How to launch a file protocol URL with an anchor from Java?
From a Java program, I need to launch the default browser on a local HTML file, pointed to an anchor inside the file. In Java SE 6, the java.awt.Desktop.browse method will

For Windows only, you could try
System.exec("cmd.exe start file:///C:/foo/bar.html#anchor")讨论(0) -
I just solved this another way, because no amount of quoting or spaces in any of these examples worked for me.
1 Detect if the file URI has a anchor or query string
2 If so, create a temp file
File tmpfile = File.createTempFile("apphelp", ".html")with a meta-redirect to the actual file URI I desire:<html><head> <meta http-equiv="refresh" content="0;url=help.html#set_filter" /> </head></html>3 Execute the local rundll command using new temporary URI:
Runtime.getRuntime().exec( "rundll32 url.dll,FileProtocolHandler \"" +tmpfile.toURI().toString()+ "\"");I hope this works for you!

Solution on Windows is:
rundll32 URL.dll, FileProtocolHandler "file:///x:/temp/fragtest.htm#frag"
Mind the quotes!!!
rundll32 URL.dll, FileProtocolHandler file:///x:/temp/fragtest.htm#frag does work as expected.

You could try using BrowserLauncher2. It's a small and self-contained cross-platform library to open the default browser. It handles anchors perfectly.

I've done some investigation on this item here - note that opening
cmdand typingstart file:///c:/temp/test.html#anchoralso doesn't work.I think the only thing that actually works is to call a browser manually (or use a third-party tool that does this).
On Windows, you always have Internet Explorer, so you could call
Runtime.getRuntime().exec("cmd.exe start iexplore " + myURL)if you really don't want to find iexplore.exe yourself - but this doesn't always work either.讨论(0)
