我的电脑中的 Web 服务程序出现错误，但相同的代码在其他电脑上运行正常。有什么解决办法吗？

我不确定您为此进行了多少搜索。

Java 文档说明了此错误背后的具体原因。

http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/AbstractMethodError.html

我认为您的 jar 不匹配...您在本地编译的 jar 和在不同的其他位置运行应用程序时使用的 jar。这是大多数此类问题的基本问题。您可以验证 jar 的版本...

我看了更多选项，但人们谈论不同版本的 jar ...请更好地查看您的 jar ..这可能会有所帮助...
