    CHAPTER

    1 Publishing with WebLogic ZAC

    This section provides an overview of using the WebLogic Zero Administration Client (ZAC), including the following topics:

    n Introduction

    n Trying Out the ZAC Demos

    n How ZAC Works

    n Setting up WebLogic for Publishing with ZAC

    Introduction

    Note: The WebLogic Zero Administration Client is a deprecated product. BEA recommends that you use the Sun Microsystems Java Web Start product. Java Web Start is a Java 2-compliant product that enables users to download Java applications.

    WebLogic ZAC, the Zero Administration Client utility, lets you publish and republish applications, applets, and libraries with ZAC, so that they are transparently and automatically updated to the latest version on the end user client machine. With ZAC, you no longer need to manually distribute applications, applets, or libraries to your clients; you can depend on ZAC’s automatic services to do so.

    Using the Zero Administration Client 1-6

    ZAC is extremely efficient. When a ZAC application is republished, only the minimal amount of data is sent over the network to each client, to bring the applications on your clients up-to-date. In a typical scenario where little or nothing has changed, the overhead for checking for new files at startup is not noticeable to a user.

    ZAC is highly configurable, so that you can design how your application should be published, installed, and updated. You can check for updates to the application and to its dependent libraries each time the application starts or stops; on a scheduled basis, or you can disable the check for new ZAC updates altogether. Although this would disable ZAC’s most powerful feature, it may be desirable for packages that you intend to distribute once only as a static version.

    ZAC uses a protocol called the HTTP Distribution and Replication Protocol (DRP), a specification submitted to the W3C in August 1997 for the efficient replication of data over HTTP.

    This document includes instructions on how to use the ZAC Publish Wizard to publish applications on a WebLogic Server for distribution to your users.

    Trying Out the ZAC Demos

    When you install on Windows with the install shield (.exe) version, WebLogic comes out-of-the-box with two ZAC packages, ZSimple and ZUpdate, that you can try out immediately to see how WebLogic ZAC works. (This pre-installed demo does not function correctly if you have installed WebLogic Server from the .zip file distribution.)

    1. Start WebLogic. (You will need to know the system password to publish.)

    2. Start the ZAC Publish Wizard. Win32 users can use the shortcut for ZAC Publisher available in the WebLogic directory in the Start menu.

    Non-Windows users can start the Publish Wizard from the command line (after setting your CLASSPATH with this command:

    $ java weblogic.PublishWizard
