JPA(OpenJPA)を使用しています。私の中に次のエントリがありますpersistence.xml:
<property name="openjpa.RuntimeUnenhancedClasses" value="supported"/>
Serviceofferingにリストされているクラスもありますpersistence.xml。JPA 関連のコードを実行しようとすると、次の例外が発生します。何が問題になる可能性がありますか?
No metadata was found for type "class com.XYZ.cloud.bss.client.db.data.Serviceoffering". Ensure that the class is enhanced (if necessary), that the class has appropriate metadata, and that if you list your persistent classes, the class is included in your list.
