ORA-00932 when trying to pass ARRAY from Java SP to PL/SQL

Question

Hi all
I am trying to pass ARRAYs back and forth between PL/SQL and Java stored procedures. But I keep getting:
ORA-00932: inconsistent datatypes: expected a return value that is an instance of a user defined Java class convertible to an Oracle type got an object that could not be converted
Here's my PL/SQL:
create or replace type CONTENTP.sentences_array as VARRAY(1000) of CLOB
-- I've also tried .. as TABLE of CLOB and varray/table of VARCHAR2
declare
proc_clob CLOB;
arr SENTENCES_ARRAY;
begin
SELECT document_body
into proc_clob
from documents
where document_id = 618784;
arr := processdocument.sentencesplit (proc_clob);
end;
PROCESSDOCUMENT package definition:
CREATE OR REPLACE PACKAGE CONTENTP.PROCESSDOCUMENT AS
FUNCTION sentenceSplit(Param1 CLOB)
return SENTENCES_ARRAY
AS
LANGUAGE java
NAME 'com.contentp.documents.ProcessDocument.sentenceSplit(oracle.sql.CLOB) return oracle.sql.ARRAY';
FUNCTION removeHTML(Param1 CLOB)
return CLOB
AS
LANGUAGE java
NAME 'com.contentp.documents.ProcessDocument.removeHTML(oracle.sql.CLOB) return oracle.sql.CLOB';
end;
Java sentenceSplit code:
public static oracle.sql.ARRAY sentenceSplit ( CLOB text) throws IOException, SQLException
Connection conn = new OracleDriver().defaultConnection();
String[] arrSentences = sent.getsentences ( CLOBtoString (text) );
ArrayDescriptor arrayDesc =
ArrayDescriptor.createDescriptor ("SENTENCES_ARRAY", conn);
ARRAY ARRSentences = new ARRAY (arrayDesc, conn, arrSentences);
return ARRSentences;
I have confirmed that the String[] arrSentences contains a valid string array. So the problem seems to be the creation and passing of ARRSentences.
I have looked at pages and pages of documents and example code, and can't see anything wrong with my declaration of ARRSentences. I'm at a loss to explain what's wrong.
Thanks in advance - any help is much appreciated!

I am trying to do something similar but seems like getting stuck at registerOutParameter for this.
Type definition:
CREATE OR REPLACE
type APL_CCAM9.VARCHARARRAY as table of VARCHAR2(100)
Java Stored Function code:
public static ARRAY fetchData (ARRAY originAreaCds, ARRAY serviceCds, ARRAY vvpcs) {
Connection connection = null;
     ARRAY array = null;
     try {
     connection = new OracleDriver ().defaultConnection();
     connection.setAutoCommit(false);
ArrayDescriptor adString = ArrayDescriptor.createDescriptor("VARCHARARRAY", connection);
String[] result = new String [2];
result[0] = "Foo";
result[1] = "Foo1";
array = new ARRAY (adString, connection, result);
connection.commit ();
return array;
} catch (SQLException sqlexp) {
try {
connection.rollback();
} catch (SQLException exp) {
return array;
Oracle Stored Function:
function FETCH_TRADE_DYN_DATA (AREA_CDS IN VARCHARARRAY, SERVICE_CDS IN VARCHARARRAY,VV_CDS IN VARCHARARRAY) return VARCHARARRAY AS LANGUAGE JAVA NAME 'com.apl.ccam.oracle.js.dalc.TDynAllocation.fetchData (oracle.sql.ARRAY, oracle.sql.ARRAY, oracle.sql.ARRAY) return oracle.sql.ARRAY';
Java Code calling Oracle Stored Procedure:
ocs = (OracleCallableStatement) oraconn.prepareCall(queryBuf.toString());
               ArrayDescriptor adString = ArrayDescriptor.createDescriptor("VARCHARARRAY", oraconn);
               String[] originAreaCds = sTDynAllocationVO.getGeogAreaCds();
               ARRAY areaCdArray = new ARRAY (adString, oraconn, originAreaCds);
               ocs.registerOutParameter(1, OracleTypes.ARRAY);
               ocs.setArray (2, areaCdArray);
               String[] serviceCds = sTDynAllocationVO.getServiceCds();
               ARRAY serviceCdsArray = new ARRAY (adString, oraconn, serviceCds );
               ocs.setArray (3, serviceCdsArray);
               String[] vvpcs = sTDynAllocationVO.getVesselVoyagePortCdCallNbrs();
               ARRAY vvpcsArray = new ARRAY (adString, oraconn, vvpcs);
               ocs.setArray (4, vvpcsArray);
ocs.execute();
ARRAY results = ocs.getARRAY(1);
Error I get:
Parameter Type Conflict: sqlType=2003
Thanks for help in advance.
