javax.jdo.JDOUserException: Persistent class "Class blar.blar.blar does not seem to have been enhanced. You may want to rerun the enhancer and check for errors in the output." has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class.
blar.blar.blar 明明就是早八百年前都在讀寫的資料持久化類別,怎麼可能不見?去 Google 一下,原來別人也發生過,而且解法也令人意想不到:
- 編輯 Project > properties > Google > App Engine > ORM
- 移除 src/
- 新增 src/blar/blar/*.java
