如何在通过Talend Open Studio访问的Web服务中配置http basic auth？

Question

例如，我有一个关于Web服务，只有方法getVersion返回应用程序版本。

我可以通过SoapUI轻松调用它：

但是，通过Talend中的Job访问它似乎是不可能的。

我尝试过最简单的一个：

已配置身份验证，admin / ****为用户/密码。

但是，每次我运行我的作业时，都会以下列错误结束

所以看来我的服务器不接受提供的身份验证。真是奇怪，因为调试我的领域会发现一些经过身份验证的调用。但是，似乎最后一次通话也是未经授权的。为什么？

修改

我通过在Glassfish中启用HTTP日志记录进行了一些测试，然后为每个工具执行一次测试。

使用soapui，我得到了

"127.0.0.1" "NULL-AUTH-USER" "07/Nov/2013:10:45:51 +0100" "POST /digital-express-soap/AboutService HTTP/1.1" 401 1069 
"127.0.0.1" "admin" "07/Nov/2013:10:45:51 +0100" "POST /digital-express-soap/AboutService HTTP/1.1" 200 247 

使用Talend Open Studio for Data Integration 5.3.1，我得到了

"127.0.0.1" "NULL-AUTH-USER" "07/Nov/2013:11:03:27 +0100" "POST /digital-express-soap/AboutService HTTP/1.1" 401 1069 
"127.0.0.1" "admin" "07/Nov/2013:11:03:27 +0100" "POST /digital-express-soap/AboutService HTTP/1.1" 200 247 

据我所知，完全相同。因此，对我的服务器进行查询的顺序是相同的，但客户端解释它的方式会发生变化。

因此，我的问题现在可以更改为“为什么Talend无法正确解释当服务器401返回时soapui可以，考虑两者都基于类似的开源Web服务堆栈？”
