> Key: KARAF-7400
> URL: https://issues.apache.org/jira/browse/KARAF-7400
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.3.6
> Reporter: Mariano Eloy Fernández
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Attachments: spring.boot.demo.three.zip
>
>
> I am following the steps on
> https://karaf.apache.org/manual/latest/webcontainer to deploy a simple Spring
> Booot WAR.
> I download the Spring Booot sample from https://start.spring.io/ and {{mvn
> install it}}.
> Then I execute:
> {code}
> bundle:install -s
> "webbundle:mvn:org.example.osgi/spring.boot.demo.three/0.0.1-SNAPSHOT/war?Bundle-SymbolicName=demo-three&Web-ContextPath=/three"
> {code}
> I get this error:
> {code}
> 10:31:34.124 INFO [paxweb-extender-1-thread-1] will add
> org.apache.jasper.servlet.JasperInitializer to ServletContainerInitializers

> application
> java.lang.NullPointerExceptio
> {code}
> There is no hint on what is causing this {{NullPointerException}}. I tried to
> {{log:set TRACE}} but it still gives no further information.
> My ultimate goal is to deploy several Spring Boot apps as WARs to let Karaf's
> Jetty route calls to these apps based on their {{context-path}}.
