Weld 2.1.0.Final and Tomcat 7 [Problem]

Good night Friends,

I configured my project to work with Weld 2.1.0.Final and Tomcat 7 but a problem ocurred:

Could someone help me?

Some places say the Weld recognizes Tomcat 7 like Tomcat 6. is this it?

Hi Luiz,

I think there must be some other problem. If you look at the stack trace - lines 10-11, Tomcat fails to start (most probably before Weld is fully initialized) and then tries to stop correctly and invokes contextDestroyed() on WeldInitialListener which is not in a valid state. In any case this NPE is not a cause but rather a consequence. I would try to search all log files for the real cause.
