Question

我正在尝试在DocuSign API工作流程（http://iodocs.docusign.com/APIWalkthrough/requestSignatureFromDocument）中运行示例程序，以发送一个简单的文档来请求签名。我将我的值替换为程序中的选定变量（integratorKey到docContentType），并且能够在上周成功发送请求。但是，当我运行示例程序时，特别是在第65行，调用conn.getResponseCode（）方法时，我“无法找到有效的证书路径到请求的目标”错误。完整堆栈跟踪显示在下面：

我在DocuSign DevZone档案中查找了这个错误，并找到了这个引用：http://community.docusign.com/t5/DocuSign-API-Integration-Java-READ-ONLY/ValidatorException-while-sending-document-to-Docusign-demo/m-p/6771/highlight/true。答案指向另外两个链接，基本上需要下载一个名为InstallCert.java的Java程序并运行它以获取一些证书信息然后安装证书。它应该在本地安装证书，然后当你第二次运行程序时它应该识别证书。

那对我不起作用！

如何使示例RequestSignatureDocument.java程序运行？

http-colon中第65行附近的行 - // iodocs.docusign.com/APIWalkthrough/requestSignatureFromDocument如下所示： `

// obtain baseUrl and accountId values from response body 
response = getResponseBody(conn);
baseURL = parseXMLBody(response, "baseUrl");

`

我无法肯定地说这是我的问题的答案，因为我没有收到来自DocuSign的任何反馈，但经过两整天的搜索文档，博客，StackOverflow等，我以为我终于有了一个有效的解决方我按照How can I use certificate authentication with HttpsURLConnection?上发布的大多数步骤进行了操作，并且能够连接并发送文档以供签名。

感觉很好！但后来我尝试了上面帖子顶部引用的原始java程序，现在它工作正常，就像上周那样（但不是本周的前几天）。因此，我在SSL上所做的工作，将证书导入我的密钥库等都没有任何相关性或有意义。

我想我很难想到这一点，但我必须假设DocuSign上的某个人上周改变了一些东西，然后今天又改回来了。

如果我在这个假设上错了，而且DocuSign的某个人可以让我直截了当，那真的很棒。迟到总比不到好。但是直到某些事情发生变化，我的问题似乎已经解决了＃34;。
