Hello, Thank You for Your answer.
I’ve given up the way of adapting pax-web. Instead I’ve modified com.eclipsesource.jaxrs-publisher, so that it binds SessionListeners to Pax-Web HttpContext, then everything works within single-context principle. Now we have branch of the project that can work only with pax-web, but supports session listeners.

That means it's like with a WAR you only have one web context. regarding the documentation it's either in the confluence or asciidoc, everything else is in the sources. regards, Achim 2017-07-04 9:52 GMT+02:00 Lukasz Lech <[email protected]<mailto:[email protected]>>: Hello, OK, I’ve got an ‚error‘ in corporate maven settings – everything was mirrored by single server. Now I get NullPointerException in tests: java.lang.NullPointerException at org.ops4j.pax.web.service.spi.model.ServerModel.lambda$deassociateHttpContexts$1(ServerModel.java:394) I’ve looked on the collection involved: /** * Map between http contexts and the bundle that registred a web element * using that http context. Used to block more bundles registering web * The map is wrapped into map for virtual hosts. * elements using the same http context. */ private final ConcurrentMap<String,ConcurrentMap<WebContainerContext, Bundle>> httpContexts; This what makes me worried about is the bolded fragment of Javadoc. I have bad feeling that many developers were fixed on the idea that web context is used only by one bundle and it might not be possible to change that by switching one factory method implementation. Is there any documentation on how the HttpContext mechanismus is supposed to work, or examples by many bundles sharing one context?

As for integration tests, I haven’t checked – which module is that? I’ll have a look. I’ve got generally issues getting that thing to compile. Issuing ‘mvn install’ in project root did not work, because some modules are referenced, but not listed in root pom (pax-web-tomcat AFAIR). It should be easy to replicate via build against clean local maven repository with non-modified settings.xml (Gitlab CI build, for example). I don’t know if it’s by-design or not… I’ve got to run mvn install to install parent pom, and then do mvn install for individual modules to get things to work. I’ll take a look on the samples, but as I see, those are separate modules. Are there any tests for many modules cooperating (for example, separate WebService servlet, separate authentication filter)? As for your path, I’ve tried to apply it via ‘git apply PAXWEB-1105.diff’ both on master and my branch (https://github.com/llech/org.ops4j.pax.web/tree/PAXWEB-1105) but I’ve failed with following error message: D:\Projects\libs\org.ops4j.pax.web>git apply ..\..\PAXWEB-1105_improved.diff ..\..\PAXWEB-1105_improved.diff:12: space before tab in indent.

As for DefaultSharedWebContainerContext, I was debugging a bit and I’ve found a place where the HttpContext was used as a key in HashMap: org.ops4j.pax.web.service.jetty.internal.JettyServerWrapper (contexts). Because the class had no equals/hashCode, even If after my patch, createDefaultHttpContext has created SharedContext, for this map those were distinct keys, so different ServletContextInfo was returned. However, adding equals/hashCode has not solved my issue. Apart for error because of HttpServiceStarted (line 1161, instanceof should be called for context, not httpContext?), it seems that BundleContext is used much deeper as a key. My all attempts, anyway, are in my fork of repository on GitHub. Best regards, Lukasz Lech From: 'Achim Nierbeck' via OPS4J [mailto:[email protected]<mailto:[email protected]>] Sent: Sonntag, 2.

All integration tests are failing though, so it seems your changes aren't complete. Might that be the reason your own tests aren't working correctly? regards, Achim 2017-06-30 22:57 GMT+02:00 Achim Nierbeck <[email protected]<mailto:[email protected]>>: Hi Lukasz, this is definitely the right list to ask for. Right now I don't have much time or energy to look at your issue in a closer detail. If in doubt about how a shared context is about to work, please take a look at the samples and / or the integration tests. There are some available and I hope they make some of your questions clearer. If not I might have some more free cycles and a clearer mind about that next week ... regards, Achim 2017-06-30 11:23 GMT+02:00 Lukasz Lech <[email protected]<mailto:[email protected]>>: Hello, I hope this group is appropriate for asking this question, if not, my apologize and please suggest if there is appropriate place to ask.

I’ve set a breakpoint within org.eclipse.jetty.server.session.AbstractSessionManager.addSession(AbstractSession, boolean) and _sessionListeners list is empty. Do I get something conceptually wrong? I thought that if both bundles will register stuff using the same HttpContext, one of them could register listener that would listen to events for servlets created by the second one. Is the concept of bundles working with different HttpContext somehow deeply build-in in pax-web so I can’t change that behavior with such simple ‘hack’? Anyway, my patch (after cleanup – I’ve increased log level to see what happens and commented out the baselining so that I’m able to compile with maven) seems to solve the JIRA issue. However I’m not sure if the JIRA issue solves any issue, or I lack understanding the concept of ‘shared’ and ‘non-shared’ HttpContext in pax-web….
