Fortunately, the process was described by Josh here. So I've taken it and implemented it in Java, and it seems to work. It's a very basic example that authenticates with dropbox then uploads a file called "testing.txt" containing "hello world."
Of course, more functionality is available than this, but this is the hard part (at least I found working this bit out the hard part.) Once you've got your DropboxAPI object, you can work most things from there using the supplied Javadoc.

public class DropboxTest {
private static final String APP_KEY = "APP KEY";
private static final String APP_SECRET = "SECRET KEY";
private static final AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
private static DropboxAPI<WebAuthSession> mDBApi;
public static void main(String[] args) throws Exception {
AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE);
WebAuthInfo authInfo = session.getAuthInfo();
RequestTokenPair pair = authInfo.requestTokenPair;
String url = authInfo.url;
Desktop.getDesktop().browse(new URL(url).toURI());
JOptionPane.showMessageDialog(null, "Press ok to continue once you have authenticated.");
session.retrieveWebAccessToken(pair);
AccessTokenPair tokens = session.getAccessTokenPair();
System.out.println("Use this token pair in future so you don't have to re-authenticate each time:");
System.out.println("Key token: " + tokens.key);
System.out.println("Secret token: " + tokens.secret);
mDBApi = new DropboxAPI<WebAuthSession>(session);
System.out.println();
System.out.print("Uploading file...");
String fileContents = "Hello World!";
ByteArrayInputStream inputStream = new ByteArrayInputStream(fileContents.getBytes());
Entry newEntry = mDBApi.putFile("/testing.txt", inputStream, fileContents.length(), null, null);
System.out.println("Done. \nRevision of file: " + newEntry.rev);
}
}
To use the token pair in future, instead of doing:
WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE);
You would do:
WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE, new AccessTokenPair(key, secret));
...where key and secret are the ones printed in the example above. You can then skip the rest of the auth code (up until you create the DropboxAPI object.)
