Hi guys,
In JDO datastore,can any one tellme how i could add more fields to my data store.That is, i already have a data store having 6 fields and as of latest,i have found a requirement that my software requires to have two more fields,how can i add these fields to the existing datastore retaining
all the previous records.I am using a File Object Store (FOStore)implementation to store my data

Does Sun reference implementation given any Schema mapping tool.

Waiting for replys

The JDO RI is suitable for learning the JDO technology but should not be used in real applications. Althought it's a good implementation, you don't have offical support from Sun. At least, you should contact Sun for a contract support.

Instead, you should use one of the many JDO open source implementations supporting relational databases.
I agree. Here's the link:
