It would be really cumbersome to get something meaningful from the log file when running with my application.

When I start Karaf it loads successfully but when I try to access /system/console page I get the already mentioned error in the log file.

Webconsole is listed in the bootFeatures (see above). […] Actually, it's specified in <startupFeatures> :) that's big difference - you're effectively doing (karaf-maven-plugin is doing) the resolution at build time, so you simply get a big list of bundles inside etc/startup.properties. This makes uninstalling the features a bit harder. In other words - "<startupFeatures>" vs. "<bootFeatures>" is like bundle vs feature. With "startup features" you're "flattening" the features into a list of bundles. It may speed things up, but generally I'm not recommending it. And finally, to see what's the problem, you can increase logging level of "org.ops4j.pax.web.extender.war" (to DEBUG or even TRACE) to get a lot of information about ServletContainerInitializers and annotated classes being discovered. I still hope that removing pax-web-http-jetty (by not including "http" feature) will solve your problem. regards Grzegorz Grzybek czw., 3 lis 2022 o 10:36 Martin Zukal via user <[email protected] <mailto:[email protected]> > napisał(a): Hello and thank you for a quick response!

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) <dependency> <groupId>org.apache.karaf.features</groupId> <artifactId>framework</artifactId> <version>${karaf.version}</version> <type>kar</type> </dependency> <dependency> <groupId>org.apache.karaf.features</groupId> <artifactId>framework</artifactId> <version>${karaf.version}</version> <classifier>features</classifier> <type>xml</type> <scope>runtime</scope> </dependency> <dependency> <groupId>org.apache.karaf.features</groupId> <artifactId>standard</artifactId> <version>${karaf.version}</version> <classifier>features</classifier> <type>xml</type> <scope>runtime</scope> </dependency> And I listed the following features in startupFeatures: <startupFeatures> <startupFeature>framework-logback</startupFeature> <startupFeature>instance</startupFeature> <startupFeature>package</startupFeature> <startupFeature>log</startupFeature> <startupFeature>ssh</startupFeature> <startupFeature>system</startupFeature> <startupFeature>feature</startupFeature> <startupFeature>shell</startupFeature> <startupFeature>management</startupFeature> <startupFeature>service</startupFeature> <startupFeature>jaas</startupFeature> <startupFeature>deployer</startupFeature> <startupFeature>diagnostic</startupFeature> <startupFeature>wrap</startupFeature> <startupFeature>bundle</startupFeature> <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.

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.

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: [2022-11-03 09:29:26.358] INFO tp-nio2-0.0.0.0-8080-exec-10 o.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/] Marking servlet [default-56ee4de3-f9f8-44c8-96ea-4580393e6469] as unavailable [2022-11-03 09:29:26.360] ERROR tp-nio2-0.0.0.0-8080-exec-10 o.a.c.c.C.[.[.[/].[default-56ee4de3-f9f8-44c8-96ea-4580393e6469] Allocate exception for servlet [default-56ee4de3-f9f8-44c8-96ea-4580393e6469] javax.servlet.UnavailableException: No static resources were found at org.apache.catalina.servlets.DefaultServlet.init(DefaultServlet.java:384) at org.ops4j.pax.web.service.tomcat.internal.web.TomcatResourceServlet.init(TomcatResourceServlet.java:87) at javax.servlet.GenericServlet.init(GenericServlet.java:180) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1164) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:804) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:128) at org.ops4j.pax.web.service.tomcat.internal.PaxWebStandardWrapperValve.invoke(PaxWebStandardWrapperValve.java:50) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:97) at org.ops4j.pax.web.service.tomcat.internal.PaxWebStandardContextValve.invoke(PaxWebStandardContextValve.java:98) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:135) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:92) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:78) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:360) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:399) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:65) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:890) at org.apache.tomcat.util.net <http://org.apache.tomcat.util.net> .Nio2Endpoint$SocketProcessor.doRun(Nio2Endpoint.java:1701) at org.apache.tomcat.util.net <http://org.apache.tomcat.util.net> .SocketProcessorBase.run(SocketProcessorBase.java:49) at org.apache.tomcat.util.net <http://org.apache.tomcat.util.net> .AbstractEndpoint.processSocket(AbstractEndpoint.java:1190) at org.apache.tomcat.util.net <http://org.apache.tomcat.util.net> .Nio2Endpoint$Nio2SocketWrapper$2.completed(Nio2Endpoint.java:633) at org.apache.tomcat.util.net <http://org.apache.tomcat.util.net> .Nio2Endpoint$Nio2SocketWrapper$2.completed(Nio2Endpoint.java:611) at java.base/sun.nio.ch.Invoker.invokeUnchecked(Unknown Source) at java.base/sun.nio.ch.Invoker$2.run(Unknown Source) at java.base/sun.nio.ch <http://sun.nio.ch> .AsynchronousChannelGroupImpl$1.run(Unknown Source) at org.apache.tomcat.util.threads.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1191) at org.apache.tomcat.util.threads.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:659) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Unknown Source) 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. Best regards Martin Zukal
