Lightweight Modular Service Container - Based JBoss Modules and Maven. It's easier than OSGi :)
First, include the Furnace dependency in your project:
<dependency>
<groupId>org.jboss.forge.furnace</groupId>
<artifactId>furnace-se</artifactId>
<version>${version.furnace}</version>
</dependency>
Then configure the container and start it:
Furnace furnace = FurnaceFactory.getFurnace()
furnace.addRepository(AddonRepositoryMode.MUTABLE, new File(OperatingSystemUtils.getUserForgeDir(), "addons"));
To install addons, you will need to add the following dependencies to your project:
<dependency>
<groupId>org.jboss.forge.furnace</groupId>
<artifactId>furnace-manager</artifactId>
<version>${version.furnace}</version>
</dependency>
<dependency>
<groupId>org.jboss.forge.furnace</groupId>
<artifactId>furnace-manager-resolver-maven</artifactId>
<version>${version.furnace}</version>
</dependency>
Then create a new AddonManager:
AddonManager manager = new AddonManagerImpl(furnace, new MavenAddonDependencyResolver())
Once you have an AddonManager instance, you can begin to install addons (You can do this while Furnace is running):
InstallRequest request = manager.install(AddonId.from("org.example:my-addon", "1.0.0.Final"));
request.perform();
Don't forget to start Furnace:
Future<Furnace> future = furnace.startAsync();
future.get(); // wait for Furnace to start, before continuing.
Once this is done, you'll now be able to request services from Furnace's AddonRegistry, and utilize the functionality of the addons you've installed:
MyServiceType instance = furnace.getAddonRegistry().getServices(MyServiceType.class).get();
Of course, addons can be pre-bundled into a project using the Furnace Maven Plugin, making it much simpler (and faster) to run your application:
<plugin>
<groupId>org.jboss.forge.furnace</groupId>
<artifactId>furnace-maven-plugin</artifactId>
<version>${version.furnace}</version>
<executions>
<execution>
<id>deploy-addons</id>
<phase>prepare-package</phase>
<goals>
<goal>addon-install</goal>
</goals>
<inherited>false</inherited>
<configuration>
<addonRepository>${basedir}/addon-repository</addonRepository>
<addonIds>
<addonId>org.example:my-addon,1.0.0.Final</addonId>
</addonIds>
</configuration>
</execution>
</executions>
</plugin>
