Extract attachments as separated files

[Former Member]

Hi all,

I need to extract attachments from the Pdf file as separated files while the user uploades a pdf file to the SAP system.

I'm using an offline scenario (JAVA).

May be PdfObject is what I need, but I don't know how exactly I can do this.

Thanks,

Michael Beilin

the same methods of the PDf Object are available for Java and ABAP because the are accesed via a SOAP call from both stacks, so this should work

thats abap coding

• Create PDF Object.

l_pdfobj = l_fp->create_pdf_object( connection = p_dest ).

• Set document. l_pdf is the PDF data including the attachments

l_pdfobj->set_document( pdfdata = l_pdf ).

• Set task to get attachments.

l_pdfobj->set_task_getattachments( ).

• Execute, call ADS.

l_pdfobj->execute( ).

• Get result.

l_attachments = l_pdfobj->get_attachments( ).

hope it helps

Hi,

I'm not familiar with ABAP coding, I'm using WebDynpro for Java.

I have the context attribute of binary type that is bined to data attribute of FileUpload element.

ABAP coding:

• Create PDF Object.

l_pdfobj = l_fp->create_pdf_object( connection = p_dest ).

How can I do the same in Java?

Thanks

Have a look at [Interface IWDPDFDocumentAttachmentList|http://help.sap.com/javadocs/NW04S/current/wd/com/sap/tc/webdynpro/clientserver/adobe/pdfdocument/api/IWDPDFDocumentAttachmentList.html]. It may be the one you are looking for.

hi,

Michael Chytracek, one of our java developers has given me the following hint:

Important:use the "new!" API u201CPDFDocumentu201D because the old u201CPDFObjectu201D API can not handle attachments. Attachment API for the Interactive form have been made available with the following:

NW04s SP09 Web Dynpro Runtime + hotfix release (Note: 982023)

NW04s SP10 Web Dynpro Runtime + hotfix release (Note: 984868)

SP11 onwards > Base SAP release

IWDPDFDocumentAccessibleContext pdfContext = WDPDFDocumentFactory.getDocumentHandler().getDocumentAccessibleContext();
pdfContext.setPDF(pdf);
         
IWDPDFDocument pdfDocument = pdfContext.execute();
IWDPDFDocumentAttachment[]     attachments = pdfDocument.getAllAttachments();
for(int i = 0; i < attachments.length; i++){
    IWDPDFDocumentAttachment att = attachments<i>;
    .......
    }

Hi Norbert,

Thanks for your help. I have try your solution, but without success.

In method

pdfContext.setPDF(pdf);

"pdf" parameter is of type "binary" that is binded to FileUpload Element also.

But in attachments.length I get 0 value(the pdf file has 2 attachments).

Have any idea what may be the problem?

Thanks,

Michael Beilin

could you post an example of the content of the attachment array?

do the attributes look like this??

NAME

FILENAME

MIMETYPE

FILESIZE

CREATIONTIME

MODIFICATIONTIME

DESCRIPTION

DATA

[Former Member · Accepted solution]

Hi Norbert,

I have that structure in every att (attachments instance), but attachments is empty!

I see in debugger that pdfContext.setPDF(my binary source) is filled correctly with data from pdf file.

And after

IWDPDFDocument pdfDocument = pdfContext.execute();

IWDPDFDocumentAttachment[] attachments = pdfDocument.getAllAttachments();

commands I see that attachments.length = 0.

May be something missing?

Thanks

did you be aware:

NW04s SP09 Web Dynpro Runtime + hotfix release (Note: 982023)

NW04s SP10 Web Dynpro Runtime + hotfix release (Note: 984868)

SP11 onwards > Base SAP release

??

stupid question: are there attachments in the pdf, which ones??

[Former Member · Accepted solution]

Hi Norbert,

Yes, there are 2 attachments in the pdf file.

Retrieving data from pdf is working also fine for me.

I use the following command for that:

WDInteractiveFormHelper.transferPDFDataIntoContext(binaryPdfSource, pdfDataSource);

And we are in NW04s SP 15.

Thanks for help

hm, no idea, perhaps attachments are not supported for java stack, or just for this release...perhaps michael could give it a try again...

See if below blog helps:-

Hi, Chintan

Nice blog.But, here you need to go to the backend R/3 to extract the attachemnts from the pdf.

PDFObjects are available in webdynpro for Java as well. So, there has to be a way to replicate the attachment-extracting functionality (that was achieved in R/3), in webdynpro for java too.

Thanks,

Michael Beilin

there is a mthod for the PDF object - must be the same for java --> get_attachments()

you get an array of the attachments

[NoJo]

have a look at report FP_PDF_TEST_15 in your system...

I'm using WebDynpro for JAVA ,not ABAP
