HotJava Views Administration

Netra j automatically installs HotJava Views. If you are upgrading, you can lose groups you have configured, and application icons you have added to Selector, so copy the information elsewhere and replace it after the upgrade.

You can specify HotJava Views as the main application for NC clients. Netra j provides a link to the HotJava Views Administration tool that enables you to configure the HotJava Views application that deploys to NC 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 NC 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 NCs.

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 NC client boots, a URL is passed to Selector. The URL points to the initial configuration file. Once Selector locates the web server, it loads HotJava Views' 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 NC. They typically control a few items, such as the default printer, that are specific to the physical location of the NC.

Administering Views

The HotJava Views administration is conducted from within a web browser. There is a link from the Netra j 3.0 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 HotJava Views Administration module, use the HotJava Browser provided with the Netra j software. All other Netra j administrative modules are supported by any industry-standard browser. The path to the HJB is /opt/SUNWnhjb/bin/hotjava.

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 also has 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 an NC hardware client, overriding properties set by the user or group. For example, you can have a public-use NC that uses the printers nearest to it, rather than the printers assigned by the group or user.

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

1. From the Main Administration page, under "Network Computer Administration," click Network Computer Application Management.

   The Network Computer Application Management page is displayed.

2. Under "Netra Client Application Administration," click HotJava Views.

   The HotJava Views Administration window is displayed.

3. At the Main HotJava Views Administration page, on the HotJava Bowser menu 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) that 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. Click Apply.

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

Adding an Application Icon to the HotJava Views Selector

At installation, the application properties are set in the selector.apps file located in /opt/SUNWjdt/lib/props. There are several selector.desktop files corresponding to their group located under /opt/SUNWjdt/lib/props/group/selector.desktop. You should add the application entry to the appropriate group's selector.desktop file.

Upon installation of the application, the icon and all associated properties are added to the HotJava Views application palette automatically.

See the HotJava Views Administration online help for additional information.

You should specify the server parameters before configuring the client. For Citrix' WinFrame and GraphOn's GO-Joe, you specify the server through the Network Computer Application Management module.

To Add an Application Icon to the HotJava Views Selector

1. From the Main Administration page, under "Network Computer Administration," click Network Computer Application Management.

   The Network Computer Application Management page is displayed.

2. Click HotJava Views.

   The HotJava Views Administration page is displayed.

3. Select Client-side Configuration --> Groups and Configuration.

4. Select the Group to which you want to add the application icon and click the Selector Applications button.

5. Choose the application entry in the Application Palette and click Add.

   For example, GO-Joe and OC://WebConnect can be application entries.

6. Click OK.

7. Click Set Default Group to set this group as default.

   The default is Basic.HotJava Views Selector is now configured with the icon.
