public class DerbyNetworkServerDataStoreHelper extends DerbyDataStoreHelper
DerbyNetworkServerDataStoreHelper is a DataStoreHelper implementation
customized for the Derby database when running using the Derby NetworkServer framework.
When mapping a SQLException, the SQLException mappings from the
DerbyNetworkServerDataStoreHelper and
DerbyDataStoreHelper are searched first, and subsequently, if no match is
found, the SQLException mappings from the GenericDataStoreHelper
are searched.
If you have additional requirements on Derby you should consider subclassing this
implementation.
SQLException mappings specific to the DerbyNetworkServerDataStoreHelper
are the following:

DerbyNetworkServerDataStoreHelper constructor creates a new
DerbyNetworkServerDataStoreHelper based on the DataStoreHelper
properties provided. All implementations inheriting from a data store helper
must supply this same list of properties to their super class by invoking the

throws java.sql.SQLException
This method cleans up a statement before the statement is returned to the statement cache. This method is called only for statements that will be cached. It is called only if at least one of the following statement properties has changed,
DerbyDataStoreHelper resets all of the statement properties listed above
except for the cursorName property.
The following operations do not need to be included in the statement cleanup since they are automatically performed by WebSphere when caching statements,
