java - 错误 - 代码在 NetBeans 中有效，但在 .jar 命令行中无效

Question

我有一个相当奇怪的问题。下面的代码就完成了。我的项目只有这个类。在netbeans中我可以正常运行它，没有任何问题。但是，当我通过 java -jar "C:\Users\lucas\Documents\NetBeansProjects\WS_Apisul\dist\WS.jar" 运行时代码没有按照您想要的方式运行，特别是当您输入 soapResponse = soapConnection.call(msg,url) 时.

返回的错误如下:

错误出现在代码的开头。

RequestSoap = lerPasta();

您的错误表明发送的请求不正确，事实确实如此。当文件夹为空时，会发生错误，即向服务器发送 null，并呈现所示的错误。

你可以解决这个问题

   RequestSoap = lerPasta();
    If (requestSoap == null) {
        RequestSoap = lerPasta();
    }
    Else {
        // Your code
    }
