Using Google voice and video chat plugin to record voice

I'm trying to develop an application that records audio from the browser. Can I use the Google vioce and video chat plugin 开发者_运维知识库that Gmail internally uses to record audio? If yes, How can I do this? If no, is there any other way I can record audio using J2EE?

Thanks.
