Hello everyone, This is actually a repost since the same problem with turkish regional settings keeps haunting us.
We are having a - probably language settings-related - problem with an application that is using log4j to do its logging. The behavior is like that: With the default system language settings (Start > Settings > Control Panel > Regional Options > Language Settings for the System > Defaults...) set to "Western Europe and United States", the program works just fine. However, as soon as we switch the default to "Turkic", the program will only start to display an error message saying "Cannot initialize log file: null", and then exit. The OS is W2K Server, with JRE 1.4 + JSDK 1.4 + log4j 1.2RC1 The message's text saying that the log file cannot be initialized led to the guess that this could be a problem relating to Windows+log4j+Turkish triple. We *have* to set the system's default language setting to Turkish for other parts of integrated software to properly display Turkish characters. The log4j.dtd file and the application's logging configuration file are given below. Is there anything we can do to fix that? Any pointers deeply appreciated.

Specifically, 1. Log destinations 2. Log levels 3. Log format 4. Rollover (size based and time based) can all be configured. The default configuration illustrates various typical configuration options. The default configuration does the following 1. Log to the console (warn messages and higher) 2. Log in XML format to hwelog.xml (info messages and higher) 3. Log in HTML format to hwelog.html (info messages and higher) 4. Log asynchronously to hwelogasync.log (info messages and higher) 5. hwelog.xml will rollover after 100Kb 6. hwelog.html is truncated and overwritten on each run If maximum performance is an important factor, increase the log levels to warn or fatal, and use fewer log destinations. You can log to a variety of other destinations also simply by modifying the configuration file. These include 1. JMS queue (JMSAppender) 2. Database via JDBC (JDBCAppender) 3.
