RE: SMTP log4j question
Howdy, You need to access the SMTPAppender object and call its methods to dynamically change the properties like the subject line. How are you configuring log4j? If you know the name of the SMTPAppender, e.g. EmailAppender this is pretty easy. In your class, you would do something like: Logger rootLogger = Logger.getRootLogger(); SMTPAppender email = (SMTPAppender) rootLogger.getAppender(EmailAppender); email.setSubject(New subject line); email.setTo([EMAIL PROTECTED]); email.activateOptions(); If you don't know the name of the appender, or don't want to hard-code it, you can still do this. Use Logger.getAllAppenders() to get all the appenders, then iterate through them checking for appender instanceof SMTPAppender. A couple of notes since you mentioned you're new to this: 1. By default the SMTP appender will send out ERROR and higher messages only. If you want it to send INFO or lower, you will need to change its Threshold. Alternatively, you can write a custom TriggeringEventEvaluator for the appender to use. 2. If you have a small number of possible subject lines and to addresses, consider creating one SMTP appender for each combination.

RE: SMTP log4j question
Howdy, Don't use the same name for a logger as you do for an appender: log4j is fine with it but it's confusing to humans. In the code I sent you I assumed your SMTP appender is attached to the root logger. In the configuration below, it's not, so the SMTPsetup variable is null. You can either attach it to the root logger and use my code, or use SMTPAppender SMTPsetup = (SMTPAppender) Logger.getLogger(SMTP).getAppender(SMTP); Yoav Shapira Millennium ChemInformatics -Original Message- From: Miller,Catherine [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 18, 2003 9:02 AM To: 'Log4J Users List' Subject: RE: SMTP log4j question Here is a snippet of my properties file.
