my app begun in 2002, it accesses database using cmt, later we found ejb is tedious, and hard to add new function, so we adopt hibernate, spring. Now there are [three ways] to access database( cmt, hibernate, spring(HibernateDaoSupport)), each uses different datasource, every datasource has its own connection pool.
the databse is oracle 9i.
[three ways] writes different tables, but can read all tables. Now there is no table that can be written by two of the [three ways].
But now I hope spring can write all tables, is there any problem ?
I think it will have problem , but I have no confirmative infomation. Any idea is appreciated, thanks
