Eclipse 不是RegistryBuilder为一个项目添加的Tapestry AppModule，可以很好地用于另一个项目

我正在使用EclipseMars、Tomcat7、Java8、Sysdeo DevLoader，并随后配置了tomcat插件

我有两个几乎相同的Tapestry项目。一个应用程序运行良好，另一个应用程序无法提供任何页面，抛出：

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.

然后，我看到Tapestry的“你好”，我的另一个项目（

admin

）出现了：

……但实际上是沉默。我看不出这两个应用程序有什么不同，会导致一个正常工作，另一个失败。我应该看哪里？

DevLoader类路径错误。修好了，一切都修好了

DevLoader类路径不包括路径

/myapp/target/classes

——这就是我的应用程序的AppModule所在的位置（

/myapp/target/classes/com/mydomain/myapp/services/AppModule.class

）。这可以在

Project->Properties->Tomcat

中修复，并选中正确路径的复选框。在项目的

WEB-INF

旁边名为

#webclasspath

的文件中也可以看到错误的配置，该文件列出了完整的路径（相对路径显示在配置页面中）。修复设置后，启动Tomcat并自动更新

#webclasspath
