Do you have an exception?

I'm no expert in osgi, but this sounds more like an osgi problem than an Activiti one?

Yes. you are right, this looks like issue with Servicemix.
I had to add my bean in applicationContext.xml in activiti-explorer

eg : \apache-tomcat-6.0.35\webapps\activiti-explorer\WEB-INF\applicationContext.xml

But I was wondering, why we need to define our bean in here ?
I already define my bean inside my jar file.. Why activiti did not find the bean

The explorer app indeed boots its engine using that spring config file, it doesn't use the ProcessEngines class. That's the reason why it doesn't pick up the engine config.
