Hi Cote,

This post sounds really interesting but the link to your presentation seems to be dead. Would you mind reposting the ppt/pdf of your slides.

Cheers,
Kaushik

Sure, you need to open up logging.properties and uncomment out the FileHandler example that’s in there.

That file should be located at /jre/lib and just look around for “file” or “FileHandler.”

If not, search on google for something like “java file handler” and you should find some examples of configuring it.

I typically don’t use StringBuffers for log messages, I just use the argument’ed message with an Object array for arguments. My assumptions are that if you’re using an isLoggable, you’re not too concerned about the performance hit (if any) of what happens in the block. That is, your assumption is that you’d rather get the logging information than performance in that case.

Hey cote
Great ppt you got, I like the slide about the micro-optimizations it make me rethink my all logging.

I use isLoggable() and a Object[] in my code now I realized that I rather use Stringbuffer to build the msg …

did I got it right ? is it cheapter to use StringBuffer for the msg assuming there is a isLoggable() before the log ?

thanks
