How to assemble multiple XDP fragments using the Java API

Level 2
Level 2

Hi All,


I am trying to assemble multiple fragments to create a one master xdp file so that I can use the same to generate the PDF.

I have tried the following documentation for the same;

Below is my code;

private Document assemblerService(SlingHttpServletRequest request)
{"--------------inside assemblerService method------------------");

ServiceClientFactory scf = scfProvider.getDefaultServiceClientFactory();
AssemblerServiceClient assemblerClient = new AssemblerServiceClient(scf);

StringBuffer ddxDoc = new StringBuffer();
ddxDoc.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
ddxDoc.append("<DDX xmlns=\"\">");
ddxDoc.append("<XDP result=\"tuc018result.xdp\">");
ddxDoc.append("<XDP source=\"tuc018_template_flowed.xdp\">");
ddxDoc.append("<XDPContent insertionPoint=\"ddx_fragment\" source=\"frgTest.xdp\" fragment=\"frgTest\" required=\"false\"/>");
ddxDoc.append("</XDP></XDP></DDX>"); is = new;
com.adobe.idp.Document myDDX = new com.adobe.idp.Document(is);

ResourceResolver resourceResolver = request.getResourceResolver();
String xdpDoc1 = "/content/dam/xdps/frgTest.xdp";
Resource res = resourceResolver.getResource(xdpDoc1);
Asset asset = res.adaptTo(Asset.class);
Resource original = asset.getOriginal();
InputStream xdpIS = original.adaptTo(InputStream.class);

com.adobe.idp.Document frgXdpDoc = new com.adobe.idp.Document(xdpIS);

//Create a Map object to store the PDF source documents
Map inputs = new HashMap();

//Place two entries into the Map object

//Create an AssemblerOptionsSpec object
AssemblerOptionSpec assemblerSpec = new AssemblerOptionSpec();

//Submit the job to Assembler service
AssemblerResult jobResult = null;
try {
jobResult = assemblerClient.invokeDDX(myDDX,inputs,assemblerSpec);
catch (Exception e1) {
java.util.Map allDocs = jobResult.getDocuments();
//Retrieve the resulting PDF document from the Map object
Document outDoc = null;
//Iterate through the map object to retrieve the resulting PDF document
for (Iterator i = allDocs.entrySet().iterator(); i.hasNext();) 
// Retrieve the Map object's value
Map.Entry e = (Map.Entry);
Object o = e.getValue();
if (o instanceof Document) {
//Cast the Object to a Document
outDoc = (Document)o;
return outDoc;

Here in this code, I am using one xdp fragment to test if it can return a master xdp doc.

Please check and let me know if I am missing anything. Using this code I am getting following error;
