Thanks Adrian,
Although I may not have explained the question properly.
I am not running unit tests. Here's what happens:
Guice starts up, it runs module configuration.
While it is running module configuration, it comes across the
following:
bind(Query.class).annotatedWith(Names.named("PersonQuery"))
.toProvider(new Provider<Query>(){
@Override
public Query get() {
return new Query(Person.kind);
}
});
The problem is that the call: new Query(..) is dependent on
ApiProxy.Environment. BUT, because the Module is not a servlet, the
thread that runs it does not have an instance of ApiProxy.Environment
sent. Hence the error:
1) Error in custom provider, java.lang.NullPointerException: No API
environment is registered for this thread.
while locating com.google.appengine.api.datastore.Query annotated
with @com.google.inject.name.Named(value=PersonQuery)
What I need to do is inside the module, inside public void configure
(), something to the tune of ApiProxy.setEnvironmentForCurrentThread
(<some environment>) . This is production code, I don't know where to
get <some environment> from.
