Google App Engine 1.8.2 compatibility #4

Open khawkins98 opened 11 years ago

khawkins98 commented 11 years ago

I've just set up this API on GAE, but haven't been able to get anything but 500 errors.

I don't have much experience with Java, but a bit of Googling suggests that the init param setup in web.xml may be off ( example: http://stackoverflow.com/questions/7205761/jersey-tutorials-from-basics )

I suspect this is because I'm having to use GAE 1.8.2 and the API was last updated for 1.6.1

Or am I way wrong on this?

I also think it's because your using App Engine 1.8.2, but the web.xml looks like it is configured correctly. I would try updating jersey too and look for incompatibilities with App Engine and Jersey. Maybe you also find a simple working example with GAE 1.8.2 and the latest Jersey.
