当我把log4j.xml去掉就没报错了
<?xml version="1.0" encoding="UTF-8" ?>

大哥那个不是没抱错，是出错了没地方报！！！！！

[shine333]

java.lang.UnsupportedClassVersionError: ajaxsample/SampleForm (Unsupported major.minor version 49.0)

这个是另外一个问题，你编译的时候，用JDK1.5，运行的时候用的是JDK1.4

[ntucz]

高手来来呀～～

[shine333]

stacktrace呢

根据最上面那个java.lang.reflect.InvocationTargetException

怀疑是<set-property property="definitions-config"，

而且肯定是它
<xxx>
<set-property property="yyy" value="zzz">
</xxx>

他的意思是在配置xxx对象初始化的时候，xxx.setYyy("zzz")显然Java世界中没有setDefinitions-config()
