Glassfish is an open-source application server for the Java EE platform. Glassfish is the reference implementation of Java EE and as such supports Enterprise JavaBeans, JPA, JavaServer Faces, JMS, RMI, JavaServer Pages and servlets. You must have a "glassfish" user and a "glassfish" group to run this script: groupadd -g 263 glassfish useradd -u 263 -g glassfish -d /var/lib/glassfish -s /bin/false glassfish The SlackBuild will use /var/lib/glassfish to store domain and node configuration files. The default domain1 will be installed to /var/lib but note that this will be overwritten on upgrade, so it is advised to install any applications into a differently-named domain. The rc.glassfish script will operate on the default domain unless another is specified on the command line.
