I’d like my Grails web-app to send an e-mail for each exception that reaches the end-user.

Basically I’m looking for a elegant way to achieve something equivalent to:

  try {       // ... all logic/db-access/etc required to render the page is executed here ...   }   catch (Exception e) {       sendmail('exception@example.com', 'An exception was thrown while processing a http-request', e.toString);   }

  1. Turns out this exact question was answered on the Grails mailing list a couple of days ago.

    The solution is to add the following to the log4j-section of Config.groovy:

    log4j {     ...     appender.mail='org.apache.log4j.net.SMTPAppender'     appender.'mail.To'='email@example.com'     appender.'mail.From'='email@example.com'     appender.'mail.SMTPHost'='localhost'     appender.'mail.BufferSize'=4096     appender.'mail.Subject'='App Error'     appender.'mail.layout'='org.apache.log4j.PatternLayout'     appender.'mail.layout.ConversionPattern'='[%r] %c{2} %m%n'     rootLogger='error,stdout,mail'     ...     // rootLogger='error,stdout' (old rootLogger) }

    Plus adding sun-javamail.jar and activation.jar to the lib/-folder.
