log4j的部分配置：
log4j.appender.DATABASE.sql
INSERT INTO T_LOG4J(stamp,thread,infolevel,class,messages) VALUES ('%d{yyyy-MM-dd HH:mm:ss}', '%t', '%p', '%l', '%m')
------解决方案--------------------------------------------------------
问题就是没有jdbc驱动。
把jdbc的jar文件添加到classpath中，如果是web项目，将其放到WEB-INF/lib目录下
#呵呵，第一次看到用log4j把log存数据里的。
------解决方案--------------------------------------------------------
代码发上来看看
------解决方案--------------------------------------------------------
把
log4j.rootLogger=DEBUG,CONSOLE,DATABASE,A1
中的DATABASE去掉就可以了
变成
log4j.rootLogger=DEBUG,CONSOLE,A1
------解决方案--------------------------------------------------------
真是没完没了的问题，你那个问题已经解决了，就应该结贴了，这是一个新问题
