按照此处所述安装 Juddi 服务器后http://thoughtsasaservice.wordpress.com/tag/juddi/我可以在这里进入主界面：
http://localhost:8181/juddiv3/
但是当我单击（查看服务列表）时，我发现404错误
HTTP Status 404 - /juddiv3/services
type: Status report
message: /juddiv3/services
description: The requested resource (/juddiv3/services) is not available.
此外，当我进入
http://localhost:8181/pluto/portal/jUDDI
我发现了这个错误：
Error rendering portlet.
org.apache.pluto.PortletContainerException: Unable to obtain the servlet context for the portlet app context path [/uddi-portlets]. Make sure that the portlet app has been deployed, and that cross context support is enabled for the portal app.

请指教。谢谢
错误消息显示并非所有 jUDDI 的 Web 应用程序都已成功部署。检查catalina.out，因为在您发布之前可能会有更多问题。
请记住，jUDDI对其底层软件（如JDK，MySQL和Tomcat）非常敏感。
确保您拥有与 http://thoughtsasaservice.wordpress.com/2011/07/22/how-to-install-juddi-on-tomcat/中所述完全相同的版本
我建议从Apache jUDDI网站下载预打包的版本。最新版本（3.1.5）可以工作，但是我认为组件不起作用。
或者，您可以从主干中获取源代码并构建具有全新用户界面的 3.2。
编辑：如果启动页面有效，而服务列表不起作用，则可能表明您正在使用不同的 soap 堆栈（Apache CXF 除外）。如果这是真的，那么服务列表可能会在不同的网址上。
