Developing iPhone Applications using Java

ABSTRACT

Apple's iPhone has resulted in significant interest from users and developers alike. Apple's SDK for the iPhone is based on Objective-C as the development language as well as Cocoa for the GUI.

Unfortunately Apple's license agreement for the iPhone SDK prohibits the porting of the Java virtual machine to the iPhone. In this presentation we introduce an Open Source Java-to-Objective-C cross-compiler as well as a Java-based implementation of the Cocoa library. With the help of these tools, iPhone applications can be written in pure Java. Using the Java version of Cocoa, it is possible to run a Java-based iPhone application as a Java desktop/applet application that can be cross-compiled to run natively on the iPhone. The talk will discuss the challenges of the Java-to-Objective-C cross-compiler as well as the Java-based version of Cocoa. Details are available at

Cool, great summary of the JVM, nice 'hack' in the best sense of the word. The only sad part is that java on the iphone would make this complexity irrlevant. Recoding Cocoa in Java seems to be the biggest unforunate part of this project.

C-Objective code looks terrible.

Also, he says Apple is planning on adding garbage collection to Objective-C, but in fact Objective-C 2.0 *already* has garbage collection. It's just not available on the iPhone (probably for performance/memory reasons)
