Getting spring status of Active bundle via JMX from Karaf 4.0.4

[Andrei Petru Mura]

Hello,

In Karaf 4.0.4, I have my own bundles deployed using spring-dm. I would be
interested if there is a possibility to get the status of a bundle via JMX
as it is listed in karaf console.

In karaf, I get this:
karaf@root> list

285 | Active   |  80 | 1.0.0.SNAPSHOT | bundle-name

>From my Java routine, I try to get the status via:

BundlesMBean mbeanProxy = JMX.newMBeanProxy(mbeanServer, bundlesObjName,
BundlesMBean.class, true);
TabularData tabularData = mbeanProxy.getBundles();

for (Object k : tabularData.keySet()) {
    // key from tabularData is a java.util.List
    Object[] key = ((List<?>) k).toArray();
    // CompositeData is a java.util.Map that hold properties
    // of a JMX entity
    CompositeData bundle = tabularData.get(key);
    String nameAttr = (String) bundle.get(BUNDLE_NAME_ATTR);
    String versionAttr = (String) bundle.get(BUNDLE_VERSION_ATTR);
    // checks if interested bundle
    if ( (nameAttr != null && nameAttr.equals("bundle-name"))
        && (versionAttr != null && versionAttr.equals("1.0.0.SNAPSHOT"))
    {
        // return bundle status taken as it is as java.lang.String
        // in karaf.
        return (String) bundle.get(BUNDLE_STATE_ATTR);
    }
}

The problem is that I always get null. Why this? and how can I make it so
that I get the Spring status?

Thanks,
Andrei
