Answer 1

I am a bit rusty with JCR and I have never used 2.0 but this should get you started.

See this link. You'll want to open up the second comment.

You just store the file in a node and add additional metadata to the node. Here is how to store the file:

Node folder = session.getRootNode().getNode("path/to/file/uploads"); 
Node file = folder.addNode(fileName, "nt:file"); 
Node fileContent = file.addNode("jcr:content"); 
fileContent.setProperty("jcr:data", fileStream);
// Add other metadata
session.save();

How you store meta-data is up to you. A simple way is to just store key value pairs:

fileContent.setProperty(key, value, PropertyType.STRING);

To read the data you just call getProperty().

fileStream = fileContent.getProperty("jcr:data");
value = fileContent.getProperty(key);
