Rhapsody Developer Release Notes:
Java APIs for the Yellow Box

The Rhapsody Developer release contains an alpha version of the Java APIs for the Yellow box. Using these APIs, you can access virtually all the classes and protocols that make up Rhapsody's Application and Foundation frameworks. However, since this is an alpha version, be aware that these Java APIs are not yet complete and will no doubt change before the next release.

In particular, here are some limitations in the current release that will be removed in subsequent releases:

• Objective-C methods that return multiple values are not covered in the current Java API.
• Some functions in the Objective-C API are not yet available in the Java API.
• Some Objective-C categories have been wrapped in Java helper classes, but others are not yet available.
• Objective-C methods taking or returning class objects are not yet covered in the current Java API. Often a related instance method provides similar functionality.

For documentation on these Java APIs, see packages.html.

In addition to providing Java APIs for the Yellow Box, Apple has enhanced its development tools, including ProjectBuilder and InterfaceBuilder, to create and build Java applications.

In NextDeveloper/Examples/Java/AppKit/TextEditJava you will find an example application using the alpha Java APIs. TextEditJava is a simplified version of the TextEdit example written in Java.
