无法在WSo2身份服务器上运行示例sso示例travelocity.com

我试图在我的tomcat web服务器上运行示例travelocity.com，并使用WSO2身份服务器作为身份提供者（IdP） . 我在我的本地tomcat上部署了travelocity.com.war并使用 http://localhost:8080/travelocity.com 访问了该应用程序，它被重定向到WSo2身份服务器到 https://localhost:9443/samlsso ，并给出了错误

"SAML 2.0 based Single Sign-On
    Error when processing the authentication request!
    Please try login again."

我在本地tomcat中的catalina.log文件中的错误是

没有对使用样本战生成的travelocity.properties文件进行任何更改，并且是默认的

WSo2身份服务器上的服务提供商设置是默认的，并且正如文章中所要求的那样

我有两个问题（1）使用SAMl SSO运行和访问示例travelocity.com应用程序时抛出错误的原因是什么（2）如果我必须在我已经运行的java应用程序中使用WSO2身份服务器实现SAMl SSO（没有单个）登录），在我的应用程序结束时必须进行哪些更改 . 因为在这里我们可以看到有travelocity.properties文件和一些编码（大约4个文件： - ForwardingServlet.java，SampleAttributesRequestor.java，SampleContextEventListener.java，SSOAgentSampleFilter.java）将第一个请求重定向到身份提供者https://localhost:9443/samlsso我会有什么变化在我的申请结束时做 .
