Get relative path to a folder inside OSGI Bundle

Question

I've developed a sample OSGI bundle and deployed it into Karaf, and the bundle contains a folder on the same level as the source.

My class needs to load data from this folder, but I got an error each time:

java.lang.IllegalArgumentException: No such group file: ./data/...

My question is: how do I use a relative path to a folder inside an OSGI Bundle?

Answer 1

solved using context from bundle:

URL wfl = context.getBundle().getResource("data1/file.txt");

or

URL url = MyClass.class.getClassLoader().getResource("data1/file.txt");
            if (url != null) {          
                mFile = FileLocator.toFileURL(url).getFile();

Hope this help someone
