Hello and thank you for a quick response!

Sorry, I forgot to include the versions. I am running Apache Karaf 4.4.1 which 
comes with Pax Web 8.0.6.

I looked at the samples and they already helped me a lot but I will look at 
them once again, maybe I missed something. Basically, I followed: 
https://github.com/ops4j/org.ops4j.pax.web/blob/web-8.0.11/samples/samples-jsf/war-primefaces-wired/pom.xml





You actually don't uninstall features using karaf-maven-plugin - you declare 
features you want, and karaf-maven-plugin will put the features into boot 
features (etc/org.apache.karaf.features.cfg - when in runtime scope) or into 
startup bundles (etc/startup.properties - when in compile scope). So definitely 
you have to fix your <configuration> for karaf-maven-plugin.



I have the following dependencies in my pom.xml (used to build custom Karaf 
distribution)

And I listed the following features in startupFeatures:

              <startupFeature>config</startupFeature>

                                                                                
              <startupFeature>http</startupFeature>

                                                                                
              <startupFeature>webconsole</startupFeature>

                                                                                
              <startupFeature>pax-web-http-tomcat</startupFeature>

                                                                               
</startupFeatures>

This results in the above declared features listed in bootFeatures in 
etc/org.apache.karaf.features.cfg.

When I start Karaf with this set up without my application the webconsole works 
fine and I can see the following on the features page:

pax-web-http-jetty         8.0.6      org.ops4j.pax.web-8.0.6              
Installed

pax-web-http-tomcat    8.0.6      org.ops4j.pax.web-8.0.6              Installed

Therefore I asked whether it i possible to uninstall pax-web-http-jetty.



2nd - how do you install the webconsole and/or your JSF bundle? Are then 
installed as WAR (WAB) files? May I see them? I don't claim that the problem is 
only at your side - maybe Pax Web didn't anticpate some setup and I'd be happy 
to help solving this problem.



Webconsole is listed in the bootFeatures (see above). My application consists 
of a lot of bundles but the one with the UI is a WAB (war packaging with 
manifest which includes: Web-ContextPath: /main). Primefaces and JSF are wired 
using the Require-Bundle header in manifest:

<Require-Bundle>

javax.faces-api,

org.primefaces

</Require-Bundle>

All the bundles and their dependencies (JSF, primefaces etc.) are listed in a 
feature.xml file which I place in the deploy directory in Karaf. The 
application loads and works fine. I am just having problem with the webconsole.

I unfortunately cannot share the code of the bundles. But I am happy to provide 
more information if necessary.



Let me know if you need more information.

Best regards

Hello



First - which Karaf version are you using?

Assuming it's Karaf 4.4.x with Pax Web 8.0.x I can try helping.



Pax Web 8 is highly refactored major version of the project where we've tried 
to make sure that things like JSF (which rely heavily on 
ServletContainerInitializers) work smoothly.

There are dedicated tests both for webconsole and for JSF (MyFaces, Primefaces) 
and even for techs like Vaadin.



Check the JSF samples at 
https://github.com/ops4j/org.ops4j.pax.web/tree/web-8.0.11/samples/samples-jsf



Is it possible that the behavior is caused by conflict between 
pax-web-http-jetty and pax-web-http-tomcat? Is there a way how to uninstall 
pax-web-http-jetty using karaf-maven-plugin?

Hello everyone,
I am experiencing strange behavior with webconsole of Apache Karaf. I have an 
application deployed using a custom feature file in Apache Karaf. The 
application is based on Spring and is using Primefaces (and Mojarra JSF 
implementation version 2.2.15). When I run it with standard war feature (which 
by default installs pax-web-http-jetty) I am getting the following error 
messages in the log file:
Unable to obtain InjectionProvider from init time FacesContext. Does this 
container implement the Mojarra Injection SPI?
Unable to inject com.sun.faces.application.ApplicationFactoryImpl@5005965f 
<mailto:com.sun.faces.application.ApplicationFactoryImpl@5005965f>  because no 
InjectionProvider can be found. Does this container implement the Mojarra 
Injection SPI?
However, the webconsole works perfectly in this case.
When I install the pax-web-http-tomcat feature the above mentioned error 
messages are gone but the webconsole is not working properly (the resources 
from res and lib are not loaded so I see allmost an empty page - see 
attachment).
I can see the following errors in the log file:

Does it mean that the webconsole works only with pax-web-http-jetty?

I can also see that both pax-web-http-jetty and pax-web-http-tomcat features 
are installed. Is it possible that the behavior is caused by conflict between 
pax-web-http-jetty and pax-web-http-tomcat? Is there a way how to uninstall 
pax-web-http-jetty using karaf-maven-plugin?
Any help with this issue will be appreciated.
