I am making an application that has a FileInput node that is pulling in a file from a directory to start with. I am calling a web service that requires a SOAP input as well as an attachment. After I have input the file, I set up the namespaces, headers, and request fields necessary to call the web service. I do not believe there are any problems here.

Next, I set up the file to be sent to the web service as an attachment. From the FileInput node, the file exists in the flow as a BLOB right now at InputRoot.BLOB.BLOB. I have seen that in order to send a file as an attachment in a request, I should to do the following (I have hardcoded some values for the sake of this explanation):

Code:
SET OutputRoot.SOAP.Attachment.{fileName}.MIME_Headers."Content-Type" = 'application/pdf;';
SET OutputRoot.SOAP.Attachment.{fileName}.MIME_Headers."Content-Transfer-Encoding" = 'binary';   
SET OutputRoot.SOAP.Attachment.{fileName}.MIME_Headers."Content-Id" = 'Here is the name of a file.pdf';
SET OutputRoot.SOAP.Attachment.{fileName}.BLOB.BLOB = InputRoot.BLOB.BLOB;


When I try to call the web service, I am receiving the following error:

"invalid data for SOAP.Attachment.<Content-Id>.BLOB"



I figured that the BLOB that is in the InputRoot would be sufficient to pass into web service, but it doesn't seem to be so. Am I missing something? Please let me know if I didn't explain this well enough as well and I can try to elaborate.

Good problem description, but please quote the entire error message, accurately and in full. Include the id of the error message ('BIP' + 4 digits).

Also, the title of your post could be a lot better. You are asking about SOAP with attachments, not the FileInput node (the BLOB in your SOAP message tree could have come from anywhere, and you would still have the same problem)

Also, you have not mentioned whether you want to use MTOM. That could be very relevant.

Understood; I will work to better my replies in the future using your points as a guideline.

I think for my purposes, I should be using SwA rather than MTOM.

Here is the error, with the web service name removed:

The error number is BIP3608. The full text of that error is available here: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_10.0.0/com.ibm.etools.mft.bipmsgs.doc/ay_bip3.htm

It says:
Quote:

BIP3608
The logical tree includes an incorrectly formatted Attachment <insert_1>.
Severity
20 : Error
Explanation
The SOAP logical tree has an Attachment subtree with children corresponding to any attachments in a SOAP with Attachments document. Each child is named after the Content-Id of the corresponding MIME part and must have a child called BLOB as generated by the BLOB parser with a child also called BLOB and containing valid bytearray data.
Response
Check the logical tree and ensure the Attachment data is represented correctly.

Your ESQL looks correct to me, but I may be missing something. My next step would be to check the structure of the message tree that is being passed to the SOAPRequest node. Attach the debugger or (better) insert a Trace node and set its Pattern property to ${Root}. Check the tree structure against the structure specified in the Knowledge Center.

Here is the Trace that I am looking at. I removed a lot of the BLOB text. It looks to match up with the tree structure of that of the Knowledge Center.

It is important to note that I also tried commenting out the ESQL that attaches the attachment for just a moment to test the integrity of the SOAP structure.
I got an error response from the web service at least, so this attachment is definitely the problem.

Yes, I agree that the structure looks correct.

Not sure whether the value 'Document Name Here' is just to maintain confidentiality. I would try using an id without spaces, if you haven't tried that already.

Could it be as easy as adding in the content-type of the attachment: application/binary ?? The error seems to point that way...
