
The preferred browser for use with the IDE is an external browser, which provides more functionality than the internal browser and does not close when you shut down the IDE. You set your preferred browser in the Setup wizard, which you open from the Tools menu.
You can view the available web browsers and configure their
properties in the Options window. Expand IDE Configuration Server and External Tool Settings
Web Browsers.
