Defining Application Settings with the App-Settings.xml Editor

Application settings (or App-settings) are the configurable settings for an application developed using the Junos Space SDK plug-in. These application settings are defined by an App-settings.xml file. When the application is deployed, the settings can be viewed and managed by the Junos Space UI. At a programmatic level, these settings can be retrieved and set by the /api/space/application-management/applications/{id}/settings-config APIs.

The Junos Space SDK plug-in provides an Eclipse-based App-settings.xml editor to edit the App-settings.xml file for your Junos Space SDK application. The App-settings.xml editor view opens in two tabs:

Note: It is not mandatory to have application settings defined for a Junos Space application.

Creating and Editing App-settings

  1. Select Junos Space > Create/Edit App-settings.xml from the Eclipse menu bar.

  2. The App-settings.xml Editor screen is displayed. If an App-settings.xml file does not already exist in the workspace, the editor opens a default App-settings.xml file in Create mode. Otherwise, the editor opens the existing App-settings.xml file for the workspace in Edit mode.

Note: The path of the App-settings.xml is <EAR-Project>/EarContent/META-INF/app-settings/App-settings.xml, where <EAR-Project> is the name of EAR Project. When you build and deploy your application, an XML Schema Definition file app-settings.xsd file is generated automatically.

Alternatively you can generate the app-settings.xsd file for your app-settings.xml without deploying the application by using the "Generate App-settings Schema" menu option. To generate <APP-NAME>-settings.xsd file for your app-setting.xml:

  1. Select File > Junos Space > Generate App-settings Schema.

Note: This option can be used if you have written your own script to deploy the Junos Space application.

Application Settings on Junos Space

While building an application, App-settings.xml is used to generate the <APP-NAME>-settings.xsd file, where <APP-NAME> is the name of the application. Once the application is deployed in Junos Space SDK, the contents of the App-settings.xml file are displayed using following steps:

  1. Browse to mainui, and navigate to Administration > Manage Applications.
  2. Select the application, and click Actions to open the slider.

  3. Click Modify Application Settings to view the settings configured in App-settings.xml.

Applying "Application Settings" using App-settings.xml Editor

In App-settings.xml, the root tag is "configuration". The following table lists the components, their descriptions, and their supported attributes. Only these types of components can be added in App-settings.xml.

label Mandatory Label displayed at specified location in slider

Note: The name or label of any component should start with an alphabetic character, and it can contain alphanumeric, space( ), or underscore(_) characters.

Using the App-settings.xml Editor
