This document will walk you through getting the code, building the webapp, and exercising the REST API. 

Prerequisites

Fedora 4 requires Java 7 and Maven 3 (only for building the project). Check that you have them installed before proceeding:

$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
 
$ mvn -version
Apache Maven 3.0.3 (r1075438; 2011-02-28 09:31:09-0800)
Maven home: /usr/share/maven
Java version: 1.7.0_12-ea, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.7.0_12.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.8.3", arch: "x86_64", family: "mac"

Building Fedora 4

You can download pre-compiled binaries and run Fedora 4 in an existing Tomcat or Jetty instance. or pre-packaged Jetty instances, or build Fedora 4 from source (it's not difficult or too time consuming).

Clone the latest code from Github:

$ git clone https://github.com/fcrepo4/fcrepo4.git
Cloning into 'fc4'...
remote: Counting objects: 40152, done.
remote: Compressing objects: 100% (12759/12759), done.
Receiving objects:  14% (5622/40152), 3.68 MiB | 912 KiB/s  
[...]
 
$ cd fcrepo4

And build the project (the first time you build Fedora 4 may take some time and bandwidth to download all the development dependencies):

$ MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m" mvn clean install

Running the Fedora 4 webapp

The webapp can be run from a bundled instance of jetty. The application will listen on port 8080 by default.
If you would like to run the webapp on a different port, you can add the "jetty.port" option in your maven command (e.g. mvn -Djetty.port=8181 jetty:run)

$ cd fcrepo-webapp
$ MAVEN_OPTS="-Xmx512m" mvn jetty:run
