Using the Java Bridge

In the world of Mac OS X and WebObjects programming, there are two languages in common use: Java and Objective-C. This document describes the Java bridge, a technology from Apple that makes communication between these two languages possible.

The first section, [Introduction](JavaBridge.1.html#BGCDBCJG)
gives a brief overview of the bridge's capabilities.

For a technical overview of the bridge, see [How the Bridge Works](JavaBridge.2.html#BGCDJHJJ)
.

To learn how to expose your Objective-C code to Java, see [Wrapping Objective-C Frameworks](JavaBridge.5.html#BGCBEFED)
.

If you want to write Java code that references Objective-C classes, see [Using Java-Wrapped Objective-C Classes](JavaBridge.4.html#BGCECHGC)
. If you are writing Objective-C code that references Java classes, read [Using Java from Objective-C](JavaBridge.3.html#BGCBFDJI).
