Grails Mail service not working with guartz scheduler in war mode

Question

I send a mail at a specific time using quartz scheduler :

static triggers = {
   cron name: 'DashboardReporting', cronExpression:"0 0 11,20 * * ?"
}

Now inside execute I send the mail using grails async plugin which works perfectly under run-app mode:

emailNotificationService.sendDashboardReportEmail(emaiListing, [model:model,XYZmodel:XYZmodel])

Now this thing works perfectly when I do run-app for development purposes and sends mail from my local machine.

But when I run the same code using run-war I get this exception :

java.lang.NullPointerException

I have used the default quartz version provided by the async. Also a thing of note is I cound not directly inject the async mail service so I autowired it with :

 @Autowired
AsynchronousMailService asyncMailService

But again this thing is working fine with run-app and under other many usage of the service, only in war mode this error surfaces.

I also tried the normal mail plugin but had the same problem. Any suggestions guys ??

in your `Config.groovy` (or an external file if externalized config is used), is the `grails.serverURL` property set? — defectus, Aug 24 '15 at 13:58
I don't know how that should help in my context ??? But then no it's not set in external config or config.groovy. — haedes, Aug 24 '15 at 17:59
Because the NPE is caused by Grails unable to determine the server's URL. Just check the source code at `grails.plugin.mail.MailMessageContentRenderer$PageRenderRequestCreator.createInstance(MailMessageContentRenderer.groovy:198)` — defectus, Aug 25 '15 at 04:32
Great point out, thanks. But I believe such information must have been mentioned in the documentation. I mean I nearly ditched async mail service for an alternative. Thanks again. — haedes, Aug 25 '15 at 05:14

I know this question is already a bit older, but the answer provided does not work for me in grails 3.0.9. Specifically, it would require me to set a global serverUrl that overrides anything specified for any of the development/testing/production environments.

The below, added to BootStrap.groovy does the trick. It seems that the LinkGenerator initialization in grails is actually the culprit, rather than the mail plugin.

LinkGenerator grailsLinkGenerator = grailsApplication.mainContext.getBean("grailsLinkGenerator")
grailsLinkGenerator.configuredServerBaseURL = 
                    grailsLinkGenerator.configuredServerBaseURL ?:
                         grailsApplication.config.grails.serverUrl

I was having this problem with an integration test, but putting this line into the `setup()` method worked a treat. — Kara Potts, Aug 02 '16 at 14:36
I was ran into this issue when upgrading to 3.1.6 and this fixed my issue as well. Many thanks. — Taplar, Mar 02 '17 at 17:06
