PropertiesChecker

This plugin demonstrates how to write a plugin that implements PropertiesChecker interface. Further details can be found in the server programming guide.

Activate the included plugin

In order to test this plugin, you need to copy the plugin ZIP file propertieschecker.zip into the plugins folder of your installation or upload the plugin using Drag & Drop in the Store application. Afterwards the server needs to be restarted. You can check if the plugin was loaded in the dialog Store application. If there are problems, then check the log file of the server for more details.

Server Plugin

As a next step you can start to write your own custom server plugin. It has to implement the interface com.inet.plugin.ServerPlugin and must have an empty public constructor. Your custom implementation of the PropertiesChecker has to be registered in the method registerExtension to be recognized by the server.

This can look like:

public void registerExtension( ServerPluginManager spm ) {
    spm.register( PropertiesChecker.class, new CustomPropertiesChecker() );
}

Please refer to the sample com.inet.samples.propertieschecker.CustomPropertiesChecker for a full code sample.

Build the plugin

The following steps need to be taken if changes are made to the plugin code.

The plugin.properties and server plugin class are preconfigured to be used without modifications. If the sample is the basis for a custom plugin or just needs some adaptions, please refer to the platform programming guide for detailed instructions.

Classpath

In order to build this plugin the following jar files are required at the least:

  • inetcore.jar (included in the core directory)
  • reporting.jar (included in the plugins/reporting.zip file)

These files are part of the SDK but will also be loaded from our public maven server when using the packaged build.gradle.

Compiling

The plugin must be compiled into a jar file that is named like the id of the plugin. In this example it is propertieschecker.jar. It also must contain the compiled sources as well as required language resources and images.

The target plugin is a zip file, named propertieschecker.zip in this example. It contains the compiled jar file and the plugin.properties which configures the custom plugin.

The provided build.gradle in the sample can be used to build the plugin. Different build systems can be used as well but have to be configured manually.

Deploying

Copy the ZIP file of the plugin into the plugins directory of the server or Drag & Drop the plugin into the Store application of the server for sideloading. Then restart the server. If there are problems, then check the log file of the server for more details. The "Config" logger is used to log plugin registration issues.
