""" Finding commits by SHA-1 hash on Github. This is a simple
brute-force search for a specific usecase: you assume that the commit is
within all repos forked from a certain root repo within the past n days.
This may result in many calls to the GitHub API, which in turn may result
in GitHub's rate limiter kicking in and forcing you to take a break. You
have been warned.
Built with Python 3.4 and github3.py 0.9.4.

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)
