Chapter 13 Creating CORBA-Compatible Java Clients

Requirements

There are development and runtime requirements.

Development

To create Java clients, you need JDK 1.0.2 or 1.1 or a compatible Java compiler. You can use a visual development tool, such as PowerJ. PowerJ is a rapid application development (RAD) Java tool for creating Java applications, applets, and components. PowerJ offers additional features for Jaguar client development, such as the ability to generate stub classes from within the IDE, and predefined objects to simplify CORBA Orb calls.

Some server platforms may not have a JDK 1.0.2 implementation. In this case, you must develop JDK 1.0.2 applets and applications on a client machine that provides a JDK 1.0.2 development environment.

Unless you are using PowerJ, you must be able to run Jaguar Manager in order to generate Java stubs.

Runtime

Item	Description
Applets	To run Java applet clients, you need a browser that supports JDK 1.0.2 or above. Web browsers that support JDK 1.1 are preferred, such as Netscape 4.0. However, you may be constrained by your customer's installed browsers. You can use Marimba Castanet, available at www.marimba.com, to speed up the download of Java applet clients. Marimba Castanet 1.0 supports JDK 1.0.2 and Castanet 1.1 supports JDK 1.1.x.
Java Applications	To run Java applications, JDK 1.0.2 or JDK 1.1 must be installed on the client machine and the Java classes.zip must be included in the CLASSPATH environment variable.
