Well java.lang.System is whitelisted, so won't java.lang.System.out.println(...) work?

+1: Yes, according to the docs writing to stdout will be captured and logged at the INFO level. Likewise, writing to stderr will be logged at the WARN level. – David Underhill Jun 26 '10 at 14:19
Is there somewhere in particular it needs to go? It wasn't working in the doPost() function I had. – user124384 Mar 21 '16 at 01:32

Try using the java.util.logging.Logger class. See the docs for examples and more information.

It does not print on console. – Manjoor Jun 26 '10 at 14:00
Strange, what level did you try to log at? INFO level and higher should appear. Writing to standard out is supposed to be logged by GAE to the logs at the INFO level in the Java runtime. – David Underhill Jun 26 '10 at 14:18

if you configure it properly, you can get the Logger to output to the console. – Peter Recore Jun 26 '10 at 14:52
