Oracle.sql.BLOB as array

Question

Hi,
I have a database table(say MY_BLOB_TABLE.) having one blob column
I want to send each blob column as an attachment to a single email i.e. I for a particular case if I have 10 qualifying rows in MY_BLOB_TABLE,I want to send all these 10 blobs as different attachments with a SINGLE email.
I have the working code (from asktom) that allows me to send one attchment per email ..so I changed the code so that it takes array types to the things..
here is my code:
Database Type:
create or replace type xx_blobdata is varray(50) of blob;
create or replace type xx_attachedfile is varray(50) of varchar2(1000);
create or replace type xx_attachedfiletype is varray(50) of varchar2(1000);
Java Code
public class xx_attachments_mail
static String dftMime = "application/octet-stream";
static String dftName = "filename.dat";
public static oracle.sql.NUMBER
send(String from,
String to,
String cc,
String bcc,
String subject,
String body,
String SMTPHost,
oracle.sql.BLOB[] attachmentData,
String[] attachmentType,
String[] attachmentFileName);
PLSQL Wrapper
create or replace function xx_attachments_mail_send(
p_from in varchar2,
p_to in varchar2,
p_cc in varchar2,
p_bcc in varchar2,
p_subject in varchar2,
p_body in varchar2,
p_smtp_host in varchar2,
p_attachment_data in xx_blobdata,
p_attachment_type in xx_attachedfiletype,
p_attachment_file_name in xx_attachedfile) return number
as
language java name 'xx_attachments_mail.send( java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
java.lang.String,
oracle.sql.BLOB[],
java.lang.String[],
java.lang.String[]
) return oracle.sql.NUMBER';
Actual Call:
attachment_data :=xx_blobdata();
attachment_type :=xx_attachedfiletype();
attachment_name :=xx_attachedfile();
ret_code := xx_attachments_mail_send(
p_from => '[email protected]',
p_to => '[email protected]',
p_cc => NULL,
p_bcc => NULL,
p_subject => 'testing',
p_body => 'testing..',
p_smtp_host => 'myserver.com',
p_attachment_data => attachment_data,
p_attachment_type => attachment_type,
p_attachment_file_name => attachment_name);
Everything compiles. All objects are valid in database.But when I call I get the following error:
ORA-29531: no method send in class xx_attachments_mail
ORA-06512: at "XX_ATTACHMENTS_MAIL_SEND", line 1
Can anybody point out what is wrong that I am doing.
Thanks.

Devang,
You asked:
Can anybody point out what is wrong that I am doing?Yes, I can.
VARRAY maps to "java.sql.Array" or "oracle.sql.ARRAY".
You can find more details in the JDBC Developer's Guide and Reference which is part of the Oracle documentation, as well as the JDBC sample code which can be accessed from here:

Good Luck,
Avi.
