7.2. Manual Deployment

You can manually deploy and undeploy bundles by issuing commands at the Red Hat JBoss Fuse console.

Use the osgi:install command to install one or more bundles in the OSGi container. This command has the following syntax:

osgi:install [-s] [--start] [--help] UrlList

Where UrlList is a whitespace-separated list of URLs that specify the location of each bundle to deploy. The following command arguments are supported:

For example, to install and start the bundle, ProjectDir/target/foo-1.0-SNAPSHOT.jar, enter the following command at the Karaf console prompt:

osgi:install -s file:ProjectDir/target/foo-1.0-SNAPSHOT.jar

To uninstall a bundle, you must first obtain its bundle ID using the osgi:list command. You can then uninstall the bundle using the osgi:uninstall command (which takes the bundle ID as its argument).

For example, if you have already installed the bundle named A Camel OSGi Service Unit, entering osgi:list at the console prompt might produce output like the following:

...
[ 181] [Resolved   ] [            ] [       ] [   60] A Camel OSGi Service Unit (1.0.0.SNAPSHOT)

You can now uninstall the bundle with the ID, 181, by entering the following console command:

osgi:uninstall 181

When specifying the location URL to the osgi:install command, you can use any of the URL schemes supported by Red Hat JBoss Fuse, which includes the following scheme types:

In a development environment—where a developer is constantly changing and rebuilding a bundle—it is typically necessary to re-install the bundle multiple times. Using the dev:watch command, you can instruct Karaf to monitor your local Maven repository and re-install a particular bundle automatically, as soon as it changes in your local Maven repository.

For example, given a particular bundle—with bundle ID, 751—you can enable automatic redeployment by entering the command:

dev:watch 751

Now, whenever you rebuild and install the Maven artifact into your local Maven repository (for example, by executing mvn install in your Maven project), the Karaf container automatically re-installs the changed Maven artifact. For more details, see section "dev:watch, watch" in "Console Reference".
