安全问题吧，改 安全策略文件

上面列的错误信息不是很全：

log4j:ERROR No appenders could be found for category (com.pow2.webgui.WidgetFact
ory).
log4j:ERROR Please initialize the log4j system properly.

是tomcat的问题，我下的一个开源软件，是用tomcat3.X部署的，
我用了4.x后，就出了上面的问题！我发mail问了软件的作者，他给我说
3.x和4.x的web.xml的配置文件有所不同，我按他提供的解决方案，还是不行，
他说要等一段时间，调试好后，再给我答复！
各位老大，有没有碰见过这种情况！

系统Policy文件的缺省位置为：
{java.home}/lib/security/java.policy (Solaris)
{java.home}\lib\security\java.policy (Windows)

把上面的打开然后添加
permission java.io.FilePermission “E:/tools/jakarta-tomcat-4.1.24/webapps/web/WEB-INF/classes", “read";

保存 重启 试试看

其实为什么一定要放那？？？？

你把JDK重装一下，如果用的是JBuilder就把Jbuilder重装一下，我以前也碰到没有对文件访问权限的问题

其实配置本身的问题应该不大，我自己的配置是这样的：
log4j.rootCategory=info, stdout, R
#log4j.rootCategory=debug, stdout, R
log4j.category.org.dbforms=warn, stdout
log4j.category.com.pow2=debug, stdout, R
#log4j.category.com.pow2.acl=debug, stdout, R

# stdout Appender
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n


# RollingFile Appender
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File = E:/tools/jakarta-tomcat-4.1.24/webapps/web/WEB-INF/classes/log.txt

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
#log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c%m%n
关键是没有权限读写log文件
（楼上的那位仁兄，麻烦你以后copy东西时，也顺手打几个回车，要对大家的眼睛负责呀！）

用这个试试看

第一步 配置log4j配置文件
=========================
# Set root logger level to DEBUG and its only appender to A1
#log4j中有五级logger
#FATAL0
#ERROR3
#WARN4
#INFO6
#DEBUG7
log4j.rootLogger=DEBUG, A1
# A1 is set to be a ConsoleAppender.
#log4j中Appender有几层
#ConsoleAppender输出到控制台
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
#输出格式 具体查看log4j javadoc org.apache.log4j.PatternLayout
#d 时间 ....
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

第二步:写启动的Servlet


import org.apache.log4j.PropertyConfigurator ;import org.apache.log4j.Logger ;import org.apache.log4j.Level ;public class InitServlet extends HttpServlet {public void init() { ServletContext sct = getServletContext(); String prefix = sct.getRealPath("/"); //log4j 配置文件存放目录 System.out.println("[....Log4j]: The Root Path: " + prefix); System.out.println("[....Log4j]: InitServlet init start..."); String file = getInitParameter("log4j"); //log4j 配置文件 if (file != null) { PropertyConfigurator.configure(prefix + file); //根据配置初始化log4j } System.out.println("[....Log4j]: InitServlet Init Sucess...");}public void doGet(HttpServletRequest req, HttpServletResponse res) {}public void doPost(HttpServletRequest req, HttpServletResponse res) {}}

我是用的这个配置文件 你看看把

#### Use two appenders, one to log to console, another to log to a file
log4j.rootCategory=debug, stdout, R

# Print only messages of priority WARN or higher for your category
log4j.category.your.category.name=WARN

#### First appender writes to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

#### Second appender writes to a file
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log

# Control the maximum log file size
log4j.appender.R.MaxFileSize=100KB
# Archive log files (one backup file here)
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
