 
                A serialized mapping in the Java programming language of an SQL 
 
DATALINK value. A 
DATALINK value 
 references a file outside of the underlying data source that the
 data source manages.
 
 RowSet implementations can use the method RowSet.getURL
 to retrieve a java.net.URL object, which can be used
 to manipulate the external data.
 
      java.net.URL url = rowset.getURL(1);
