缺少jar包，通过运行你的项目，发现后台报错找不到类：
logback下面的类，下载最新的logback的包，地址为：

估计是red5.jar与slf4j-log4j12-1.6.6.jar中package和class重复造成的。
你先用压缩软件打开red5.jar，然后删除org.slf4j.impl包，试试看会不会报错。2013年4月25日 19:05

java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class org.slf4j.impl.StaticLoggerBinder)
Invocation of init method failed; nested exception is java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class org.slf4j.impl.StaticLoggerBinder)
即使用了不同版本的jdk编译的 造成不兼容
估计你的slf4j太新了
换成slf4j-api-1.5.6.jar试试
