Bob Muglia, Microsoft's senior vice president of applications and tools, has denied allegations that the software giant tried to "undermine" Sun's Java programming language and scare Real Networks out of the Windows multimedia market.
Muglia was called as a defence witness by Microsoft to counter the accusations of James Gosling, a Sun vice president and the creator of Java.
Gosling, who testified in December as a Government witness, accused Microsoft of deliberately distributing an incompatible version of Java in order to undermine the language's cross platform capability.
But Muglia, in his written testimony released on Thursday, claimed that Microsoft's implementation of Java was in fact more compatible than any other, including that of Netscape, Apple and even Sun itself.
"Sun's own versions of its Java technology have changed over time so that Java programs written on early versions of Java will sometimes not run on newer versions, and vice versa," Muglia wrote.
He also argued that developers have always been able to choose between writing platform independent, "least common denominator" Java or using Microsoft's platform specific extensions.
However, Muglia did admit that Microsoft's Java strategy was aimed at defeating Sun's ambitions to establish it as a competitor to Windows.
"If we were right and successfully executed our strategy, then Sun's attempt to use Java to establish a new development platform to replace Windows would not be successful," he wrote.
Microsoft's licensing dispute with Sun over Java is the subject of a separate lawsuit to the US Goverment?s antitrust trial, and is still ongoing lawsuit following its filing by Sun in October 1997. A preliminary injunction forced Microsoft to modify its Java virtual machine and some of its other Java products, but Big Green has appealed against the decision.
In a supplemental document, Muglia also denied allegations by Bruce Jacobsen, president of Real Networks, which claimed he threatened Real Networks against competing with Microsoft in the multimedia market during a meeting in July 1997.
