You can't - you have to use the OAuth authentication flow, you cannot authenticate using a username and password.

Does this mean, every user who want to access dropbox files, need to create an dropbox app and generate consumer key and secret?

No, users just have to authenticate using the OAuth process flow - the application will have your keys and secrets embedded in it, they don't have to generate their own.

As I said before, you can't have your users present their Dropbox username and password to your application - that is not allowed.

You have to use the authentication flow detailed here:

https://www.dropbox.com/developers/core/start/java

This flow connects to the Dropbox servers using a browser instance, allows the user to authenticate directly with the Dropbox servers, and gives you an authentication token at the end of it. It is that authentication token that you then use to access Dropbox on behalf of that user.
