http://developer.java.sun.com/developer/earlyAccess/crs/ JDBCTM RowSet This Early Access release includes three implementations of the JDBCTM RowSet interface. The RowSet interface provides a serializable, scrollable container for tabular data that may or may not be connected to its data source via a JDBC technology-enabled driver. A disconnected RowSet object, such as a CachedRowSet object or a WebRowSet object, can be thought of as a set of rows that are being cached outside of a data source. Because they are lightweight and serializable, disconnected rowsets can be passed between different components of a distributed application, such as Enterprise JavaBeansTM components. This is one of the most important uses for a RowSet object. The data in a RowSet object may be updated and then resynchronized with the underlying tabular data source. The RowSet Early Access Technology Release contains the rowset jar file, preliminary documentation and code examples. Additional documentation on RowSets is contained in the JDBC 2.0 Optional Package API specification. The Java Developer Connection(SM) also provides on-line access to the RowSet tutorial chapter of the new JavaTM series JDBC book. Early Access Release 4 addresses the following areas:fixed problem inserting rows with non-nullable columns re-ordered code in writer to allow multiple changes to a single row to be propogated back to a data source reader/writer now only close connects that they create. This change should allow RowSets to be used with connection pool implementations based on JDBC 1.x drivers included missing EchoListener.java for example 5 The three JDBCTM RowSet implementations in this release demonstrate some of the many possibilities for implementing the javax.sql.RowSet interface, which is part of the JDBC 2.0 Optional Package API. The three example implementations in this release are:CachedRowSet -- a rowset that can be used to Send a set of rows across a network Send data to a thin client Add scrollability and updatability to result set data WebRowSet -- an extension of CachedRowSet that can be used to send a rowset across a network in XML format JDBCRowSet -- a rowset that can be used to encapsulate a JDBCTM driver as a Java BeansTM component Developers cannot redistribute the binary software in commercial products.

first read it out of the ResultSet and put it into another data type that's actually Serializable.

Send a set of rows across a network
Send data to a thin client
Add scrollability and updatability to result set data
WebRowSet -- an extension of CachedRowSet that can be used to send a rowset across a network in XML format
JDBCRowSet -- a rowset that can be used to encapsulate a JDBCTM driver as a Java BeansTM component

这篇文章讲了具体应用
transient ResultSet rs = stmt.executeQuery("SELECT * FROM EMPLOYEES");
CachedRowSet crs = new CachedRowSet();
crs.populate(rs);
这样就可以序列化了，在反序列化的时候执行相反操作就可以了
