-- creating and using a Cassandra counter column in CQL
-- NOTE: this is CQL 2.0 syntax, it will NOT work with CQL 3 (for syntax reasons and because CQL 3.0 drops the very notion of dynamic columns...sigh)

CREATE KEYSPACE test WITH strategy_class = 'SimpleStrategy'
  AND strategy_options:replication_factor = '1';

USE test;

CREATE TABLE stats (KEY text PRIMARY KEY) WITH comparator=text AND default_validation=counter;

Servlets with CDI

• get latest Jetty 9.1 archive and extract somewhere (I'll assume the Jetty root is called "jetty")
• in jetty/lib, create a folder called "weld" and download the weld-servlet and weld-servlet-core JARs into it. For injection in listeners to work, version should be 2.2.0.Beta1 or later.
• in jetty/modules, create a weld.mod as in this gist
• in jetty/start.ini, add a single line containing "--module=weld" to initialise Weld

In most cases, that should be it and you can deploy any compliant CDI application, even without a web.xml. In some cases though you may need to add the old-fashioned filter entry to the web.xml. See also: https://github.com/weld/core/pull/465

Servlets with CDI and JAX-RS 2.0 (using Jersey)
