Hi All,
In my application I am trying to send e-mails to our customers when some "event occurs" for eg. like when we receive a payment or a new customer sign in...
I am successfully able to capture to those events and I am trying to send the mail and here comes the problem I am using JMS to have all this sending mail functionality in the back ground..
So when a new customer signs up I am saving its details in DB and an event is generated. Now to send mail I need to access the information of customer (or any other domain object which is relevant) using the code below
protected Map getObjectsMap(Map domainMap){
Map objectsMap = [:]
domainMap.each{key,value->
def dc = grailsApplication.domainClasses.find{it.getFullName().equals(key)}
// println "dc=$dc; dump=${dc.dump()}" // org.codehaus.groovy.grails.commons.DefaultGrailsDomainClass
def obj = dc.clazz.get(value)
//println "value=$value return=$obj; dc.clazz=$dc.clazz; dump=${dc.clazz.dump()}"
if(!obj) {
log.error "Could not find object of type $key with id=$value"
//def session = sessionFactory.currentSession
//println "session=$session; dump=${session?.dump()}"
}
String objectName = key.substring(key.lastIndexOf(".")+1)
objectName = objectName.charAt(0).toLowerCase().toString() + objectName.substring(1)
objectsMap.put(objectName, obj)
}
return objectsMap
}
The problem is that this code runs on my local machine (which is slower) but not on production server.
I think what is happening is that this background thing is getting executed earlier than object getting saved to DB. (I do have .save(flush:true) when I save the instance). Here is the stack trace which I get
biz.MailService Could not find object of type customer.Customer with id=5
biz.MailService Could not find object of type customer.Customer with id=5
biz.MailService Could not find object of type payment.Payment with id=7
biz.MailService Could not find object of type payment.Payment with id=7
