Hi Alex, do you have some publicly available project so that we can discuss a real code? In general, if you want to integrate Weld servlet with a custom servlet container: 1. Implement org.jboss.weld.environment.servlet.Container, e.g. GrizzlyContainer - Container#touch() should return true if a specific container is detected - Container#initialize() and Container#destroy() can be used to init/cleanup the container - note that ContainerContext#getManager() returns a BeanManager which could be used later, e.g. for dependency injection; you can also obtain a BeanManager from the servlet context - see for example [1] 2. Implement a container specific "injection support" - each servlet container should provide its own SPI - you should implement this SPI so that injection into servlets, listeners and filters is supported; see for example [2] how undertow support is implemented 3. There is no need to "connect" EnhancedListener in any way. It should be registeded automatically. However, if you're trying to run an embedded servlet container you will need to register org.jboss.weld.environment.servlet.Listener manually.
