本文介绍了NoClassDefFoundError的例外，当我使用Omnifaces ::阿贾克斯:: update（）方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

当我尝试运行Omnifaces库有关Ajax :: update（）方法将样品code，我得到了NoClassDefFoundError的例外;

When I try to run the sample code of Omnifaces library about Ajax::update() method, i get the NoClassDefFoundError exception;

我想，它涉及有关客户端ID或组件的标识，但我不知道如何避免此异常。

I suppose that it concerns about the client-ids or ids of components, but I do not know how to avoid this exception.

任何帮助将是AP preciated。

Any help would be appreciated.

感谢。

推荐答案

而不是采取在$ C $一个深沉的样子c您发布，NoClassDefFound异常通常通过连接问题造成的，无关的实际工作code写的。请确保您在需要的类路径中的一切包括

while not taking a deep look in the code you posted, NoClassDefFound exceptions are usually caused by linking problems and are unrelated to actuall code written. make sure you include in your classpath everything needed

这篇关于NoClassDefFoundError的例外，当我使用Omnifaces ::阿贾克斯:: update（）方法的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
