Hi All, 
How can i write log message in a file (/WEB-INF/logs) in GWT? it seems log4j is not supported but then i wrote a servlet (to be loaded when application starts to load my custom ""(from /WEB-INF/classes/ file and load it into java.util.LogManager but i get below error 

java.lang.NoClassDefFoundErrorjava.util.logging.LogManager is a restricted class. Please see the Google App Engine developer's guide for more details. 

my point here is to write log messages into a file under /WEB-INF/logs. 

If you're using AppEngine (and intend in deploying to AppEngine), then I think you'll have to use java.util.logging and the logs will go to the AppEngine console (I never used AppEngine so this is just a guess).

As you say you want to write to WEB-INF/logs, I'll take it that you don't want to deploy to AppEngine, in which case I think you mistakenly enabled AppEngine for your project in Eclipse? You can disable it from the project's properties.

Note that writing to WEB-INF/logs won't work in some servlet containers if you use a WAR file (some servers won't unpack your WAR file, or will unpack them in a temporary folder).
