Hello,
I have problems to embed a felix (version 1.0)
container in a java web application deployed on a
Tomcat server (version 5.5).
In order to start/stop the container, I use a
ServletContext listener as follow:
public class WebAppListener implements
ServletContextListener {
private OsgiManager osgiManager = new
FelixManager();
public void contextInitialized(ServletContextEvent
context) {
osgiManager.initOsgi();
}
public void contextDestroyed(ServletContextEvent
context) {
osgiManager.destroyOsgi();
}
}
and the code of the initOsgi method is:
public void initOsgi() {
Map configMap = new StringMap(false);
configMap.put(FelixConstants.EMBEDDED_EXECUTION_PROP,
"true");
configMap.put(Constants.FRAMEWORK_SYSTEMPACKAGES,
"org.osgi.framework; version=1.3.0," +
"org.osgi.service.packageadmin;
version=1.2.0," +
"org.osgi.service.startlevel;
version=1.0.0," +
"org.osgi.service.url; version=1.0.0");
configMap.put(BundleCache.CACHE_PROFILE_DIR_PROP,
"cache");
try {
List activators = new ArrayList();
initActivator = new InitActivator();
activators.add(initActivator);
felixContainer = new Felix(configMap, activators);
felixContainer.start();
} catch(Exception ex) {
ex.printStackTrace();
}
I have the following error when the webapp starts:
ERROR: Unable to start system bundle.
(java.lang.Error: factory already defined)

Is there specific configuration to do in order to
embed Felix in a web application?
Thanks a lot for your help?
