Definition of Merapi originally a volcano in Central Java, but there's a new term about Merapi :
"Merapi is a bridge between applications written in Java and those running in and created for Adobe AIR™ (Adobe Integrated Runtime™)."
Merapi has huge potential and we can looking forward discovering possibility when we can combine the power of Java with the richness and ubiquity of Adobe AIR.
Another project is Artemis active on Apollo (Adobe AIR beta) era but it was abandoned. Today the project rebirth under the name of Merapi.
Merapi use Java to connect AIR to the desktop. The project will be (unfortunately not yet) distributed as a freeware and then as an open source project on Google Code.
Using Merapi, Adobe AIR™ applications can "talk" to other software that the user has installed on their computer. In addition, Merapi allows AIR™ applications to serve as a user interface to just about anything that a Java™ application can do on a user's computer.
