java - log4j in a multithread environment. One Appender per Thread or one Logger per Thread or...? -

-

in multithreaded environment (web service provider) need create log entries in database per request (normally per thread). approach use this?

  • same logger threads , create appender per thread. @ end of request/thread close/remove appender.

  • a logger per thread (different class name per thread). @ end of request/thread somehow release specific logger

  • other?

from apache log4j faq:

yes, log4j thread-safe. log4j components designed used in heavily multithreaded systems.

as marko topolnik comments, ignore multithreading when planning logging statements, , let log4j take care of it.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
