Re: dynamic variables/parameters
I don't anymore. I am pretty new to log4j and started a new project where I
figured it would be nice to be able to have data logged to different tables
based on who the client was. Not the best way to do it, but I was wondering
if there was a way to do this. Now thinking about it, probably not what
log4j is used for. To do this I would probably have to reload the log4j
config file for each thread (and not sure if that would cause threading
issues).
I did figure out how to load parameters into the log4j thanks to all the
help from everyone. I will be setting up java's System properties, and then
reloading the config file once.
Thanks for all the help

I seem to get warning whenever log4j configure file is loaded. I looked at my config file and can see no syntax problems. Can somebody point me in the right direction???

Re: dynamic variables/parameters
I need to use the xml version. Also, please read my reply to the previous response I got. I think it applies. Again, I need a way to change the values for each new client connection (servlet thread). I don't think reloading the properties for each thread is the way to go (although this seems to be the only solution that might work at this point - if I don't use the xml config). thanks for the help, any other ideas? osubb Maarten Bosteels wrote: > > When you use a log4j.properties file instead of log4j.xml > you can use > http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PropertyConfigurator.html#configure(java.util.Properties) > > 1) load the log4j.properties file in a Properties object > 2) add all custom properties to the Properties object > 3) call PropertyConfigurator.configure(props) > > I have no idea if something similar can be done with the DOMConfigurator. > You could search the ml archive, this question has come up more than once. > > Maarten > > On Thu, Feb 14, 2008 at 12:23 AM, osubb <[EMAIL PROTECTED]> wrote: > >> >> I am pretty new to log4j and have a question that should be easy.

Re: dynamic variables/parameters
I don't believe this will work. The system properties are set once the
Servlet is started. I will have different parameters for each new
connection (thread) of the servlet. I need a way to alter the values for
each thread. I thought of using MDC, but that only worked when using the
"ConversionPatter" or using the "sql" param for JDBCAppender.
Is there any way to pass in values to log4j for each client connection
(Servlet thread)??
thanks,

dynamic variables/parameters
I am pretty new to log4j and have a question that should be easy. I am using log4j in a web (java servlets) environment. 1) How do I pass in variables? I have an app that uses the JDBCAppender and would like to pass in the connection values. Is there an easy way to do this? These values could be different for each client that access the Servlet(s). Is there a pattern for this type of scenario? At this point, I have to hardcode the URL, user, and password values in the log4j.xml file. I tried using MDC, but this seems to work in the "ConversionPattern" param for log files and the "sql" param name for the JDBCAppender. It does not work for the "URL", "user", and "password" param values (does not change to MDC value).
