Did you notice that the error message states very precisely the reason for the error, and even provides a link to a more in-depth discussion of the problem?

[Ulf Dittmer]

How are you specifying username and password? Make sure you proceed according to http://www.oracle.com/technetwork/java/faq-135477.html#gmail

Once you are doing all of that, and it still doesn't work, post the code you have.
