You probably should follow the detailled instructions in Sun's Java Tutorial, here:
http://java.sun.com/docs/books/tutorial/
Click on First Steps and then follow the instructions EXACTLY, including clicking the link to the Installation Instructions and reading that entire document. Verify that what you installed matches what the Installation Instructions show.
Follow the instructions without skipping anything, and without deviation.
