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

Prerequisites

Fedora 4 requires Java 7 8 and Maven 3 (only for building the project). Check that you have them installed before proceeding:

Code Block

$ java -version
java version "1.78.0_12-ea73"
Java(TM) SE Runtime Environment (build 1.78.0_1273-ea-b08b02)
Java HotSpot(TM) 64-Bit Server VM (build 2425.073-b28b02, mixed mode)
 
$ mvn -version
Apache Maven 3.03.39 (r1075438bb52d8502b132ec0a5a3f4c09453c07478323dc5; 20112015-0211-28 0910T10:3141:0947-080006:00)
Maven home: /Users/usrkford1/sharePrograms/apache-maven-3.3.9
Java version: 1.78.0_12-ea73, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.78.0_1273.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.813.36", arch: "x86_64", family: "mac"

Building Fedora

...

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:

...

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

Code Block

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
