The Teletext Generator requires a Sophora Server with a repository where special teletext nodetypes are configured.
The Teletext Generator can be customized using a Plugin API.
If a custom plugin is implemented, it has to be packaged as a Java Archive file (.jar) which will then be installed alongside the main application.
The application is distributed as an executable Spring Boot jar file.
- Unpack the
- Create /var/run/teletext-generator and /var/log/teletext-generator directories.
- Create a lib directory within the directory that contains the executable teletext-generator jar, and put the teletext plugin jar there.
To configure the application, an
application.yml file has to be placed in the same directory as the jar file. An example file is included in the packaging.
For the configuration of the Sophora Client we use the library Spring Boot Sophora Commons, further details about all available configuration properties can be found on the project page.
.conf file is recommended to manage the location of the applications PID-file and logs. The file must be named just like the jar but with the
.conf postfix instead of
.jar. For a complete reference of configuration options in the
.conf file, see the Spring Boot documentation.
Please make sure to create the configured folders for PID and logs as configured in the
.conf file. It is recommended to create a folder in /var/run/ (for PID) and /var/log/ (for logs), both named like the jar file (without postfix).
There is an example
.conf file included in the package.
Logging can be configured via
application.yml or by placing a
logback.xml in the config directory. Please refer to the Spring Boot documentation for further reference.
By default, a customer-specific teletext plugin must be placed into the lib directory within the directory that contains the executable Teletext Generator jar. The directory can be customized in the
The base Java package of the plugin needs to be specified in the
pluginPackages property in
If the plugin is depending on libraries which are not shipped with the core Teletext Generator application, the jar files of these libraries may be put into the lib directory as well. As these jar files end up in the core classpath of the Teletext Generator, refrain from adding differing versions of libraries already provided by the Teletext Generator.
You can verify that a plugin was loaded in the log output during the startup of the Teletext Generator ("
Picked up plugin-provider bean of type 'PluginClassName'.").
Since the jar is executable (contains an embedded launch script), it may simply be launched like this:
$ ./teletext-generator.jar start
Also, the application may be registered as an
init.d or systemd service. See the Spring Boot documentation for further details on this.
The running Teletext Exporter provides different HTTP endpoints at the port configured in the
application.yml file. For instance, the preview for teletext documents could be at
