z2-Environment

h1. Sample Groovy in Z2

h2. Prerequisites

All you need is a JDK 6 or JDK 7 distribution as described in [[Step_2_-_Install_and_run_in_5_minutes]].

h2. Setting up the sample

There is no further pre-requisite to running this sample, and you may proceed as described in [[How to run a sample]]. Here's the really fast version:

<pre><code class="ruby">

mkdir install

cd install 

git clone -b master http://git.z2-environment.net/z2-base.core

git clone -b master http://git.z2-environment.net/z2-samples.groovy

# on Linux / Mac OS:

cd z2-base.core/run/bin

./gui.sh

# on Windows:

cd z2-base.core\run\bin

gui.bat

</code></pre>

The first time you launch the sample will take a while. Watch the log output and keep an eye out for the following lines:

If you want to inspect the code using Eclipse, please create a workspace in install (i.e. @install/workspace@) and import the Git repositories and the following  projects into your workspace: _core_ from z2-base.core, _environemnt_ and _com.zfabrik.samples.groovy.web_ from z2-samples.groovy (see also [[Step_3_-_First_steps_with_Z2_on_Git|First steps]]).

The sample apps just print the HTTP request header - the "first":http://localhost:8080/plain-groovy-sample is using plain Groovy (see project @com.zfabrik.samples.groovy.web@) and the "second":http://localhost:8080/groovy-java-sample/ is using a mixture of Groovy and Java sources (see project @com.zfabrik.samples.groovy_and_java.web@). Note that while the former project is compiled using the plain Groovy compiler the latter is compiled using the Joint Groovy/Java Compiler.

Please refer to [[Groovy Add-on]] for more details and how-to use it for your own projects.
