Hi, I think you need to export the package of your class.
Your manifest should include something like: Export-Package: org.damiox.test.bundle2 regards, Michiel ----------------- http://www.codessentials.com - Your essential software, for free!

This bundle contains only 1 class: org.damiox.test.bundle2.HelloWorld. The blueprint xml file (OSGI-INF/blueprint/config.xml) is detailed below: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";> <bean id="helloWorld" class="org.damiox.test.bundle2.HelloW2orld" init-method="niam"> </bean> </blueprint> And the MANIFEST.MF is the following: Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Bundle2 Bundle-SymbolicName: Bundle2 Bundle-Version: 1.0.0.qualifier Import-Package: org.osgi.framework Bundle-ClassPath: . Bundle-RequiredExecutionEnvironment: J2SE-1.5 I'm running the JBoss Server through Eclipse Juno and starting my bundle from there. Why is it failing? This is driving me nuts :) Regards Damian
