I'm using Eclipse Mars, Tomcat7, Java8, Sysdeo DevLoader and I followed a Tynamo tutorial to configure the tomcat plugin.
I have two almost identical Tapestry projects. One app works fine the other won't serve any pages, throwing:
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.

The problem seems to stem from my AppModule.addRealms not being called in the problem app before the security manager tries to get the Subject. In fact it seems that one of the apps enjoys the 'Tapestry treatment' and the other does not. Here's the one that works:

Then I see the nice "hello" from Tapestry and my other project (admin) comes up:

I expected to see something like this after my admin.xml descriptor is deployed:
[INFO] ioc.RegistryBuilder Adding module definition for class com.myotherdomain.admin.services.AppModule
[INFO] TapestryModule.ComponentClassResolver Available pages (16):
...but instead there is silence. I can't see anything different in the two apps that would cause one to work and the other to fail. Where should I look?
The DevLoader Classpath was wrong. Fixing that fixed everything.
The DevLoader Classpath did not include the path /myapp/target/classes -- and that's where my app's AppModule was (/myapp/target/classes/com/mydomain/myapp/services/AppModule.class to be exact). This can be fixed in Project -> Properties -> Tomcat and checking the checkbox for the right path. The wrong configuration can also be seen in a file next to the project's WEB-INF called .#webclasspath which spells out the complete path (the relative path is shown in the config page). After fixing the setup, start Tomcat and .#webclasspath should be automatically updated.
