I use the federated user options in GAE.

Sorry i'm not logged before send the issue.

[Christian Goudreau]

Thanks for reporting!

[Simon-Pierre Gingras]

Hi Patrice!

What version of GAE Studio are you using? What version of App Engine is your app using?

From what I can see, the current User version of App Engine has a ctor with 4 Strings params ( https://developers.google.com/appengine/docs/java/javadoc/com/google/appengine/api/users/User#User(java.lang.String, java.lang.String, java.lang.String, java.lang.String) )

[Patrice de Saint Steban]

Hi,

I use the last GAE Studio : 0.7 GAE version : 1.8.8

[Simon-Pierre Gingras]

We could try to see from which jar the User class is loaded.

Try this (just before your call to UserService.getCurrentUser():

ClassLoader classLoader = User.class.getClassLoader();

System.out.println(classLoader.getResource("com/google/appengine/api/users/User.class"));

This will print the jar from which the User class was loaded.

[Patrice de Saint Steban]

jar:file:/base/data/home/apps/s~egliseinfo-catholique-fr/gae-studio.373557782956034603/WEB-INF/lib/_ah_compiled_jsps-0000.jar!/com/google/appengine/api/users/User.class

[Simon-Pierre Gingras]

Can you inspect the contents of that jar and confirm that the User class does not have the constructor User(String, String, String, String) ?

[Patrice de Saint Steban]

The "_ah_compiled_jsps-0000.jar" is a jar compiled in appengine. I can't access to online appengine files.

[Simon-Pierre Gingras]

Okay, I thought you were experiencing this issue when running your app from your local machine. So if I'm understanding correctly, you're experiencing this issue with an app deployed on appspot, right?

[Patrice de Saint Steban]

Yes it's a deployed application and use the federated login option.

[Simon-Pierre Gingras]

OK, I'll build a sample, deploy it to app engine and see what's going on.

[Simon-Pierre Gingras]

I've deployed an app on appspot with GaeStudio installed in it, and I don't experience your problem. I don't get the NoSuchMethodError.

In my instance, it says that the User class is loaded from the appengine-api.jar :

jar:file:/base/java7_runtime/api/appengine-api.jar!/com/google/appengine/api/users/User.class

I'm wondering why your app would load the User class from _ah_compiled_jsps-0000.jar ...

[Patrice de Saint Steban]

Did your test application use federated login ? https://developers.google.com/appengine/articles/openid?hl=fr

[Simon-Pierre Gingras]

We used the Users service https://developers.google.com/appengine/docs/java/users/

Is it different from what you're using?

[Patrice de Saint Steban]

The Four parameters User class :

User(java.lang.String email, java.lang.String authDomain, java.lang.String userId, java.lang.String federatedIdentity)
Creates a new User with a federated identity.

Is used with the federated identity login, with this login option, you can login with open id provider. For this, you must implement the login page /_ah/login_required

[Simon-Pierre Gingras]

Okay I see, I'll update my sample project with this ASAP, and I'll see if the federated login breaks anything on my side.

[Former user]

@patricedesaintsteban @spgingras Does it work fine now?

[Simon-Pierre Gingras]

I haven't had the chance to test with federated login yet.

[Patrice de Saint Steban]

I haven't tested with the new version of GAEStudio yet

[Former user]

Please tell us when you will have had time to try it with 0.8.3 ;-)

Unable to replicate for the moment.
