log4j不能输出类名和错误行，我的错误在哪里

ouyingyufei

log4j.properties文件：
log4j.rootLogger=info,CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern= %4p [%t] ( %F : %L ) - %m%n - [%c]-[%L]

Sample.java测试类：
package log4j;

import org.apache.log4j.FileAppender;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
//import org.apache.log4j.SimpleLayout;
import org.apache.log4j.PatternLayout;

public class Sample {
static Logger logger = Logger.getLogger(Sample.class);

public static void main(String args[]) {
//SimpleLayout layout = new SimpleLayout();
PatternLayout layout = new PatternLayout("%4p [%t] (%F:%L) - %m%n");
FileAppender appender = null;
try {
//把输出端调置到output.txt
appender = new FileAppender(layout, "output.txt", false);
} catch (Exception e) {
}
logger.addAppender(appender); //添加输出端
logger.setLevel((Level) Level.DEBUG);//覆盖了配置文件中的info级别
logger.debug("Here is DEBUG message ");
logger.info("Here is INFO message");
logger.warn("Here is WARN message");
logger.error("Here is ERROR message");
logger.fatal("Here is FATAL message");
}
}
ant的build.xml文件：
<?xml version="1.0"?>
<project default="run" basedir=".">
<property name="src" value="src" />
<property name="compile" value="classes" />
<property name="myclasspath" value="${compile}" />

<!-- Include own classes -->

<fileset dir="${lib.dir}">
<include name="**/*.jar" />
</fileset>
</path>

<target name="prepare">

<!-- Copy property files and O/R mappings -->

这个类名输出？

经过JavaWorld论坛的xyz20003指导，找到了问题的源头：
<javac srcdir="${basedir}" destdir="${compile}" debug="yes">

ant在使用javac编译源程序的时候，debug默认是关闭的。打开就好了。
