我的action方法里需要掉用类A的方法B 就出现了上面的异常错误 导入的包什么的都是正确的
在同一个action内 建立一个main函数 在main函数内同样调用这个方法却可以正常执行 请问下这是什么原因啊
请大家帮忙看看问题出在哪了 我log4j的代码如下
log4j.rootLogger=info, A1,B1
#打印到文件
log4j.appender.A1=org.apache.log4j.RollingFileAppender
log4j.appender.A1.File=log/SMLog.log
log4j.appender.A1.MaxFileSize=1000000KB
log4j.appender.A1.MaxBackupIndex=1
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%5p [%t] (%F:%L) -%d %m%n
#打印到控制台
log4j.appender.B1=org.apache.log4j.ConsoleAppender
log4j.appender.B1.layout=org.apache.log4j.PatternLayout
#log4j.appender.B1.layout.ConversionPattern=%-4r %-5p [%t] %37c %3x - %m%n
#log4j.appender.B1.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.B1.layout.ConversionPattern=%m%n
[解决办法]
No Log4j.properties found
没找到log4j配置，查看一下位置是不是放错了，
ps:你的action继承DispatchAction？
