Hi All, Please advise me whether the following is possible, and how to go about implementing it in Logback. I have a web app, with servlets for the web pages, as well as soap web services. Additionally, I have some background threads that do all sorts of interesting things. The servlets, web services and background threads all use the same data model classes which are backed by an orm data access layer, which uses JDBC to get data from a DB. I want all logging that happens while handling a servlet request to go to one log file, all logging that happens while handling a soap web service call to go to another log file, and all logging that happens in a background thread to go to another log file. Also, I want to log all the data model, orm and JDBC layer information to separate log files at debug and up level. For example, imaging the following list of log events (in this order): Logger Level Expected log files x.soap info soap.log x.model info soap.log,model.log x.orm debug orm.log x.orm info soap.log,model.log,orm.log x.jdbc debug jdbc.log x.jdbc info soap.log,model.log,orm.log,jdbc.log x.soap calls x.model, which calls x.orm, which calls x.jdbc. Similar traces for x.servlet, x.helperthread etc. I cant use Logger name to decide which appenders log, but what can I use? How can I achieve this? I would appreciate any pointers. Thanks, Jesse
