I was looking for the Java Naming and Directory Interface (JNDI) service provider for the file system. As far as I know, Oracle ships bundled with the JDK only service provider
You can possibly dowload it from Maven Central
<dependency>
<groupId>com.sun.jndi</groupId>
<artifactId>fscontext</artifactId>
<version>1.2-beta-3</version>
</dependency>
Searching for alternative leads to SwiftMQ implementation
I was able to download this library from oracle's archive downloads. This page contains long list of downloads. Try [Ctrl+F] for "File System Service Provider, 1.2 Beta 3". The jar file is 14 years old :) It was released on Mar 29, 2000.
Not found in maven central and mvnrepository.com and jfrog. Currently (2015) found at oracle archive to download manually and for maven a similar dependency here is the pom.xml:
<dependency>
<groupId>com.sun.messaging.mq</groupId>
<artifactId>fscontext</artifactId>
<version>4.6-b01</version>
</dependency>
