Hello At first glance, it should be "Web-ContextPath", not "WebContext-Path". See https://docs.osgi.org/specification/osgi.cmpn/8.0.0/service.war.html#i3077053
And we actually have a Vaadin 8 example: https://github.com/ops4j/org.ops4j.pax.web/tree/pax-web-8.0.x/samples/samples-war/war-vaadin08 We also have a test that installs it as webbundle: WAB: https://github.com/ops4j/org.ops4j.pax.web/blob/e15cb08d433e2d500519b65f4a0cb7c273f4399a/pax-web-itest/pax-web-itest-container/pax-web-itest-container-common/src/main/java/org/ops4j/pax/web/itest/container/war/AbstractWarVaadin08IntegrationTest.java#L35 I remember ensuring that WebSockets work with Vaadin. But this was quite long time ago... kind regards Grzegorz Grzybek czw., 15 sty 2026 o 17:00 'Richard Hierlmeier' via OPS4J < [email protected]> napisał(a): > I have to upgrade a Vaadin 8 application from Karaf 4.3 (pax-web 7) to > Karaf 4.4.8 (pax-web 8). > > The OSGi bundle with the Vaadin application is a WAB. > It has a WebContext-Path defined in the OSGi header. > > The VaadinServlet sets up Atmosphere and tries to detect the WebSocket > support of the servlet engine.
