XML : Java reference to folder not exist when deploy to GlassFish by Netbeans

I've a XSD file inside a directory called GML-XSD and using Netbeans 8.0.2 and inside the source code I use a String to this file

  String gmlXSDFile = "etc/GML_XSD/epsg/EPSG.xsd";    

The directory is project/GML-XSD/epsg/EPSG.xsd The problem is when I build the project and run it on Glassfish Server or Jetty, it complains about cannot find etc folder. How can I fix this to make sure it will try to find "etc/GML_XSD" inside the war file but not the directory where it is deployed.

Thanks.
