Grails Service + quartz problem

Hi everyone!!!

I write an app in Grails but I have some problems with quartz.
I wanna fetch User from DB and after that fetch his servers as well.
If there will be any server I wanna check PING command on each one, but I get a message like this:

"
[quartzScheduler_Worker-1] ERROR listeners.ExceptionPrinterJobListener - Exception occurred in job: GRAILS_JOBS.<name>

This is my code.

def execute() {
pingService.checkPing()
}

def checkPing = {
User user = User.findByLogin(session.user.login) //get user
def hostsToPing = importFromDB()
if (!hostsToPing.isEmpty()) {
hostsToPing.each {host ->
doPing(host)
}
}
else {
//something else
}
}

def importFromDB = {
User user = User.findByLogin(session.user.login)
def hostsList = Host.findAllByUser(user)
hostsList
}

def doPing(Host host) {
println "InetAdress: " + InetAddress.getByName(host.hostAdress)
println "InetAdress is Rea: " + InetAddress.getLocalHost().isReachable(1000)
}


There isn't this problem when is something like this:

def doPing(Host host) {
println "InetAdress: " + InetAddress.getByName("www.google.com")
println "InetAdress is Reachable : " + InetAddress.getLocalHost().isReachable(1000)
}

Does anyone know whats wrong?

Thanks,
Kacu
