以编程方式将捆绑软件部署到OSGI运行时

Question

I have a system setup where I am running Eclipse Equinox in a server-side application and in my Eclipse RCP Application. My goal is to take a plugin in the workspace and deploy it into the server-side app and I'm not sure how to go about it.

I know OSGI supports runtime bundle installs but would I have to compile my workspace project into a jar first? Is there an API I can use in Eclipse Runtime to say ..installBundle(String pathToJar or pathToProject) ?

Answer 1

This is an example I tested on eclipse equinox. If "plugins" is the name of the folder containing all your osgi bundles, a method to install and start a bundle from there is:

void installAndStartBundle(String bundlName) throws BundleException{
    BundleContext bundlecontext = FrameworkUtil.getBundle(this.getClass()).getBundleContext();
    Bundle b = bundlecontext.installBundle("file:plugins" + File.separator + bundleName);
    b.start();
}

where bundleName is the name with jar extension of the deployable bundle.

This is equivalent to the instructions from the osgi console

install file:plugins/<bundle name>.jar
start <bundle id>

In general, you might want to consider Apache Felix File Install as a more robust option.
