【问题描述】：
java.lang.NoClassDefFoundError: org/apache/commons/chain/config/ConfigParser
我在 Weblogic 9 上部署了一个 Struts 1.x Web 应用程序。请参阅此特定错误行，构建路径中似乎缺少 commons-chain-x.x.jar。我尝试了几个不同版本的commons-chain.jar（1.1 和 1.2），但没有帮助。我也在谷歌上搜索了几个小时，找不到任何解决方案。这里的实际问题是什么？缺少.jar 是否真的导致servlet 正确初始化？
p.s. 我知道...Struts 早已过时，不再广泛使用，但出于某些原因我不得不这样做。如有任何帮助，我们将不胜感激。

“Struts 1.x”不是一个有用的诊断；在不让我们看图像的情况下保持精确。 IIRC S 1.3.9 在 Chains 1.1 上。
lib目录中的文件并不重要，重要的是实际部署的内容。
