Assembler ddx issue

[Giucip]

Hi,

I'm trying to merge two pdf files, using the ddx assembler:

<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDF result="out2.pdf">
       <PDF source="inDoc1"/> 
       <PDF source="inDoc2"/>
</PDF>
</DDX>

I have two ddx keys

inDoc1 --> /process_data/@outData

inDoc2 --> /process_data/@inDocument

but I have the following issue

com.adobe.livecycle.assembler.client.ProcessingException: ALC-ASM-S00-002: Failed to execute the DDX - error messages provided.

The log states that there is an unknown source and has a null pointer exception.  This is usually caused when one or more of the input objects are not set.  In other words, it looks like one of your document objects are empty.

Since you are mapping:

inDoc1 --> /process_data/@outData

inDoc2 --> /process_data/@inDocument

Can you check that they are both populated before the Assembler step?

[Giucip]

Thanks for your answer...I checked it and they were set.

I did a more simple test, one assembler block with this ddx command

<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/" >
    <PDF result="out.pdf">
        <PDF source="in1.pdf"/>
        <PDF source="in1.pdf"/>
    </PDF>
</DDX>

in1.pdf is a ddx key -->/process_data/@inDocument

where inDocument is a document input variable

same error

[Hodmi]

Interesting. I did a quick test on one of my LC 8.2 servers and your DDX seems to be fine.  The one difference is that I have the Input DDX Document set to "literal" and not "template".

[Giucip]

Thanks for your help...I found out that the problem was with pdf/a files...is it possible?

I have to convert to pdf, isn't it? Is it possible using ddx command?

thanks

PDF/A file should work fine, although I'm not sure that the result of combining them will still be PDF/A compliant document.  Can you share one of the files that is causing you problems?

[Giucip]

I  think the problem is about pdf/a

made  by openoffice writer.

http://dl.dropbox.com/u/3220010/TEST.pdf

I don't know how to attach here a file :-(

[Hodmi · Accepted solution]

Yes, it looks like there is something wrong with the PDF.

I can open the document with Acrobat, but it fails with any LiveCycle operations.  Acrobat is quite forgiving of documents that don't follow the PDF spec exactly - LiveCycle is much less forgiving.

I tried to optimize the document which sometimes fixes bad PDFs, but it didn't work in this case.  The only way I was able to do it was to first convert the document to a PS document (using the ConvertPdfService) then back to a PDF (using the DistillerService).  Its pretty ugly, but it did "fix" the PDF so it could be assembled.

Unless you can get a "valid" pdf, then this may be your only recourse.
