Log4j无法生成日志文件

Question

JBX＋tomcat
在JBX里直接运行Logtest.java文件，没有错误提示，正常结束，可是没有生成日志文件，请高手指点，代码如下：
Logtest.java：
package program.BusinessManger;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
public class Logtest {
  public static void main(String[] args){
    Log log = LogFactory.getLog("test");
    log.info("info");
    log.error("error");
  }
}
logtj.properties：
log4j.rootLogger=INFO,R
log4j.appender.R=org.apache.log4j.FileAppender
log4j.appender.R.File=C:\pro\log\allpro.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

Answer 1

你能保证log4j在启动时正确加载了吗？你把启动信息贴出来看看

Answer 3

使用log4j需要配置web.xml吗？？怎样配置？
哪位能留下qq或者msn，谢谢啊

Answer 4

在你的web.xml文件中加入
 <servlet>
    <servlet-name>log4j</servlet-name>
    <servlet-class>org.springframework.web.util.Log4jConfigServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

Answer 5

我用的是Spring中的log4j,你把servlet-class中的类换掉就行了

Answer 6

<!-- Log4j设置开始-->
  <servlet>
  <servlet-name>log4j-init</servlet-name> 
   <servlet-class>你的操作log4j的包</servlet-class>              
   
   <init-param>
   <param-name>log4j-config-file</param-name> 
     <param-value>/WEB-INF/classes/log4j.properties</param-value> 
   </init-param>
  
   <load-on-startup>1</load-on-startup>
  </servlet>
