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

Prerequisites

Fedora requires Java 8 and Maven 3 (only for building the project). Check that you have them installed before proceeding:

Code Block
$ java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
 
$ mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T10:41:47-06:00)
Maven home: /Users/kford1/Programs/apache-maven-3.3.9
Java version: 1.8.0_73, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.13.6", arch: "x86_64", family: "mac"

Building Fedora

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

Clone the latest code from Github:

Code Block
$ 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 may take some time and bandwidth to download all the development dependencies):

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

Running the Fedora 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)

Code Block
$ cd fcrepo-webapp
$ MAVEN_OPTS="-Xmx512m" mvn jetty:run
[...]

There's a nice, friendly HTML interface waiting for you at  http://localhost:8080/rest/  (the default username and password is fedoraAdmin)

REST API Examples
