Re: Log4j logging for Orion EJBs

[Eddie]

Hellu,   I use log4j very well with Orion... I have no problem logging from the EJB into a file.. The point is that you are not allowed to write directly from a file/read from a file in a EJB. So, what you do is, tell the Log4j Category class to log a entry. The Category class than writes, through the apropiate appenders in for example a file So the EJB doesn't write in the file directly. I use a RollingFile and SMTP appender and it works great.   PS: 1: the same is true for reading for example file properties: call another class that returns our properties, stored in files. 2: Use on log.properties file for all your J2EE applications, otherwise you sure get into problems, as log4j uses static variables/methods and it is hard, and unnecessary, to use one log4j-core.jar for every J2EE appication. It works even quite well to have one log4j engine/ config file..   Good luck, Ed     ----- Original Message ----- From: Joe Sackett To: [EMAIL PROTECTED] Sent: Sunday, September 16, 2001 10:26 PM Subject: Log4j logging for Orion EJBs Hello, I am considering using log4j as our logging mechanism for EJBs deployed in Orion 1.5.2.  I appreciate all of the up-front logging model provided by the Category and Priority intersections. My concern is that some Appenders may not work well within an EJB container.  I considered and ruled-out the console, remote server, Unix Syslog daemon, JMS listener, NT EventLog and e-mail types for various reasons specific to our application.  I would like the log4j output to go to a log file, but know this may violate the EJB spec. Could someone please make a suggestion on how log4j can write to a file from an Orion-hosted EJB or refer me to a related archived posting or discussion thread.
