I have an APEX class that is used to send an email out each day at 7PM:
global class ReportBroadcaster implements Schedulable {
global ReportBroadcaster() {
}
global void execute(SchedulableContext sc) {
send();
}
global void send() {
PageReference page = new PageReference('/apex/nameofvfpage');
page.setRedirect(true);
Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
email.setSubject('Example Subject');
email.setHtmlBody(page.getContent().toString());
email.setToAddresses(new String[]{'[email protected]'});
Messaging.sendEmail(new Messaging.SingleEmailMessage[]{email});
}
}
When I execute the send() method via an instance of the ReportBroadcaster via anonymous APEX, it is delivered as expected. However, when I schedule the class, the email is delivered with a blank body. If I switch the email body to plain text, it delivers fine (but that doesn't work for me).
How do I make this work?
UPDATE:
You cannot call getContent() on PageReference instances from either scheduled APEX or @future methods (I'm not sure why that would be, but it is what it is). I think that the solution will be to create a web service that I'll call from the @future method. Seems incredibly hacky, but I'm not sure what else I could do.
This is how to send HTML emails from scheduled APEX:
Create a class that implements the Schedulable interface.
Have the execute() method call an @future method.
Have the @future method call a web service enabled method in the class that sends the email.
While this approach is roundabout, it works
