我正在开发一个Java应用程序，该应用程序连接到https://ut.eurodw.eu/（欧洲数据仓库的测试环境）中公开的SOAP服务。我正在使用最近重新格式化为Windows
8.1的开发计算机上工作。今天，我尝试通过我的程序通过SOAP向他们发送创建请求，并收到以下错误消息：

正如您通过单击我的上面的链接所看到的，这不是自签名证书，而是由GoDaddy公共CA发布的，并由我的Firefox浏览器识别。我的Java版本是1.7.0_60-b19。修改代码以允许不安全的SSL连接将是一个
坏主意 。

相反，我想确保eurodw的证书在信任库中。我该如何检查？以及如何导入新证书？

PS：我目前无法在部署最终应用程序的服务器上进行测试：我只能使用自己的Tomcat安装。
