Hello,
I've written my first session bean that is
automatically called by the timer service
of JBoss. My question is:
How can I do to start the session bean
initialization just after the deployment of my
ear?
For now: I have to call a specific url (jsp) that
call a method of my session bean runAtlas():
<code-extract>
public void runAtlas()
throws RemoteException
{
if( listener == null )
{
System.out.println( "### Launch the timer ###" );
// obtain the MBeanServer
lServer =
MBeanServer)MBeanServerFactory.findMBeanServer( null ).get( 0 );
try
{
Set lBeans = lServer.queryMBeans( new
bjectName( "DefaultDomain",
"service",
"timer"
),
null
);
if( !lBeans.isEmpty() )
{
// Should be the first and only element
System.out.println( "### Timer service present! ###" +
Timer.ONE_MINUTE );
lTimer = (ObjectInstance)lBeans.iterator().next();
listener = new Listener();
lServer.addNotificationListener( lTimer.getObjectName(),
listener,
null, // No filter
null // No object
handback necessary
);
Date lNext = new Date( new Date().getTime() + 5000);
//Date lNext = new Date( new Date().getTime() +
Timer.ONE_HOUR );
atlasTimerRef = (Integer)lServer.invoke(
lTimer.getObjectName(),
"addNotification",
new Object[] { "IDoNotKnowWhatTypeIs",
"I call you with this timer once",
null, // No user object
lNext, // In one minute from now
new Long( 10000 )
// , new Long( 10 )
},
new String[]
{
"".getClass().getName(),
"".getClass().getName(),
"java.lang.Object",
Date.class.getName(),
Long.TYPE.getName()
// , Long.TYPE.getName()
}
);
}
else
System.out.println( "### Could not launch the timer,
service DefaultDomain:timer not installed! ###" );
}
catch( MalformedObjectNameException mone )
{
System.out.println( mone.getMessage() );
}
catch( InstanceNotFoundException infe )
{
System.out.println( infe.getMessage() );
}
catch( MBeanException mbe )
{
System.out.println( mbe.getMessage() );
}
catch( ReflectionException re )
{
System.out.println( re.getMessage() );
}
}
}
</code-extract>
TIA
Loic
