我使用Eclipse Mars，Tomcat7，Java8，Sysdeo DevLoader和我遵循a Tynamo tutorial来配置tomcat插件。RegistryBuilder没有为一个项目添加Tapestry AppModule，可以正常工作
我有两个几乎相同的Tapestry项目。一个应用程序运行良好，但对方不会服务于任何页面，投掷：
SEVERE: Servlet.service() for servlet [default] in context with path [/admin] threw exception
java.lang.RuntimeException: Exception constructing service 'WebSecurityManager': Error invoking constructor public org.tynamo.security.services.TapestryRealmSecurityManager(org.tynamo.security.Authenticator,org.apache.shiro.mgt.SubjectFactory,org.apache.shiro.mgt.RememberMeManager,java.util.Collection): Realms collection argument cannot be empty.

这个问题似乎从干我AppModule.addRealms没有被调用的应用程序的问题之前，安全管理器尝试获取Subject。事实上，其中一个应用程序似乎喜欢'挂毯治疗'，而另一个则没有。下面是工作的一个：

然后我看到了漂亮的“你好”由Tapestry和我的其他项目（admin）出现：

我希望看到这样的事情我admin.xml后描述符被部署为：

[INFO] TapestryModule.ComponentClassResolver Available pages (16):
......但相反有沉默。在两个应用程序中我看不到任何不同的东西，这会导致一个人工作，另一个人失败。我应该在哪里看？
