Question

我正在使用相对未知的API。（ScrumWorks Pro）我用它将数据导出到SQL数据库中。我的问题是我已经将我的eclipse项目从一台计算机移动到另一台计算机，它停止了工作。它继续在旧计算机上正常运行，但我收到以下错误

Exception in thread "main" javax.xml.ws.WebServiceException: Failed to access the WSDL at: http://XXXXXXX:8080/scrumworks-api/api2/scrumworks?wsdl. It failed with:

看起来它正在运行时无法连接到主机。但它在另一台计算机上使用完全相同的凭据完全正常。

Answer 1

神奇的词语：Server returned HTTP response code: 503。答案将在您的服务器日志中。

来自https://tools.ietf.org/html/rfc2616#section-10.5.4：

The server is currently unable to handle the request due to a 
temporary overloading or maintenance of the server.

Answer 2

确保网址

http://XXXXXXXXXX:8080/scrumworks-api/api2/scrumworks?wsdl

是可访问的，如果无法访问8080端口，请检查该计算机中的防火墙设置（允许该8080端口可访问）

Answer 3

问题是较新的计算机安装了较新版本的Java，这破坏了API的部分内容。

在另一台计算机上完全相同的代码上运行时错误
