NoClassDefFoundError,有没有终极解决方案啊?

[twht]

情况是:需要运行原来编译通过的CLASS,换了台电脑,把需要的CLASS也放在了文件夹里,CLASSPATH也设置了路径
但是运行时还是出现这样的错误?
为什么呢?


D:\c\com\apex\util\writer>java MainFrame

java com.apex.util.license.writer.MainFrame

MainFrame.class要放在com/apex/util/license/writer/目录下。

[紫炎圣骑]

到D:\c\目录下：执行命令：java com.apex.util.license.writer.MainFrame

是不是CLASSPATH忘记加上这个----------->.

NoClassDefFoundError 是类加载失败。这个没有终极解决办法。类是找到的，就是加载出问题，出问题的可能很多。
