Using the jmxmp jmx remote protocol in OSGi
I am porting some jmx code to karaf.
The code wants to offer a remote jmx connector using the jmxmp protocol.
This is implemented in the jmxremote_optional.jar in the jdk.
The problem is that the jmx impl scans the class path META-INF/services
for protocol implementations. This does not work in OSGi.
So I guess I either have to tweak the classpath or have to add the
protocol programmatically.
Did anyone already do one of the variants for remote jmx and can help me
get this working?

Hi Christian,
Some work has been done getting ServiceLoader working in an OSGi context,
see
http://coderthoughts.blogspot.com/2011/08/javautilserviceloader-in-osgi.htmlwhich
links to the Aries project. Might help.
cheers,
Caspar

If all you need to do is use the JMXMP connector from within OSGi, and you
don't care about dynamic support for other protocols, here's a really simple
solution that I am using. Simply make sure your copy of
jmxremote_optional.jar has proper OSGi headers in its manifest, add that jar
as a plug-in to your project, and in the code that creates your JMX
connector server, add this:
Map<String, Object> env = new HashMap<String, Object>();
env.put(JMXConnectorServerFactory.PROTOCOL_PROVIDER_PACKAGES,
"com.sun.jmx.remote.protocol");
When you invoke JMXConnectorServerFactory.newJMXConnectorServer, provide the
above map as the second argument.
You can use the same thing for creating a connector client with
JMXConnectorFactory.newJMXConnector().

Hi Christian,
The normal java SPI mechanism doesn't work in OSGi container, so in
Servicemix we wrap some spec bundle which need use SPI to find the
implementations by using OSGiLocator.
You can find the OSGiLocator code here[1], and an example how a spec
bundle use this OSGiLocator[2]
[1]https://svn.apache.org/repos/asf/servicemix/smx4/specs/trunk/locator/
