I think part of the confusion comes from Mark Reinhold's original blog announcing Jigsaw (http://blogs.sun.com/mr/entry/jigsaw): "This module system will be available for developers to use in their own code, and will be fully supported by Sun, but it will not be an official part of the Java SE 7 Platform Specification and might not be supported by other SE 7 implementations." So in that respect, Jigsaw does compete with OSGI, since developers can use it to modularize their software. And with Sun supporting it, you could make up the typical "Sun re-invents the wheel, forces it on Java and then makes money from it" story. However, Mark also said: "If and when a future version of the Java SE Platform includes a specific module system then Sun will provide a means to migrate Jigsaw modules up to that standard. In the meantime we’ll actively seek ways in which to interoperate with other module systems, and in particular with OSGi." So at least on paper, the Jigsaw / OSGI worlds aren't that far apart. We'll see what IBM does with Jigsaw once they acquired Sun... ;-) Sorry, couldn't resist! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
