Yes OWB in TomEE works just fine. Outside TomEE a SCI is kind of "the standard" of extending a web container although there are some unclarified areas as the order of execution. For instance Mark Thomas used this approach with websocket implementation in tomcat. Still it is tempting to try this. > Romain Manni-Bucau > Twitter: @rmannibucau > Blog: http://rmannibucau.wordpress.com/ > LinkedIn: http://fr.linkedin.com/in/rmannibucau > Github: https://github.com/rmannibucau > > > > 2013/11/9 Mark Struberg <[email protected]>: > > Hi Niki! > > > > Karl and I did already work on improving our documentation at least ;) > > > > http://openwebbeans.apache.org/owbsetup_ee.html > > > > Please ping us if you find a failure! > > > > LieGrue, > > strub > > > > > > ________________________________ > > From: Niki Dokovski <[email protected]> > > To: [email protected]; 'Mark Struberg' > <[email protected]> > > Sent: Saturday, 9 November 2013, 15:01 > > Subject: RE: OWB on Tomcat 7 > > > > Hi Mark, > > > > From: Mark Struberg [mailto:[email protected]] > > Sent: Saturday, November 9, 2013 3:25 PM > > To: [email protected] > > Subject: Re: OWB on Tomcat 7 > > > > Hi folks! > > > > There are 2 different ways to work with OpenWebBeans and tomcat. > > > > > > > > A, your app is using CDI but you do not need the container to > > understand CDI. > > In that case just add owb-core jar + spi + xbean-asm4-shaded + owb-web > > into your WEB-INF/lib and add WebBeansConfigurationListener to your > > web.xml as <listener> > > > > This works perfect, but be aware that there is no CDI injection in > > Servlets themself.
