HotJava Views Administration

You can specify HotJava Views as the main application for JavaStation clients. This section briefly describes HotJava Views administration. See HotJava Views Administration online help for complete information.

HotJava Views offers the following integrated components:

• Selector - An environment manager with a push-button interface for switching between applications.

• MailView - An IMAP4 mail client for composing, sending, and saving messages and handling a variety of attachments.

• CalendarView - A calendar client for managing personal and group calendars

• NameView - An enterprise name directory service client that retrieves and displays a configurable set of fields and enables contact via email, URLs, and calendar data

• WebView - An HTML 3.2-capable web browser (URL access can be restricted by the system administrator)

HotJava Views Model

HotJava Views enables the zero client-administration network computer and also attempts to minimize server-side administration. Users are organized into groups in HotJava Views, and each group has its own profile, or set of properties.

Through HotJava Views Administration, you can define groups of users that share client properties, specify applications to appear in the Selector, specify any sliding panels that appear from the edges of the screen, administer other properties that affect the user's experience, and specify properties for particular network computers.

Selector refers to the vertical bar on the left side of the HotJava Views window where the applications buttons are located. It is easiest to think of Selector as being synonymous with HotJava Views itself. MailView, CalendarView and NameView are all applets that run within Selector, and their icons appear on the Selector bar.

When the JavaStation client boots, a URL is passed to Selector, which is a pointer to the initial configuration file. Once Selector locates the web server, it loads its set of properties files.

Properties

HotJava Views is controlled by a set of eight properties files. There are property files at the group, user, and client levels.

• Group properties - Each user is normally a member of a group and inherits the group properties. Group properties are usually the main source of the final properties. Users who are not members of a group inherit the group properties of the group currently designated as the "default"group. There are both initial and final group property files.

• User properties - Stored in the user's home directory. Initial group properties are overridden by the user's individual property file. Note that user properties cannot be administered by this Web-based interface.

• Client properties - Client properties are specific to a given network computer. They typically control a few items, such as the default printer, that are specific to the physical location of the JavaStation.

Administering Views

The HotJava Views administration is conducted from within a web browser. There is a link from the Netra J 2.0 software to this set of web pages. The link points to a web page that offers the choice of configuring the HotJava Views client applications or configuring the back-end services (for example, NameView database).

See "To Access HotJava Views Administration" for instructions on accessing the link to this administration tool.

To access the HotJavaViews Administration module, you should run Netra j on HotJava Browser 1.1. All other Netra j administrative modules are supported by any industry-standard browser.

Client-Side Administration

Upon selecting the HotJava Views client-side administration, a web page with an embedded applet is displayed. The applet contains the major tasks needed to configure HotJava Views client applications:

• Overview - Explanatory text that describes the overall flow of the administration applet. When first entering this applet, this button is highlighted and the overview text is displayed. This page will also have some pointers to task-based help (how to configure a selector, how to configure drawers, and other tasks).

• Application Palette - To add and configure the global properties of the applications that can be used in the selector and drawers.

• Groups & Configuration - Configuring what users are in what groups and defining the selector applications, sliding panels, and application properties specific to each group.

• Network Computer Props - Properties that are specific to a network computer hardware client, overriding properties set by the user or group. For example, you may have a public-use JavaStation that uses the printers nearest to it, rather than the printers assigned by the group or user.

At this time, HotJava Views does not support locales other than English. If you configure a JavaStation client to a locale other than English, HotJava Views will not display on the JavaStation.

Server-Side Administration

Configuring the server-side application services includes properties associated with the back-end server that the client applications connect to. These applications include Welcome, WebView, MailView, CalendarView and NameView.

To Access HotJava Views Administration

HotJava Views Administration can be run only from HotJava Browser supplied with Netra j 2.0. Make sure that HotJava Browser is installed before proceeding with this procedure. If you've installed HotJava Browser to the, you can run HotJava Browser by issuing the command /opt/SUNWnhjb/bin/hotjava.

1. From the Main Administration page, under "Network Services Administration" click Network Computer Server.

   The Network Computer Server Administration page is displayed.

2. Under "NC Webtop Applications Administration, " click HotJava Views Administration.

   The HotJava Views Administration window is displayed.

3. From the Main HotJava Views Administration page, click Edit Preferences Applet Security.

4. Set preferences to LOW for signed applets and MEDIUM for unsigned applets.

   • Signed applets contain a signature (a sequence of data embedded in the applet's code) and protects the applet against tampering. It is placed in the code by the originator of the applet.

   • Unsigned applets do not have protection against tampering.

5. Refer to the HotJava Views Administration online help for information on how to use HotJavaViews Administration.
