NoSuchMethodError: com.google.inject.Scopes.isSingleton

[Michael]

I'm using guice 3.0 on servlet RPC in GAE.

when i am starting the server, i get the following error messages:

Apr 22, 2012 5:45:37 AM com.google.apphosting.utils.jetty.JettyLogger
warn
WARNING: Error starting handlers
java.lang.NoSuchMethodError: com.google.inject.Scopes.isSingleton(Lcom/

com.google.inject.servlet.ManagedFilterPipeline.initPipeline(ManagedFilterPipeline.java:

...

what is the possible cause of this error?

I'd be wary of possible classpath conflicts. Check your project's dependency structure to confirm you're only pulling in Guice from head.
