The first developer version jmx4perl 0.55_1 with OSGi support has been pushed to CPAN.
New year, new features: jmx4perl is going to provide support for OSGi. If you ask yourself what the heck is OSGi, in brief, OSGi is a Java platform for modules, so called bundles. It provides support for runtime dependency management, module lifecycle support and intra-VM services. Most of the newest Java application servers are based on an OSGi kernel. A good introduction to OSGi can be found here.
The just released development version 0.55_1 contains the OSGi-Bundle j4p-osgi-0.55.0.M1.jar, which can be deployed on an arbitrary OSGi platform (Felix and Equinox has been tested). The only dependency is on an OSGi HttpService for which various implementations exist. The bundle will be reachable under the context j4p/.
For a quick start, here is a sample session using Pax Runner as launcher (it is assumed, that you have it installed and pax-run is in your path). pax-run should be called with the j4p-osgi-0.55.0.M1.jar bundle as argument:
$ pax-run --profiles=core,compendium,web j4p-osgi-0.55.0.M1.jar

->In a second terminal session, fireup jmx4perl to connect to the exported bundle e.g. with
jmx4perl http://localhost:8080/j4p listAuthentication is implemented as well (and will be documented in the final release). Although the regular agent war could be deployed with the help of a WebApp-Extender, this bundle provides a more lightweight approach.
In addition to the new OSGi stuff, the Perl API will be extended for 0.55 to allow for listing and querying the attributes of an individual bean.
In parallel, I started a new project called osgish, which aims to provide a readline based shell for OSGi with help of jmx4perl and Aries, an implementation of the forthcoming OSGi Enterprise Expert Group (EEG) specification (Early Draft 4). The JMX bundle of Aries exports most management commands via JMX.
