Installing HATS LE

For installation instructions, please refer to Installing HATS LE. Note these additions to the installation instructions:

Configuring HATS LE

Saving your template using the Save as button

The Save as option when saving your template using the Template Editor does not warn you that saving the file using the same file name will replace the existing file. It should be noted that if you use this option and do not rename the file, your file will be overwritten with your changes.

Template settings refreshed after reconnecting to your session

In HATS LE Getting Started, is states that if you make changes to the template or transformations settings, you will see the changes when your browser is refreshed.

In order to see changes to your template or transformation settings, you need to disconnect from your session and then reconnect for the changes to take effect.

Help panel for Function Key Settings does not match the page

When you click on the Help button on the Function Key Settings page, you will notice an additional rendering setting called Layout with formatting options Number of columns per row  and Separator.  These three settings are not available in HATS LE.

Configuring SSL for your HATS LE application

In order you completely configure your HATS LE application for SSL, you must change the class loader policy of the HATS5LE.ear to Application using the following steps:

  1. Open the WebSphere Administrative Console.
  2. Click on the HATS5LE.ear in the list of Enterprise Applications.
  3. Modify the option WAR Classloader Policy to Application.
  4. Click Save.

Once the SSL file is imported and configuration settings are finished, the HATS LE application must be restarted before your SSL connection can take effect.

Extra named style (CSS Class) to enable style sheet color mapping of reverse video fields

HATS LE V5 enables reverse video to be rendered on a Web page as displayed on host screens. HATS formerly only supported an inline style for reverse video fields which allowed displaying a common background (gray by default) for text in these fields.

To enable reverse video support in HATS, you must change some of the settings of the field widget by going to the Transformation Settings page and clicking the Settings button for the Detect fields option.  This will open the Field settings page where you must do the following:

  1. Select Enable extended attributes
  2. Remove the setting (background-color:#666666) from the Reverse video style field. This removes the former gray background color that would override the named style (CSS class) mapping provided by this feature.

For example, suppose a host screen has a field with a black background, and red text. When the reverse video attribute is turned on for this field, the host terminal displays black text with a red background. Previous versions of HATS could not render this combination in its HTML display of the host screen.

To enable reverse video, HATS generates an additional named style (CSS class) that you can use. Here are examples of text rendered by HATS:

Before enabling reverse video:

<input name="in_1989_9" maxLength="9" class="HLRED" onChange="" type="text" onClick="" onFocus="" value=" CURRENT" size="9">

After enabling reverse video:

<input name="in_1989_9" maxLength="9" class="HLRED RHLRED" onChange="" type="text" onClick="" onFocus="" value=" CURRENT" size="9">

Notice the addition of the second named style (CSS Class), RHLRED. When reverse video is enabled, an additional named style is appended to the text rendered by HATS LE, for fields of any color. The new named style will start with an R followed by the current color mapping (RHBLUE, RHWHITE, and so on).

The named style will contain the new style tags that give the desired display. Following are example style tags that could be used for the new named styles associated with reverse video.

.RHBLANK {
        color: black;
	background-color: #00ff00;
}

.RHBLUE {
        color: black;
	background-color: #3c9dff;
}

.RHGREEN {
        color: black;
	background-color: #00ff00;
}

        color: black;

}

	background-color: #40c040;
}

        color: black;

}

        color: black;
	background-color: #ff4040;
}

        color: black;
	background-color: #c040ff;
}

.RHLYELLOW {
        color: black;
	background-color: #c0c000;
}

.RHHWHITE {

}

These reverse video style tags match some of the color styles defined in the blacktheme.css style sheet. The styles can be added to your project by:
