Building GlassFish on FreeBSD, too...........

Glassfish on FreeBSD

Yes, you could build the Open Source GlassFish on FreeBSD platform, too.

Since I have build GlassFish on two version of FreeBSD (6.0 and 6.1) from scratch; therefore, I think it would like good to share my experience on how to do it. Following is just a quick note on how one could build Glassfish on FreeBSD.
FreeBSD or other BSD will be just like another UNIX (POSIX) platform (Solaris, Linux, Mac) that could build and run GlassFish.

How to set "jvm option" or "system properties" in GlassFish or Sun Java System Application Server?

  You could either use asadmin command "create-jvm-option" or "create-system-properties" .

For example:

    i) If you want to set environment variables "ORACLE_HOME=/export/oracle" for the appserver instance to refer. In appserver, it would use "create-system-properties" command..

        Sample syntax for the command to add system property:
        /opt/SUNWappserver/appserver/bin/asadmin create-system-properties --user admin --passwordfile /tmp/adminpasswordfile --host localhost --port 4849 --target your_server ORACLE_HOME=/export/oracle

    ii) If you want to set JVM option.

        Sample syntax for the command to add jvm option:
        /opt/SUNWappserver/appserver/bin/asadmin create-jvm-options --user admin --passwordfile /tmp/adminpasswordfile --host localhost --port 4849 --target your-server \\\\-Dcom.sun.jndi.ldap.connect.pool.protocol="plain ssl"

a) create-jvm-option sets the variable for the jvm.   User would use this command to change the heap size, profiler and other VM related options see:

b) create-system-properties sets the <system-property> element in the domain.xml.  The variable is also set in the vm but at a lower priority.   User can also set this to overwrite default values set in the config or domain level.

If you need more detail on the variable on Glassfish or Application Server please see the following URL:  for a more detailed descriptions between jvm-option and system-properties.
