Chapter 3.
JOnAS Configuration
This chapter describes how to configure JOnAS.
3.1. JOnAS Configuration Rules
As described in Chapter 2 Getting Started with JOnAS , JOnAS is pre-configured and ready to use
directly with
RMI/JRMP
for remote access, if visibility to classes other than those contained in the
JOnAS distribution in
$JONAS_ROOT/lib
is not required.
To use
RMI/IIOP
for remote access or to work with additional Java classes (for example, JDBC driver
classes), you must perform additional configuration tasks, such as setting a specific port number for
the registry.
The JOnAS distribution contains a number of configuration files in
$JONAS_ROOT/conf
directory.
These files can be edited to change the default configuration. However, it is recommended that the
configuration files needed by a specific application running on JOnAS be placed in a separate location.
This is done by using an additional environment variable called
JONAS_BASE
.
3.1.1. JONAS_BASE Environment Variable
Warning
JOnAS configuration files are read from the
$JONAS_BASE/conf
directory. If
JONAS_BASE
is not de-
fined, it is automatically initialized to
$JONAS_ROOT
.
There are two ways to use the
JONAS_BASE
environment variable:
1. Perform the following actions:
a. Create a new directory and initialize
JONAS_BASE
with the path to this directory.
b. Create the following sub-directories in
$JONAS_BASE
:
• conf
•
ejbjars
• apps
•
webapps
• rars
• logs
c. Copy the configuration files located in
$JONAS_ROOT/conf
into
$JONAS_BASE/conf
.
Then, modify the configuration files according to the requirements of your application, as
explained in the following sections.
2. Perform the following actions:
•
Initialize
$JONAS_BASE
with a path.
•
Change to the
$JONAS_ROOT
directory and enter:
ant create_jonasbase
