Why do Properties load method failed in Eclipse plugin dev?

I'm trying to use Properties's load() method in my Eclipse plugin project. Since I wanna put the propertie file in a folder like this:

Pluging Project/
               |
               +----/src/...   
               +----/config/config.properties
               +----/icons/...
               +----META-IN/
               +----build.properties
               +----plugin.xml

And then I try code like this but failed:

Properties prop = new Properties();
InputStream inputStream = (InputStream) Activator.getDefault().getBundle().getEntry("/config/config.properties").getContent();
prop.load(inputStream);

This method receipt a input byte stream as parameter. And I'm pretty sure Activator.getDefault().getBundle().getEntry() returns a InputStream. And if I put the propertie file in the same location of the calling class and use

InputStream inputStream = this.getClass().getResourceAsStream("config.properties");

It will go well.

So any hints?

The URL returned by Bundle.getEntry uses an internal Eclipse scheme and doesn't always support getContents(). You need to call org.eclipse.core.runtime.FileLocator.toFileURL() to convert it:

URL url = Activator.getDefault().getBundle().getEntry("/config/config.properties");

url = FileLocator.toFileURL(url);

InputStream inputStream = (InputStream)url.getContent();

Also make sure you have the config directory listed in the build.properties
