**** NOTE: The following is a code that has been cut from a program. Use this code at your own risk. ****


**** to map spatial data types to object in Java:


    Map CustomTypeMap = null;
    String MainDB = "jdbc:informix-sqli://"+ "SERVERHOST" + ":" + "SERVERPORT"; 
    Properties MainP = new Properties(); 
    MainP.put("INFORMIXSERVER", "DBSERVERNAME" ); 
    MainP.put("database", "DBNAME" ); 
    MainP.put("user", "USERNAME" ); 
    MainP.put("password", "PASSWORD"  ); 
    try
    {
         Connection MC = null;
         Statement ST = null;
                
         MC = DriverManager.getConnection( MainDB, MainP); 
         ST = MC.createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, 
                                  ResultSet.CONCUR_READ_ONLY); 
         System.out.println("Connected");
         CustomTypeMap = MC.getTypeMap();
         CustomTypeMap.put("st_geometry",Class.forName("ST_WKBGeometry"));
         MC.setTypeMap( CustomTypeMap ); 
    }
    catch( Exception e )
    { System.out.println("Warning: Could not make connection to DB : " + (i+1) ); }


**** to get a spatial data, you need to use st_asbinary() function like the following:
    QueryStr = "select station_name, st_asbinary( station_location ) from stations; "

**** and then to read the data:
use the getColumnTypeName() function and if it is similar to "ST_geometry", then map the object. 
Example:
            while( QueryResult.next() ) 
            { 
                for( int i=1; i<=QueryResultMetaData.getColumnCount(); i++)
                {
                    String ColumnType = QueryResultMetaData.getColumnTypeName( i );
                    String Val = "";
                    if( ColumnType.equalsIgnoreCase( "ST_geometry" ) )
                    {
                        Geometry = (ST_WKBGeometry)QueryResult.getObject( i ); 
                        Val = Geometry.toString();
                    }
                    else 
                        Val = ""+QueryResult.getString( i );
                }
            }
