GAE java.lang.IllegalStateException: Must call one of set*BlobStorage() first

Question

I am trying to upload a file in GAE using the Blobstore API. I am getting the following exception when running the GAE server locally (dev mode):

WARNING: /_         


        

Answer 1

I am not using Maven, just Eclipse and the GAE plugins. I also didn't see any test.jar files in my classpath. I just deleted the Run Configuration in Eclipse and restarted and it worked. No idea what went wrong, but this fixed the issue for me while running in dev/local mode.
