Assembler Service to merge pdfs - help required

[Dileepblr]

This is the ddx spec that I am using.

<?

xml version="1.0" encoding="UTF-8"?>

<

DDX xmlns="http://ns.adobe.com/DDX/1.0/">

<

PDF result="out.pdf">

<

PDF source="map.pdf"/>

<

PDF source="directions.pdf"/>

</

PDF>

</

DDX>

Dim ddxBLOB As New AssemblerService.BLOB

Dim file1BLOB As New AssemblerService.BLOB

Dim file2BLOB As New AssemblerService.BLOB

Dim svcAssembler As New AssemblerService.AssemblerServiceService

ddxBLOB.binaryData = GetPdfContentAsByteArray(sDDXFileName)

file1BLOB.binaryData = GetPdfContentAsByteArray(sFile1Name)

file2BLOB.binaryData = GetPdfContentAsByteArray(sFile2Name)

inputMap(0) =

New AssemblerService.mapItem

inputMap(0).key = "map.pdf"

inputMap(0).value = file1BLOB

inputMap(1) =

New AssemblerService.mapItem

inputMap(1).key = "directions.pdf"

inputMap(1).value = file2BLOB

svcAssembler.Credentials = userCredential

inputMap(0) =

New AssemblerService.mapItem

inputMap(0).key = "map.pdf"

inputMap(0).value = file1BLOB

inputMap(1) =

New AssemblerService.mapItem

inputMap(1).key = "directions.pdf"

inputMap(1).value = file2BLOB

'Create an AssemblerOptionsSpec object

Dim assemblerSpec As New AssemblerService.AssemblerOptionSpec

assemblerSpec.failOnError =

False

'Send the request to the Assembler Service

Dim assemblerRes As New AssemblerService.AssemblerResult

assemblerRes = svcAssembler.invoke(ddxBLOB, inputMap, assemblerSpec)

It throws the following exception at this point

"

  ex.Message "com.adobe.livecycle.assembler.client.OperationException: ALC-ASM-S00-002: Failed to execute the DDX - error messages provided. Caused by: javax.xml.bind.UnmarshalException Caused by: org.xml.sax.SAXParseException: Content is not allowed in trailing section.; nested exception is:
com.adobe.livecycle.assembler.client.OperationException: ALC-ASM-S00-002: Failed to execute the DDX - error messages provided." String

"

I checked the ddx  file for any whitespace and for me it looks fine.Any tips as to why this exception happens?

Not sure.  DDX can be funny and there is no way that I know of to debug it easily.  Adobe provides you a DDX tool, but I have had mixed results with it.

But, it might be easier of your wrote all the assembly code in a LC process and then call that process from Java.  Your Java call would only have 2 inputs and 1 output, all documents.

Thanks for your input.

I am using ES2 in a .NET environment.I am still trying to figure our what is the actual problem with the ddx content that I am using.I scrutinised it well to see that it doesn't have any whitespaces that can cause this to error out while parsing.And its not huge too..It just 4 few lines of text saved as a XML file.

The ddx file should have the extension as .xml..is that right?
