Thank you for your informative post on GAE/J logging.

>On the real appengine, you cannot run JUnit tests
Just as FYI, with CloudCover, you may be able to run existing Unit test suites in actual production GAE/J server (although I could not make it work when I briefly tried about a year ago while thinking of options of how to test the Wave robot.) No sign of CloudCover developments for about a year does also not encourage much to try it though. ;-)

Why don't you use the java.util.logging implementation of slf4j (slf4j-jdk14-1.6.1.jar)?

Binding with a logging framework at deployment time

Thanks a lot for your informative description. It was probably a huge timesaver for me.

With that I was able to configure the JUL through the logging file java-util-logging.properties.
If you put in the following lines in the properties file:

java.util.logging.ConsoleHandler.level=FINE
java.util.logging.ConsoleHandler.formatter=aa.test.server.MyFormatter

and provide the following class on the server:

public class MyFormatter extends SimpleFormatter {
private SimpleDateFormat s;
private StringBuffer sb;
public MyFormatter(){
super();
s=new SimpleDateFormat("MM-dd-yyyy HH:mm:ss");
}
public String format(LogRecord r){
sb = new StringBuffer(s.format(new Date(r.getMillis())));sb.append(":");
sb.append(r.getLevel().toString());sb.append(" ");
sb.append(r.getSourceClassName());sb.append(".");
sb.append(r.getSourceMethodName());sb.append("():");
sb.append(r.getMessage());sb.append("\n");
return sb.toString();
}

You can programmatically change the log format.
This makes me really happy as I do not need to use log4j or slf4j anymore.

And in real appengine I simply remove the properties file.

thanks a lot for the description! now it works... ...
