java - WSO2 Identity Server 5.10.0 和 Samples 4.2.0 继续出现 java.lang.ClassCastException : class org. opensaml.saml1.core.impl.ActionBuilder

Question

当我尝试 WSO2 Identity Server 的快速入门指南时。

场景 1 - 使用 SAML2 配置单点登录

生成http://localhost.com:8080/saml2-web-app-pickup-dispatch.com/。当我单击链接应用程序服务器崩溃并显示以下消息时:

HTTP ERROR 500
Problem accessing /saml2-web-app-pickup-dispatch.com/samlsso. Reason:

我在 Mac 和 Linux 平台上尝试过，但结果相同。是否有任何环境或配置问题使其工作？

Answer 1

这是一个已知问题[1]，并在随样本 v4.3.0 版本[2]一起发布的样本中得到修复。您应该能够从 [2] 下载新的 saml2-web-app-pickup-dispatch.com 示例。
