Classpath URI

[Christopher Benson-Manica]

How can I get a URI for an arbitrary file that is known to be
somewhere on the classpath? I don't want to specify either an
absolute or relative path to the file.

Use one of the "getResource" methods:
<http://java.sun.com/javase/6/docs/api/java/lang/Class.html#getResource(java.lang.String)>
<http://java.sun.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource(java.lang.String)>

There

are also matching getResourceAsStream methods that will open them for you.

One assumes that the OP wants URLs and not URNs. Were it only needed
to have a URN, the OP could prefix the FQN with an arbitrary scheme,
e.g., "fqn:com.lewscanon.foo.Foo". That would fulfill the OP's
request for a means to obtain a URI literally, if not usefully.
