I have doubt using jpa. I defined the datanucleus connection for MYSQL as follows.
datanucleus.ConnectionDriverName=com.mysql.jdbc.Driver
datanucleus.ConnectionURL=jdbc:mysql://localhost/myDB
datanucleus.ConnectionUserName=...
datanucleus.ConnectionPassword=..
My constraint is if I want to connect to google app engine datastore(ie Big table) via jpa
how to give the above connection for bigtable.
You don’t need to configure any settings in order to persist to Bigtable using JPA – just run it inside the App Engine environment, and it ought to work fine.
