Using Oracle JDeveloper IDE and JDBC 4.0 to develop J2EE data-driven applications.

In J2SE 5.0, fi ve new implementations of RowSet—JdbcRowSet, CachedRowSet,WebRowSet, FilteredRowSet, and JoinRowSet—were introduced. The WebRowSet interface extends the RowSet interface and is the XML document representation of a

RowSet object. A WebRowSet object represents a set of fetched database table rows,

which may be modifi ed without being connected to the database.

Support for Oracle Web RowSet is a new feature in Oracle Database 10g driver.

Oracle Web RowSet precludes the requirement for a persistent connection with the

database. A connection is required only for retrieving data from the database with

a SELECT query and for updating data in the database after all the required row

operations on the retrieved data have been performed. Oracle Web RowSet is used

for queries and modifi cations on the data retrieved from the database. Oracle Web RowSet, as an XML document representation of a RowSet facilitates the transfer

of data.
