Hello, I have about 30 servlet contexts (ServletContextHelper) scattered across multiple bundles. One of these context (WebviewerServletContextHelper) has "osgi.http.whiteboard.context.path=/". I also have one bundle containing all servletFilters for these servlet contexts. These filters mostly for session manipulation and security checks so If the request does not pass through these filters, it will cause exception when arriving at the servlet. Thus, i want to use ServiceUnavailableFilter from healthcheck to make sure that my filters (and other components) are ready before accepting http requests. I made the config file for ServiceUnavailableFilter as follow:
osgi.http.whiteboard.filter.regex=(?!/system/).* osgi.http.whiteboard.context.select=(osgi.http.whiteboard.context.name =WebviewerServletContextHelper) tags=systemalive responseTextFor503=Service Unavailable, wait.. wait... wait.... service.ranking=1 avoid404DuringStartup=true I set service.ranking=1 because i'm running pax-web and it seems to execute filters in ascending ranking. I also set avoid404DuringStartup=true and start level of healthcheck.core to level 3 (default is 4) because I want this filter to be up before my servlets and filters (default level 4). However, I always see "INFO o.a.f.h.c.i.f.ServiceUnavailableFilter - ServiceUnavailableFilter active (start level 4)" which indicates the component has been activated but the ServiceUnavailableFilter never process any request. So here are some questions 1. In a dynamic env like osgi container, how can we be sure that a request always be processed by a filter before arriving at the servlet? Bundles do not always start in the same order thus a filter may be registered after the servlet it supposed to protect 2. Even when i waited for a long period after starting my server and healthcheck return OK for all of my checks, why does ServiceUnavailableFilter not handle any request? About my env, I'm using org.apache.felix.healthcheck.annotation_2.0.0 org.apache.felix.healthcheck.api_2.0.0 org.apache.felix.healthcheck.core_2.0.6 org.apache.felix.healthcheck.generalchecks_2.0.4 and pax-web 7.2.4 in equinox (org.eclipse.osgi_3.12.0.v20170512-1932) Hope someone can shed a light Thai
