That's a very broad question. Answers range from take a holiday to update your resume to see a career counselor. You have to decide what you're after, and if you want advice on it, you might tell us more of what that is. If you mean in terms of a next certification, check out the jCert intiative.
Perhaps you can try becoming a Sun Certified Java Developer. I hear it's quite well-respected. If you want to work with J2EE, becoming a Sun Certified Web Component Developer may be a good choice. You could also try to use the SCJP to get yourself a (new) job. It all depends on the situation you are in and your desires.
I have not found my SCJP to be of any help in my job search so the next step after getting it is important. Of course I have no practical Java experience. I would not recommend the Developer certification without substantial experience in Java. If you are currently working, ask your employer what certification he recommends. Otherwise concentrate on getting experience.
