Re: RequestScoped and background threads

[Stephan Classen]

The request scope uses internally a thread local. So when you run stuff in a 
background thread you are not in a request as guice sees it. You need to call 
the same method as the mentioned filter does inorder to begin and end a request.

RequestScoped and background threads

[Arun Thirupathi]

In one of our projects we are binding an implementation in RequestScope. 
But when this is run from a background thread, it fails with the exception 
below. 

Error in custom provider, com.google.inject.OutOfScopeException: Cannot 
access scoped object.
Either we are not currently inside an HTTP Servlet request, or you may have 
forgotten to apply
com.google.inject.servlet.GuiceFilter as a servlet filter for this request.

Can I bind different implementations based on the scope ? I want to provide 
one implementation in RequestScope and other implementation in another 
scope.

Is there a way to configure Guice to ignore these errors silently. 

Currently I am thinking of the naive way of, try/catch all the usage of 
this object, which is far too many and there are new interactions with this 
object.

I run my project inside Google App Engine, if that matters.

Thanks,
Arun.
