Weld 1.1.1 and Tomcat7 problems

[uad.ulf.almehed.se]

When upgrading from Weld 1.1.0.Beta2 to 1.1.1.Final and Tomcat server from 7.0.6 to 7.0.14, my application stopped working. I get the following exception:

Any ideas? Workarounds?

Kind Regards,

This might be caused by the following bug:
https://issues.jboss.org/browse/WELD-879

The workaround mentioned in the comment section worked for me:

You can workaround the problem by placing proper org.jboss.weld.environment.Container file into your app's META-INF/services.

The file contains the text:

org.jboss.weld.environment.tomcat7.Tomcat7Container

In my setting the file is placed in:
WEB-INF\classes\META-INF\services\

Thanks for your reply. Unfortunately it doesn't seem to help in my case. I've tried every position of the file I can think of, but I still get the same exception when the application starts.

After changing to version 1.1.0.Final of Weld it works though, so it looks like this problem has been introduced in the latest release.

Kind Regards /Ulf

Did you notice the following line of the stacktrace:

at org.jboss.weld.environment.tomcat.Tomcat6Container.initialize(Tomcat6Container.java:47)

This fits well to the above mentioned bug (Tomcat 7 container is identified as Tomcat 6), that is reported for version 1.1.1 Final.

The class AnnotationProcessor seems no longer be part of Tomcat 7, as the changelog says:

Switch from AnnotationProcessor to InstanceManager.

In my project I can reproduce exactly the same exception, if i remove the file services\org.jboss.weld.environment.Container. Just like in your case, I ran into trouble after switching to version 1.1.1.

I wonder what is different in your setup...
