Hello!
I've been playing with apache felix for some months. Now I am building
a bundle that depends on external jars and use a bit of reflection.
To overcome the problem of the external library I have used the
Bundle-ClassPath: manifest header.
Currently my problem is when I tried to load a class using reflection
and I get a class not found exception.
javax.management.ReflectionException: The MBean class could not be
loaded by the default loader repository
at
com.sun.jmx.mbeanserver.MBeanInstantiatorImpl.findClassWithDefaultLoaderRepository(MBeanInstantiatorImpl.java:61)
at
com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.createMBean(DefaultMBeanServerInterceptor.java:271)
at
com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.createMBean(DefaultMBeanServerInterceptor.java:211)
at
com.sun.jmx.mbeanserver.JmxMBeanServer.createMBean(JmxMBeanServer.java:408)
at kAdapt.mbeanServer.MainServer.registerMBean(MainServer.java:131)
Caused by: java.lang.ClassNotFoundException: kAdapt.mbeanServer.InfoMBean
at
com.sun.jmx.mbeanserver.ClassLoaderRepositorySupport.loadClass(ClassLoaderRepositorySupport.java:208)
at
com.sun.jmx.mbeanserver.ClassLoaderRepositorySupport.loadClass(ClassLoaderRepositorySupport.java:128)
at
com.sun.jmx.mbeanserver.MBeanInstantiatorImpl.findClassWithDefaultLoaderRepository(MBeanInstantiatorImpl.java:58)
... 18 more
The class in question kAdapt.mbeanServer.InfoMBean is of course in the
package hierarchy but the osgi classloader seems to miss it ...
I would like to know why this happens and the solution.
( In this particular problem the class failing to load is an MBean when
trying to create it
-->> at
com.sun.jmx.mbeanserver.MBeanInstantiatorImpl.findClassWithDefaultLoaderRepository(MBeanInstantiatorImpl.java:61)
but I think that this problem will happen whenever one uses reflection
... Am I right ?
)
I tried with DynamicImport-Package but without success too ...
Here is my manifest
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Build-Jdk: 1.5.0_12
Bundle-Activator: kAdapt.Activator
DynamicImport-Package: kAdapt.mbeanServer <<---- the class not found
is here
Bundle-ClassPath: .,kAdapt,js-1.6R5.jar
Import-Package: org.osgi.framework;version=1.3,org.osgi.service.log;ve
rsion=1.3,javax.management.remote,javax.management,javax.xml.parsers,
org.w3c.dom,org.xml.sax
Bundle-ManifestVersion: 2
Any guidance will be greatly appreciated.

PS: I think I could use the jmx facilities provided by felix ( I am
already doing that in another bundle, but that is not the point in my
question....))
