I'm not sure what you are trying to find out: there are at least
three possible states for a module
- in the repo
- loaded in the kernel
- running.
First you need a kernel. If your code is in a gbean you can get it
as a gbean attribute. Otherwise you can use
KernelRegistry.getSingleKernel() (unless you are running more than
one kernel in the vm, something I think no one has done yet)
Then
ConfigurationManager configurationManager =
ConfigurationUtil.getConfigurationManager(kernel);
Artifact moduleId = Artifact.create("mycom/myapp/1.0/car");
configurationManager.isInstalled(moduleId);
configurationManager.isLoaded(moduleId);
configurationManager.isRunning(moduleId);
Another approach in a gbean is to have a collection valued reference
of type Configuration and put the name of the desired configuration
in the plan: then your code can check the cardinality of the
collection to see if the other configuration is running.

Is there a way to ask the Geronimo container whether or not a specific
module (by name) is deployed. I'd like to do something like
String moduleId = "mycom/myapp/1.0/car";
if (moduleExists(moduleId) {
doSomething();
} else {
doSomethingElse();
}
Possibly the class
org.apache.geronimo.kernel.repository.DefaultArtifactResolver will
provide
this functionality, but I have fiddled with it a bit and it doesn't
seem
immediately apparent exactly how to use it.
Thanks all...
