How Can I Test DailyRollingFileAppender?

Hi all, I tried to find an answer for my question in the archives, but I couldn't find it. Please forgive me if this is duplicate post. I'm trying to use DailyRollingFileAppender in the Spring IOC container (J2SE). My OS is Windows. I've tried to test if DailyRollingFileAppender creates an

Re: Setting logging levels

You attach your logging level to your logger. You can specify your log4j configuration properties in file by using PropertyConfigurator.configure(String configFilename). You can also configure log4j by using some of the other methods of PropertyConfigurator. For example, you can create a java

Log Multi-Line Messages

I'm logging the a message from a server that may span several lines. For example: 220 Connected to server. 220 Connection will close if idle for more than 5 minutes. When log4j prints this to my log file, the output looks like this: 2008-04-30 08:59:01 [MyThread] DEBUG MyClass.myMethod(): 220

FileAppender Truncates Stack Trace

Hello, I'm using FileAppender to log to a log file. When an exception gets caught and printed, the stack trace is truncated as it usually is by default: Caused by: com.sybase.jdbc3.jdbc.SybSQLException: Attempt to insert NULL value into column 'id', table 'table'; column does not allow nulls.

Same Configuration File, Different Hierarchies, and Different Log Files

Re: An odd configuration need...

You don't have to manage your disk space from within log4j. To conserve hard-drive space, you can use classes in the java.util.zip package to zip up your log files. You can schedule a nightly batch job that kicks off a Java class that uses java.util.zip. The book "Java i/O" by O'Reilly gives

This approach will work, but you have to make sure that your application runs without throwing exceptions. I've done this with my client-side Sybase EAServer classes (the jar files for these classes add up to more than 10 MB), and found that just compiling is not a guarantee that the code will

Re: Possible/practical to make "debug" use one set of appenders, but "error" use a different set?

Hi David. It's in Ceki's book, Chapter 3. You can set the threshold of an appender different from the threshold of its logger. Since you can have more than one appender for a logger, it follows that one logger can have appenders that are set to different thresholds. At 11:21 AM 04/22/2004

You could create a class boolean variable that is set once by isDebugEnabled(). Then you could say: private boolean debug = logger.isDebugEnabled(); In you method code you could say: if (debug) cat.debug(myObject.showState()); This would make it so that you only call isDebugEnabled() once in
