Here is an example to set JAVA_HOME:
export JAVA_HOME=<JDK/JRE_home>
To see the available command options type:
<geronimo_home>/bin/geronimo.sh
or
<geronimo_home>/bin/geronimo.bat
The command will display help text instructing you as to how to start and stop the Geronimo server.
If you prefer to start the server without a script file you can simply type:
java -jar <geronimo_home>/bin/server.jar
Once the server has started, you can access the Geronimo Administration Console at *http://localhost:8080/console/* . The default user name is "system" and the default password is "manager".
