Appengine Sees User As Additional Parameter

I am using OAuth with my app-engine server. It's rather simple to do, simple add User as one of the parameters. But when I do I get the compile error Multiple entity parameters. t

Solution 1:

I have the feeling your User is not of type import com.google.appengine.api.users.User.

The documentation states that "there can only be a single entity parameter per method" (see https://cloud.google.com/appengine/docs/java/endpoints/parameter-and-return-types).

However "Any type except a parameter or injected type is considered an entity type" and com.google.appengine.api.users.User is of type "injected": so you should not have any problem normally, unless your User is not of this type.

Personaly I have methods like

public Customer insert(finalUseruser, Customer customer, ...

which work perfectly well
