Opening a browser window via OpenAPI

I'm looking for a code snippet for opening up a browser window from within a plugin, similar to what's done by the "Generate Javadoc" or "Export to HTML" Actions. My use case is similar to those, as I'm using the PSI to generate static analysis/metrics/cross-reference reports as directories of HTML pages, and wish to pop up a browser with a top-level index file when done. Clearly this is doable via hacking with system properties and Runtime.exec, but if there is a 'blessed' way of doing so I'd love to see it.

Thanks.
