Microsoft has appealed a November 17 preliminary court injunction forcing it to modify its Java products to comply with Sun?s Java specifications.
In its appeal, Big Green argues that the District Judge wrongly interpreted its license agreement with Sun.
Tom Burt, Microsoft associate general counsel, said: "Microsoft believes that the district court made several errors that should be reversed by the court of appeals."
But a Sun spokesperson refused to comment on any details of the appeal. "Our response will appear first in our reply brief, which will be filed in 28 days," she said.
Sun sued Microsoft for breach of contract on October 7, 1997, alleging that incompatibilities in Microsoft?s Java implementation violated the licensing agreement between the two companies.
On November 17, 1998, US District Judge Ronald Whyte issued a preliminary injunction, which forced Microsoft to support the Java Native Interface (JNI) in its Java Virtual Machine (JVM) and to make sure certain Microsoft-specific extensions to Java were turned off as the default in Microsoft?s Visual J++ development environment.
Microsoft has since released a version of its JVM, which it claims complies with the injunction.
"We are continuing to move ahead with our compliance effort while the appeals court considers our motion," said Burt.
The Sun spokesperson confirmed that the company was checking certain Microsoft?s products for compliance, but would not confirm whether or not it believes the new Microsoft JVM is conformant.
Elsewhere, the antitrust trial against the software giant is also advancing. By next Friday, both parties in the dispute must file their motions for summary judgement.
However, efforts remain under way to settle the dispute out of court. Two weeks ago, Judge Whyte ordered both parties to schedule a settlement meeting, and in a statement on Thursday, Sun repeated an earlier call to Microsoft to re-enter the Java fold.
"The ability to maximise compatibility and minimise switching costs is a central value of the Java platform - millions of developers and users rely on that value," it said. "They would be best served if Microsoft would come back into compliance with the Java specifications. We renew our invitation to Microsoft to do so, and renew our offer to assist them in coming into compliance," the statement added.
