future method error handling

Hi

How to send an exception email if the Future method fails, i have tried this in catch block but it throw mixed DML exception.

Inside the future method within the try block am trying to create a User record, if any error occurs in User record creation then the DML exception is catched in the catch block, in that case i need to send an email to system admin about the error in user account creation.

please let me know your ideas to implement this

Thanks

Hi Dinesh Sivalingam,

Below is the sample code for the same.
  
try{
     update account;
} catch (DMLException e){
     ApexPages.addMessages(e);

     Messaging.SingleEmailMessage mail=new Messaging.SingleEmailMessage();
     String[] toAddresses = new String[] {'developer@acme.com'};
     mail.setToAddresses(toAddresses);
     mail.setReplyTo('developer@acme.com');
     mail.setSenderDisplayName('Apex error message');
     mail.setSubject('Error from Org : ' + UserInfo.getOrganizationName());
     mail.setPlainTextBody(e.getMessage());
     Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
}
