Sometimes, nobody is grateful. That's how it must seem to Sun Microsystems, at times, with its invention of Java. Almost from the day the company brought Java to the works, Sun has been hit by two conflicting questions: "How are you going to insure Java remains an open standard?" and "How are you going to make money from the technology you invented?" With Java, Sun is balancing the virtue of an open standard with the financial benefits of owning a proprietary technology.
