Apache Felix Web控制台

Question

Trying to install Apache Felix Web Console at felix-4.6.1 .

I typed deploy -s "org.apache.felix.webconsole"

And what I get is:

And my listed bundles are:

When I go to http://localhost:8080/system/console the page is loaded and I can see the web console. So why do I get the above exception? Should I worry about it?

UPDATE

I did a fresh install of the framework and now everything works fine without any exceptions. After running deploy -s "org.apache.felix.webconsole" I get:

Target resource(s): 
    Apache Felix Web Management Console (3.1.2)
Required resource(s):
    Apache Felix Configuration Admin Service (1.2.4)

    OSGi R4 Compendium Bundle (4.0.0)    
    Apache Felix iPOJO WebConsole Plugins (1.6.0)  
    Apache Felix Log Service (1.0.0)  
    Apache Felix Shell Service (1.4.2)  
    Deploying... 
    [INFO] Started bridged http service done.

This got me curious and I remembered that I had added my local Maven repository.xml as an OBR repository (at config.properties file) besides the default one.

So I went back to the old installation and run: g! list equi g! list equi and I got

When I removed the local Maven OBR everything worked fine. So now the question could become: why don't the dependencies get resolved correctly in the first place?

Answer 1

The error is caused by the org.eclipse.osgi "OSGi System Bundle", which kind of sounds like you are loading the Equinox OSGi framework inside Felix. If that is the case, you should just remove that bundle.
