public class BlobJDBCAdapter
extends DefaultJDBCAdapter

This JDBCAdapter inserts and extracts BLOB data using the getBlob()/setBlob() operations. This is a little more involved since to insert a blob you have to: 1: insert empty blob. 2: select the blob 3: finally update the blob with data value. The databases/JDBC drivers that use this adapter are:
