我想在Eclipse中使用Java创建Web服务 我正在使用Tomcat 8.5和Axis2-1.7。 首先，我创建了一个Web服务项目（服务器端）。然后，我创建了一个客户端项目以调用Web服务。
问题是，在创建客户端项目后，当我想将Web服务客户端添加到项目中（定义wsdl）时，出现此错误：
为WSDL生成代码期间发生异常：java.lang.LinkageError：org / apache / xml / dtm / ref / dom2dtm / DOM2DTMdefaultNamespaceDeclarationNode
几天以来，我一直在搜索有关此异常的信息，但没有找到任何答案。如果有人帮助我，我将不胜感激。
以下是我得到的所有例外情况：
