Ok, this only works on Equinox. This is no cross-OSGi implementation way to get the absolute path of a bundle. Having said that, here is the code for Equinox (apologies for the formatting, this forum eats my indentation, paste it into your editor and format it):

URL entry = context.getBundle().getEntry(".");
if (entry != null)
{
URLConnection connection = entry.openConnection();
if (connection instanceof BundleURLConnection)
{
URL fileURL = ((BundleURLConnection) connection).getFileURL();
URI uri = new URI(fileURL.toString());
String path = new File(uri).getAbsolutePath();
System.out.printf("This is the path: %s\n", path);
}
}

Note that BundleURLConnection is an internal Equinox class and you will get a warning marker in Eclipse as a result of using it.

Enjoy.

Many thanks, Brett! I tried your code but this first line gives me null

URL entry = context.getBundle().getEntry(".");

David, I'm not sure why that doesn't work for you, but you can use any file that resides in the root of your bundle.

Many thanks to Alex & Brett for help with this.

Brett, your method of getting absolute path work if I specify an actual file as in
URL entry = context.getBundle().getEntry("README.txt");

Alex has good points. I will endeavor to redo my app in the proper way.

Thanks!!

Hi,

How about this (unless you found a way without absolute paths ;-):

URL entry = context.getBundle().getEntry("/");
String path = FileLocator.toFileURL(entry).getPath();

FileLocator (from org.eclipse.equinox.common) isn't even internal.
Except: on windows we observed the above code to produce paths looking like:
/C:/Programme/Eclipse/plugins/my.plugin
a workaround for that is
String fixedPath = new File(path).getPath();
=:-0

On Equinox 3.4 it's org.eclipse.core.runtime.FileLocator

Thanks for the tip !

Still no generic OSGi way to find the bundle's root file path ?
