However, McNealy said twice he had never read Schwartz's blog, and that Sun's policy on blogs was that they were "not corporate but rather personal things."

They also disagreed on whether companies needed a license to use Sun's application programming interfaces for Java, a central issue in the case. McNealy said Sun licensed its APIs and compared them to "architectural drawings" -- similar to Oracle's characterization of the APIs as "blueprints."

Schwartz testified that companies could use Java without a license so long as they didn't claim to be "Java compatible" and use the Java logo.

Attorneys for each side tried to undermine the jury's confidence in both men's testimony. Robert Van Nest, an attorney for Google, suggested to McNealy that he was a "close personal friend" of Oracle CEO Larry Ellison and that he had made "a great deal of money" when Oracle bought Sun.

"I cashed out," McNealy said. "I think the money had already been made."
