Hi,
Actually I switched back to the previous approach (integration method 1) and
adding shutdown hook in my main class.
...
Runtime.getRuntime ( ).addShutdownHook ( new Thread ( )
{
public void run ( )
{
if ( logService.isInfoEnabled ( ) )
{
logService.info ( "shutting down the print service"
);
}
try
{
printService.stop();
}
catch ( ApplicationException e )
{
if ( logService.isErrorEnabled ( ) )
{
logService.error ( "error stopping print
service", null, null, e );
}
}
}
} );
...
Everything is working fine now.
