I already put the log4jConfigLocation in web.xml, but I still get the following warning:

log4j:WARN No appenders could be found for logger ⤦
    ⤥ (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

What did I miss?

If that's the entire log4j.properties file it looks like you're never actually creating a logger. You need a line like:

log4j.rootLogger=debug,A1

You may get this error when your log4j.properties are not present in the classpath.

This means you have to move the log4j.properties into the src folder and set the output to the bin folder so that at run time log4j.properties will read from the bin folder and your error will be resolved easily.

You'll see this warning if log4j can't find a file "log4j.properties" or "log4j.xml" anywhere.

If still help, verify the name of archive, it must be exact "log4j.properties" or "log4j.xml" (case sensitive), and follow the hint by "Alain O'Dea". I was geting the same error, but after make these changes everthing works fine. just like a charm :-). hope this helps.
