    <p>We have a requirement in the application that the log file created shoud have a different name every time it executes (based on functionality + the current thread). I have seen the questions already posted in SO and tried to use the same method, but it is not working.</p> <p>All the log statements are getting logged in "xyz.log" (specified in the log4j.properties). Only "org.apache.log4j.PatternLayout" gets logged in abc.log (specified in the program). Any pointers to solve this will be very helpful. </p> <p><strong>log4j.properties</strong></p> <pre><code>log4j.rootLogger=DEBUG, MyLogger log4j.appender.MyLogger=org.apache.log4j.FileAppender log4j.appender.MyLogger.layout=org.apache.log4j.PatternLayout log4j.appender.MyLogger = org.apache.log4j.DailyRollingFileAppender log4j.additivity = false log4j.appender.MyLogger.File=xyz.log log4j.appender.MyLogger.MaxFileSize = 5MB log4j.appender.MyLogger.MaxBackupIndex = 20 # Pattern to output the caller's file name and line number. log4j.appender.MyLogger.layout.ConversionPattern=%d %5p [%t](%c:%L) - %m%n </code></pre> <p><strong>Java code</strong></p> <pre><code> logger = Logger.getLogger(MyLoggerUtil.class); Layout layout = new PatternLayout("org.apache.log4j.PatternLayout"); logger.removeAllAppenders(); FileAppender appender = null; try { appender = new FileAppender(layout, "abc.log", false); } catch (IOException e) { e.printStackTrace(); } logger.addAppender(appender); logger.setLevel((Level) Level.DEBUG); logger.debug("This is a debug test"); </code></pre>

    1. COThe constructor of `PatternLayout` expects a pattern not a class name. Sth. like the conversion pattern you used in the properties file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
