All you can really do is retrieve the InputStream for said file. Which
should be enough, and the nodes hold the rest of the info if you need it
obviously (file name, type, etc).

Something like:

Node resNode = fileNode.getNode("jcr:content");
resNode.getProperty("jcr:data").getStream();

Where fileNode is the jcr:file node type. You wont be able to actually get a
File object becuase thats part of JCR, that it extracts that stuff away from
you, and you just deal with the contents and info.
