Including document in Attachment of IP_MESSAGE_TYPE to B2B

Question

Dear Reader,
I am using SOA suite 10.1.3.4. and B2B 10g configured in Suse.
I have made a BPEL proces that enqueues messages using an AQ adapter to the B2B database. For this I need to fill in the IP_MESSAGE_TYPE (payload header) that is required by EBxml that is set in the B2B Application. I have set the MSG_ID, FROM_PARTY, TO_PARTY, DOCTYPE_NAME, DOCTYPE_REVISION, ACTION_NAME, MSG_TYPE occording to the configurations done in the B2B application. This works perfectly and the message is picked up by the B2B application.
During new requirement I need to send an attachment to the B2B application that communicted this to the trading partner (using EBxml). THe moment I fill in the attachment the message produces errors in the B2B Application and I don't know what I am doing wrong. I would like to know if somebody can tell me in steps how I need to fill in the attachment in the payload header. I have tried the following:
1. Using an assign activity to fill the attachment field in the payload header with the expression: '/home/oracle/b2b/attachments/inbound/example.xml'
The error 'Unable to create the protocol specific B2B message' arrise in the B2B application.
2. I have followed the steps in link:
https://metalink2.oracle.com/metalink/plsql/f?p=130:14:4427741198166476399::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,754149.1,1,1,1,helvetica
I have created the xsd AttachmentsDescriptor.xsd in my local bpel process and assign the below XML fragment to the attachment field in the payload header.
<Attachments xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="AttachmentsDescriptor.xsd" version="1.0" boundary="boundary---">
<AttachmentPart>
<Location>file:///home/oracle/b2b/attachments/inbound/example.xml</Location>
<Content-Type>
<Top-Level-Type>application</Top-Level-Type>
<Sub-Type>xml</Sub-Type>
</Content-Type>
</AttachmentPart>
</Attachments>
This time no error occured everything seem to work, but in the B2B database there is no attachment specified in the wire message.
I hope somebody can explain me what I am doing wrong and what the steps in BPEL/B2B are to fix my problem.
Thanks for your time.

Answer 1

Hi Anuj,
Thanks for your reply. I have tested it on the server and it works. I am now busy to make it work with my BPEL proces. I am doing the following:
1. I am using a file adapter to store the sample.xml file on the configurated directorie specified in "oracle.tip.adapter.b2b.attachments.dir"
2. I pass the name of the file in this case Sample.xml in the field Attachment of IP_MESSAGE_TYPE (other mandatory fields of IP_MESSAGE_TYPE are filled)
My question is if I can make it work without step 1 to prevent extra I/O on the server. I would like to fill the Attachment of IP_MESSAGE_TYPE in such a way that I don't need the Sample.xml and that my attachment is picked up directly from the server. I am wondering how I can achieve this (if its possible).
My last question is if there is any good documentation for B2b 10g how I should configure the environment to prevent connections being kept alive when enqueuing message using AQ adapter.
Thanks for your time and help so far.
Regards,
Sander
