This is driving me crazy. Any suggestions are appreciated.

My application has been compiling and running on Tomcat 7 for ages. I run it both directly from eclipse, and as a war file transferred to the Tomcat directory. The following error now occurs, whether I run the app from eclipse, or by copying over the war file.

The app has suddenly stopped running. The error message states that it can’t find the Weld Listener class. But the class is there, where it is expected, in .m2, and in the Tomcat webapp lib directory.

Here is the error:

Oct 15, 2012 12:28:00 AM org.apache.catalina.core.StandardContext listenerStart

You may need to add below dependency:
For Servlet Containers (Tomcat/Jetty)
or Java EE 5 Application Servers: Ref

<dependency>
    <groupId>org.jboss.weld.servlet</groupId>
    <artifactId>weld-servlet</artifactId>
    <version>1.1.10.Final</version>
</dependency>
