Problem with CachedRowset

[Maria Peter]

I tried to use Cached RowSet for sybase.I'm using sybase 12.5
and the jdbc driver jconn2.jar is 5.5 version.
I get the following exception:
Caused by: com.sybase.jdbc2.utils.UnimplementedOperationException:
The method com.sybase.jdbc2.tds.RowFormatToken.getSchemaName has not been completed
and should not be called.
Looks like the driver does not support the rowset implementation.
Does it work with DB2?
Or can you please tell me which is the best way to cache data for DB2 and sybase database
Thanks for your help
Maria
