We move html to src/main/webapp. The folder content will be configured to be placed in bundle root (build config). So we also put blueprint.xml file there.

mkdir -p src/main/webapp/OSGI-INF/blueprint
vim src/main/webapp/OSGI-INF/blueprint/blueprint.xml

cat src/main/webapp/OSGI-INF/blueprint/blueprint.xml 
<blueprint default-activation="eager"
    xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 
    <bean id="resourceMapping"
        class="org.ops4j.pax.web.extender.whiteboard.runtime.DefaultResourceMapping">
        <property name="alias" value="/" />
        <property name="path" value="" />
    </bean>
 
    <bean id="welcomeFile"
        class="org.ops4j.pax.web.extender.whiteboard.runtime.DefaultWelcomeFileMapping">
        <property name="redirect" value="true" />
        <property name="welcomeFiles">
            <array>
                <value>index.html</value>
            </array>
        </property>
    </bean>
 
    <service id="resources" ref="resourceMapping"
        interface="org.ops4j.pax.web.extender.whiteboard.ResourceMapping" />
 
    <service id="welcomeFileService" ref="welcomeFile"
        interface="org.ops4j.pax.web.extender.whiteboard.WelcomeFileMapping" />

Configure bundle root

  <_wab>src/main/webapp/</_wab>

This means everything in src/main/java is compiled and put in WEB-INF/classes. Everything in src/main/resources is put in WEB-INF/classes. This is pretty much what you would expect because these locations are used to put files that are loadable via the classloader. The content in src/main/webapp is then placed in the root. In fact in this scenario you put the web.xml in the src/main/webapp/WEB-INF directory, and if your WAB contains blueprint your blueprint would go in src/main/webapp/OSGI-INF/blueprint.
