Hi,
let me try to summarize your situation (correct me if I am wrong):

1. you have generated the C3 project before the fix for COCOON3-105 
(that removed the default support for blockcontext:/)
2. recently you have re-built this project, Maven re-downloaded the 
latest versions of C3 SNAPSHOT artifacts (containing the fix for 
COCOON3-105, hence not working by default with blockcontext;/ stuff); 
with these new dependencies, you started getting error messages about 
classes not found

At this point you have two options:

(a) stuck with blockcontext:/ stuff: simply re-add this dependency in 
the webapp (i.e. the Maven submodule project that collects all blocks)

<dependency>
<groupId>org.apache.cocoon</groupId>
<artifactId>cocoon-block-deployment</artifactId>
<version>1.2.1</version>
</dependency>

(b) adapt your project to the new structure: the easiest path to achieve 
this is to generate an empty project (or take mine [1] as reference) and 
start changing / removing / adding things in your project by taking the 
empty one as reference.

My guess is that you are in the middle of (b); however, (a) is by far 
easier and quicker. The choice is up to you.

I must correct you, C3 is not yet in "beta" phase: the latest stable 
release is still "alpha", as the disclaimer says at

http://cocoon.apache.org/3.0/alpha-warning.html

You would be using the stable, e.g. not changing over time, C3 artifacts 
if your C3 version was 3.0.0-alpha-3.

Instead, you are using the 3.0.0-beta-1-SNAPSHOT artifacts, which are 
more cool because embed all latest fixes and features but is also more 
unstable.

If you are interested in which issues are left before releasing the 
stable 3.0.0-beta-1 version, please take a look at

https://issues.apache.org/jira/issues/?jql=project%20%3D%20COCOON3%20AND%20fixVersion%20%3D%20%223.0.0-beta-1%22%20AND%20status%20%3D%20Open%20ORDER%20BY%20priority%20DESC


If you are willing to help to speed up and improve this process, your 
contribution is highly appreciated.

Regards.
