Chapter 2. Getting Started with JOnAS 19
2.2.2.4. Building the eb Example
The simplest way to compile this example is to go to the
$JONAS_ROOT/examples/src/eb
directory ($JONAS_ROOT/examples/src/eb/) and use the
compile.sh
shell script
($JONAS_ROOT/examples/src/eb/compile.sh).
If the
Ant 1.5 build tool is installed on your machine, you can build the JOnAS examples by using
the
build.xml
files located in the
$JONAS_ROOT/examples
or
$JONAS_ROOT/examples/src
directories. To do this, use the
build.sh
shell script.
2.2.2.5. Running the eb Example
Here, again, two processes are involved:
•
The JOnAS server in which beans will be loaded
•
The Java client that creates instances of beans and calls business methods on it.
To run this example:
1. Run the JOnAS server to make beans available to clients:
service jonas start
jonas admin -a eb.jar
The following messages are displayed on the standard output:
The JOnAS Server ’jonas’ version-number is ready and running on rmi
message-header : AccountExpl available
message-header : AccountImpl available
2. Run the Java clients in another terminal emulator window:
jclient eb.ClientAccount AccountImplHome
jclient eb.ClientAccount AccountExplHome
The example
eb
has run successfully if the following output displays:
Getting a UserTransaction object from JNDI
Connecting to the AccountHome
Getting the list of existing accounts in database
