[ http://jira.qos.ch/browse/LBCLASSIC-299?page=com.atlassian.jira.plugin.syste... ] Ceki Gulcu commented on LBCLASSIC-299: -------------------------------------- Bryan, could you please provide a test case reproducing this issue?

MDC properties sometimes were empty (DBAppender) ------------------------------------------------

Key: LBCLASSIC-299 URL: http://jira.qos.ch/browse/LBCLASSIC-299 Project: logback-classic Issue Type: Bug Affects Versions: 0.9.30 Environment: win xp, jdk1.6.0_22, weblogic 10.3.4 Reporter: Bryan Lin Assignee: Logback dev list

I put the userId and userName into MDC while login, but sometimes it was not written to DB. After debug I found that while the actual type of "event.getMDCPropertyMap()" is Collections$SynchronizedMap, MDC was not empty; but when it return HashMap, then MDC is empty.

[ http://jira.qos.ch/browse/LBCLASSIC-299?page=com.atlassian.jira.plugin.syste... ] Ralph Goers commented on LBCLASSIC-299: --------------------------------------- You said you added the userid and user name into the MDC during login. You need to add them to the MDC on every request and clear the MDC at the end of the request. If you aren't doing that then problems such as what you are experiencing would occur. What we typically do is to create a "SessionContext" Map that contains all the data that is valid for the session and then copy it to the MDC on every request. Since your AJAX call is on a different request, and thus probably a different thread, than the login you would need to follow this pattern.
