我在ServletExec上使用XMLBean时遇到了这个问题。我该如何解决？

Answer 1

从应用程序的类路径中删除xercesImpl-jar并重新部署它。如果由于删除特定jar而引起任何其他问题，请尝试这样做。然后不要删除jar.Just提取jar并从org.apache.xerces.parsers.AbstractSAXParser中删除xercesImpl-jar类文件，这会导致冲突并转换剩余的类文件进入jar并将其加载到classpath.It将帮助您解决链接错误。

Answer 2

您似乎正在部署xerces-parser以及您的应用程序，尽管它已经是服务器的一部分 - 并且服务器似乎扼杀了它。尝试从部署中删除xercesImpl-jar，例如如果maven将其范围设置为provided。
