Okay a bit more details now that I have done this process by hand for
DB2 and Oracle.
In each case I copied:
- JDBCDataStoreFactory.createDataSource(params, dialect))
And inlined the following method to make it one complete bundle.
- getJDBCUrl( params )
So option (a) with this in mind:
- public BasicDataSource
OracleNGDataStoreFactory.createDataSource( params )
- I would not need the dialect as it is just used to control if
prepared statements are pooled
- the Existing createDataSoruce(params,dialect) method can remain
protected; and make use of the above BasicDataSource
However I am not sure how the BasicDataSource / DBCPDataSource is
managed. I think for my purpose I could work with just the
BasicDataSource?

I am wading into the udig code changing over to the jdbc-ng
implementations. And I have run into an interesting need; some of the
wizard pages want to make use of a Connection in order to ask a few
questions as they walk users through the process of setting up a
datastore.
The difficulty is the only code I can get a good connection from is
private in JDBCDataStoreFactory.createDataSource( params, dialect).
The dialect is only used here to figure out if
setPoolPreparedStatements should be set to true. Then the whole mess
is wrapped up in a DBCPDataSource before being returned.
For today i am going to have to just cut and paste code; but I
should ask if:
a) this code can be factored out or otherwise made visible
b) are we going to allow applications to choose between DBCP and C3PO?
This is a repeat of Andrea's question from last week.
