class loading exception in 1.1 RC1 OSGi on Felix

[ingo-23]

Hi,

I'm currently testing EasyBeans on the current Apache Felix, and do get class
loading exceptions on the Agent start:

(only the relevant excerpt)

ERROR: Error starting obr://org.ow2.easybeans.agent/1243265793390
(org.osgi.framework.BundleException: Activator start error in bundle
org.ow2.easybeans.agent [28].)
org.ow2.util.xmlconfig.XMLConfigurationException: Cannot build an instance of
class 'org.ow2.easybeans.component.jotm.JOTMComponent' using classloader
'15.0'.        at
org.ow2.util.xmlconfig.XMLConfiguration.newInstance(XMLConfiguration.java:507)
....
Caused by: java.lang.ClassNotFoundException: javax.transaction.SystemException
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(Unknown Source)

Package "javax.transaction" is marked for export in EasyBeans Core, but not for
import in the EasyBeans Agent (as least thats what felix reports on "exports"
and "imports"). Am I missing something, or are the current bundles really not
functional?

Other question: I did not find any OSGi build targets, can you give me any
pointer where to look and build the OSGi bundles myself?

Regards,
Ingo

hi Ingo,

 

  for build, i think you can use  Bnd(http://www.aqute.biz/Code/Bnd
) tools which is developed by Peter.Kriens@... .

    Hi,

Check that in your Apache Felix configuration file, the
javax.transaction package is not listed as a system packages
(org.osgi.framework.system.packages) else it will use the package from
the JDK and this package doesn't contains all the JTA classes. (there
are configuration files for Felix/Equinox/etc provided in the
EasyBeans/OSGi assembly)

On EasyBeans/OSGi source code, run the "mvn clean install" command and
it will produce the EasyBeans OSGi bundles.

Florent
