The installation processes described above should enable Poseidon to run properly on your system. However, some adjustments can be made by using environment variables in order to make Poseidon fit even better in your personal environment. Please refer to the instructions of your operating system to see how environment variables can be set and persisted.
JAVA_HOME
- determines the path to the
version of Java Poseidon should use for itself and the Java
related tasks that can be done with it. Please remember that the
code generation feature will need a complete SDK (i.e. a full
install of Java that contains the compiler). If you don't want to
generate and compile code from Poseidon, a runtime environment
(JRE) is sufficient. Setting this variable is absolutely necessary
for starting Poseidon using the batch scripts (poseidon.sh or
poseidon.bat). The installer will search for the installed Java
versions and let you choose which version to use for Poseidon.
Once the installer has completed, this decision can be changed by
a re-installation of Poseidon only.
POSEIDONxx_HOME
- determines the path to
the folder where Poseidon can store user related settings and the
log files. (Please note that xx stands for the edition you are
using, i.e. CE for Community Edition, SE for Standard Edition and
so on.) By default, Poseidon uses the home folder of the user.
Please refer to the instructions of your operating system to see
what folder is used as your home folder on your system. Some
operating systems use rather strange settings for the home folder
in networking environments, so it might be necessary to use a
different folder than the default one. Defining this environment
variable lets you choose a different folder. On Windows using the
Standard Edition, you may want to set POSEIDONSE_HOME to
C:/Documents and Settings/yourname
.
