Embedded Felix in a web application
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)
java.lang.Error: factory already defined
at
java.net.URL.setURLStreamHandlerFactory(URL.java:1076)

at
org.apache.felix.framework.util.SecureAction.startActivator(SecureAction.java:589)
at
org.apache.felix.framework.Felix.start(Felix.java:703)
Is there specific configuration to do in order to
embed Felix in a web application?
Thanks a lot for your help?

Thanks Karl and Richard for your help!
It solves my problem. This latter occurs only when I
try to use Felix in an embedded mode in a Eclipse
Dynamic Web Project with Web Tools Platform. I works
correctly in a simple Java project...

Also, we have plans to add support for replacing (and delegating) to
existing URL handler factories too, but for now you will need to disable
the framework's factory.

You need to disable the URLHandler by setting the
felix.service.urlhandlers property to false in the config.properties
file.
