Loding clob from file-ORA-22994

Question

declare
dest_clob CLOB;
src_clob BFILE ;
dst_offset number :=1;
src_offset number :=1;
lang_ctx number := DBMS_LOB.DEFAULT_LANG_CTX;
warning number;
type filesarray IS VARRAY(5) OF VARCHAR2(50);
names filesarray;
l_stmt CLOB;
BEGIN
names := filesarray('p1.xml','p2.xml','p3.xml','p4.xml','p5.xml');
FOR I IN 1..names.count LOOP
--DBMS_OUTPUT.ENABLE(100000);
dest_clob :='';
src_clob := BFILENAME('PCSORADIR',names(i));
Insert into TEST (NAME,VALUE) values
(SUBSTR(names(i),1,INSTR(names(i),'.xml',1,1)-1),EMPTY_CLOB())
RETURNING VALUE INTO dest_clob;
DBMS_LOB.OPEN(src_clob, DBMS_LOB.LOB_READONLY);
DBMS_OUTPUT.PUT_LINE(names(i));
DBMS_OUTPUT.PUT_LINE(DBMS_LOB.GETLENGTH(src_clob));
DBMS_LOB.LoadCLOBFromFile(
DEST_LOB => dest_clob
, SRC_BFILE => src_clob
, AMOUNT => DBMS_LOB.GETLENGTH(src_clob)
, DEST_OFFSET => dst_offset
, SRC_OFFSET => src_offset
, BFILE_CSID => DBMS_LOB.DEFAULT_CSID
, LANG_CONTEXT => lang_ctx
, WARNING => warning
);DBMS_OUTPUT.PUT_LINE('test');
dbms_lob.filecloseall;
COMMIT;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Loaded XML File using DBMS_LOB.LoadCLOBFromFile: (ID=1001).');
END;
Its giving error-ORA-22994: source offset is beyond the end of the source LOB
If i am loading these files individually(with out any loop) its loading with out any error.

If i am loading these files individually(with out any loop) its loading with out any error.Have you read the documentation on loadclobfromfile? http://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978

dest_offset
(IN) Offset in characters in the destination CLOB (origin: 1) for the start of the write. *(OUT) The new offset in characters right after the end of this load, which is also where the next load should start*. It always points to the beginning of the first complete character after the end of load. If the last character is not complete, offset goes back to the beginning of the partial character.
src_offset
(IN) Offset in bytes in the source BFILE (origin: 1) for the start of the read. *(OUT)Offset in bytes in the source BFILE right after the end of this read, which is also where the next read should begin*.
