Help needed in geocoding through sdo_gcdr.geocode_addr_all

Question

Hi all,
I am using the below SQL for the same. I am able to use the below query
SELECT SDO_GCDR.GEOCODE('GEOSAMPLE',SDO_KEYWORDARRAY('CALIFORNIA PACIFIC MEDICAL CTR', 'US','92306'), 'US', 'DEFAULT') FROM DUAL;
but now I want to use geocode_addr_all but I am not sure which arguments I need to provide to GEOCODE-ADDR_ALL and SDO_KEYWORDARRAY? Is sdo_keywordarray is compulsory to have argument?
SELECT sdo_gcdr.geocode_addr_all('GEOSAMPLE', SDO_GEO_ADDR(0, SDO_KEYWORDARRAY(), '',
'BUCHANAN ST', NULL, NULL, 'SAN FRANCISCO', NULL, 'CA', 'US', '94115', NULL, '94115', NULL, '2333', NULL, NULL, 'F', 'F',
NULL, NULL, 'L', 0, 23599031, '??????????B281CP?', 4, 'DEFAULT', -122.43097, 37.79138), 15) FROM DUAL ;
I searched on the net but didn't find a java example for same. All about documentation only that is not clear how to use it. Please provide me some way or any useful link for the same.
Thanks.

1.
Earlier the code was using the below query
SELECT G.GC.LONGITUDE, G.GC.LATITUDE, G.GC.MATCHCODE FROM (SELECT SDO_GCDR.GEOCODE(?, SDO_KEYWORDARRAY(?,?,?,?,?,?,?,?,?,?),?,?) GC FROM DUAL) G
Now I need to get all the matching addresses for a single input. So I changed the query into the ...
SELECT sdo_gcdr.geocode_addr_all('GEOSAMPLE', SDO_GEO_ADDR(0, SDO_KEYWORDARRAY(5, 'E', '9th', 'Street', '', 'Kansas City', '', '', 'MO', '67530'), NULL,
NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, NULL, NULL, 'DEFAULT', 0, 0), 15) GC FROM DUAL ;
So I am planning to create a SDO_KEYWORDARRAY same as the earlier code and will use into the new query. Rest of the argument to SDO_GEO_ADDR I will place NULL. Is that correct or you suggest something else.
2. http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14255/sdo_geocode_concepts.htm#CIHGGJCG
This link is giving the idea about each argument of SDO_KEYWORDARRAY and according to this link it is describing 9 parameters. So is this the real number of arguments and sequence for our SDO_KEYWORDARRAY? If yes, then what format we are using in the above query having 10 arguments? and arguments are in sequence also as per the above link!!!
Even this query is also valid SDO_KEYWORDARRAY('CALIFORNIA PACIFIC MEDICAL CTR', 'US','92306') but again confusion in the argument?

Second query, I will get the result in the below form...
MDSYS.SDO_ADDR_ARRAY('MDSYS.SDO_GEO_ADDR(0),'null','null','null','null','KANSAS CITY','null','MO','US','64105','null','null','null','null','null','null','F','F','null','null','L',0,344973778,'??????????B281C??',10,'DEFAULT',-94.58302,39.10295,'???31131110??002?')','MDSYS.SDO_GEO_ADDR(0),'null','null','null','null','KANSAS CITY','null','MO','US','64164','null','null','null','null','null','null','F','F','null','null','L',0,780357721,'??????????B281C??',10,'DEFAULT',-94.64491,39.31105,'???31131110??002?')','MDSYS.SDO_GEO_ADDR(0),'null','null','null','null','KANSAS CITY','null','MO','US','64161','null','null','null','null','null','null','F','F','null','null','L',0,344805784,'??????????B281C??',10,'DEFAULT',-94.46238,39.16317,'???31131110??002?')','MDSYS.SDO_GEO_ADDR(0),'null','null','null','null','KANSAS CITY','null','MO','US','64012','null','null','null','null','null','null','F','F','null','null','L',0,344983779,'??????????B281C??',10,'DEFAULT',-94.54999,38.83666,'???31131110??002?')','MDSYS.SDO_GEO_ADDR(0),'null','null','null','null','KANSAS CITY','null','MO','US','64105','null','null','null','null','null','null','F','F','null','null','L',0,344973778,'??????????B281C??',10,'DEFAULT',-94.58302,39.10295,'???31131110??002?')')
How you will parse each address to get logitude/latitude? Will you do it through Java code or through SQL only without using pl-sql.
4. Will you suggest any java book that is using all these things?
Thanks a lot.
