The dispute is over Sun's Java Virtual Machine (JVM), a piece of
software that is needed for a computer to run software written in
Java. The language, developed by Sun in 1995, is popular for
internet-based applications.
However, its future was threatened by Microsoft's decision to
drop Sun's JVM from its flagship operating system, Windows XP,
because Microsoft has its own competing language and virtual
machine.
Seeking damages, Sun accuses Microsoft of using its dominant
position in the market for operating systems to sidetrack Java, in
breach of antitrust laws. Sun also alleges that Microsoft views
Java as a threat in the new markets for mobile phones and handheld
devices.
In a hearing that started on Tuesday and it is expected to
conclude today, Sun has asked US District Judge J. Frederick Motz
to issue an order requiring Microsoft to distribute its JVM with
Windows until the case is resolved.
