Why is there no output in the website.log file. Is there something wrong with log4j.properties
The contents of log4.properties are:
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=D:\\tomcat\\logs\\website.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.appender.R.MaxFileSize=200KB
log4j.appender.R.MaxBackupIndex=1
log4j.rootLogger=WARN, R
log4j.logger.website=DEBUG

throws ServletException, IOException

PrintWriter out = response.getWriter();
System.out.println("<html><body>Debug!</body></html>");
logger.debug("HomeServlet.doGet()");

You need:
log4j.category.HomeServlet = DEBUG, R
In your log4j.properties.
加载中,请稍侯......
