1. Download and install Tomcat
2. Set the Java properties (e.g. /etc/default/tomcat7) mentioned in the following Application Configuration section

   for Tomcat
   • Many linux distributions put these settings a the file /etc/default/tomcat7, outside of the tomcat installation folder.
   • If your operating system does not have the file above, you can create a setenv.sh (or setenv.bat) script in the tomcat7/bin folder. Settings here will not be disturbed by upgrades to the tomcat package. For instance, the following bash line will add the fcrepo.home property to existing JAVA_OPTS.
   Copy the Fedora 4 WAR file into Tomcat's "webapps" directory (e.g. /var/lib/tomcat7/webapps)

   • A note on configuration: In the case where no Fedora 4 system properties have been set, Fedora tries to use the current-working-directory as the home of persisted data. If the Tomcat user does not have write access to the installation area (e.g. /var/lib/tomcat7), then Fedora 4 will not deploy. The simplest resolution is to set the system property: "fcrepo.home=<some-writable-directory>" in the Tomcat configuration file (e.g. /etc/default/tomcat7)

     Code BlocktitleExample fcrepo.home configuration
     

     JAVA_OPTS="${JAVA_OPTS} -Dfcrepo.home=/tmp/fcrepo4-home"

   • See the Java Properties section below for the properties you need.

3. Copy the Fedora 4 WAR file into Tomcat's "webapps" directory (e.g. /var/lib/tomcat7/webapps)

Deploying with Jetty 9

1. Download and install Jetty
2. Set the Java properties (e.g. /etc/default/jetty) mentioned in the following Application Configuration section

3. Copy the Fedora 4 WAR file into Jetty's "webapps" directory (e.g. /var/lib/jetty/webapps)

Java Properties

fcrepo.home=<some-writable-directory>

Sets the home for Fedora's persisted data. Without this setting Fedora tries to use the current-working-directory as the home of persisted data. If the Tomcat user does not have write access to the installation area (e.g. /var/lib/tomcat7), then Fedora 4 will not deploy. Set this system property to a directory writable by the tomcat process.
