log4j.appender.LOGFILE.File的路径默认就是Tomcat的bin想修改到其它目录而又不想用绝对路径的话，就使用相对路径。比如，你如果想设置为Tomcat目录下的LOG目录，就用
og4j.appender.LOGFILE.File=..\LOG\shitingguanai.log
og4j.appender.LOGFILE.File=..\LOG\shitingguanai.log
log4j.appender.LOGFILE.File=..\webapps\onlinehome\log\shitingguanai.log但是不行啊，同志，它还是打到bin目录下了，不过文件名叫作“..webappsonlinehomelogshitingguanai.log”我ft了！！！还有，log4j.properties的位置，有规定么？必须放到src下么？
谢谢指教！

文件夹下没有叫做logging的文件啊？！？！
要自己建一个么？？

No suitable driver
这两项都报了错
我怀疑可能是SQL SERVER的驱动没装好
但是在JSP里面又可以用请高手帮忙看看 谢谢
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=D:\Tomcat 5.0/logs/log4j.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n试试看吧
log4j.properties文件的位置怎么指定啊？
必须放在src目录下么？
<servlet>
<servlet-name>Init</servlet-name>
<servlet-class>
cn.dapei.common.config.InitServlet
</servlet-class>
<init-param>
<param-name>log4j</param-name>
<param-value>/WEB-INF/conf/log4j.properties</param-value>
<!-- 这个路径也可以自己定义-->
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>初始化Servlet的代码如下：
public class InitServlet extends javax.servlet.http.HttpServlet
implements javax.servlet.Servlet
{
private static Logger logger;
private final String LOG_FILE_PATH = "log4j.appender.file.File";
/**
*
*/
private static final long serialVersionUID = 1L; public void init() throws ServletException
{
try {
Properties pro = new Properties();
pro.load(new FileInputStream(getServletContext().getRealPath("/")
+ getInitParameter("log4j")));
String filePath = getServletContext().getRealPath("/")
+ pro.getProperty(LOG_FILE_PATH);
File file = new File(filePath);
if (!file.exists()) {
file.createNewFile();
}
pro.setProperty(LOG_FILE_PATH, filePath);
PropertyConfigurator.configure(pro);
logger = Logger.getLogger(InitServlet.class);
logger.info("加载日志配置成功.");
} catch (Exception e) {
throw new ServletException("加载Log4j配置文件失败.异常", e.getCause());
}
}
}
log4j.properties 配置如下：
