When I use toplink,I put "<property name="toplink.ddl-generation" value="create-tables"/>" into persistence.xml.Then i don't need create table in database by my hand.I just write a java bean and r/w it from database.Ifit's not existed of the table,toplink will create it.
I can't find it in openjpa.If you have this function,please tell me.I think it's very useful function. Thank you!
