You can disassemble a PDF document by passing it to the Assembler
service. Typically, this task is useful when the PDF document was
originally created from many individual documents, such as a collection
of statements. In the following illustration, DocA is divided into
multiple resultant documents, where the first level 1 bookmark on
a page identifies the start of a new resultant document.
To disassemble a PDF document, ensure that the PDFsFromBookmarks element
is located in the DDX document. The PDFsFromBookmarks element
is a resultant element and can be only a child element of the DDX element.
It does not have a result attribute because it
can result in the generation of multiple documents.
The PDFsFromBookmarks element causes a single document
to be generated for each level 1 bookmark in the source document.
For the purpose of this discussion, assume the following DDX
document is used.
<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDFsFromBookmarks prefix="stmt">
<PDF source="AssemblerResultPDF.pdf"/>
</PDFsFromBookmarks>
</DDX>
Remarque : When passing a single PDF document to the Assembler
service and getting back a single document, you can invoke the invokeOneDocument operation.
However, to disassemble a PDF document, use the invokeDDX operation
because although one input PDF document is passed to the Assembler
service, the Assembler service returns a collection object that
contains one or more documents.
Summary of stepsTo disassemble a PDF document, perform the following tasks:
Include project files.
Create a PDF Assembler client.
Reference an existing DDX document.
Reference a PDF document to disassemble.
Set run-time options.
Disassemble the PDF document.
Save the disassembled PDF documents.
Include project filesInclude the necessary files in your development
project. If you are creating a client application by using Java,
include the necessary JAR files. If you are using web services,
ensure that you include the proxy files.
The following JAR
files must be added to your project’s class path:
adobe-livecycle-client.jar
adobe-usermanager-client.jar
adobe-assembler-client.jar
adobe-utilities.jar (required if LiveCycle is deployed
on JBoss)
jbossall-client.jar (required if LiveCycle is deployed
on JBoss)
if LiveCycle is deployed on a
supported J2EE application server that is not JBoss, you must replace
adobe-utilities.jar and jbossall-client.jar with JAR files that
are specific to the J2EE application server on which LiveCycle
is deployed.
Create a PDF Assembler clientBefore you can programmatically
perform an Assembler operation, you must create an Assembler service
client.
Reference an existing DDX documentA DDX document must be referenced
to disassemble a PDF document. This DDX document must contain the PDFsFromBookmarks element.
Reference a PDF document to disassembleTo disassemble a PDF document,
reference a PDF file that represents the PDF document to disassemble.
When passed to the Assembler service, a separate PDF document is
returned for each level 1 bookmark in the document.
Set run-time optionsYou can set run-time options that control
the behaviour of the Assembler service while it performs a job.
For example, you can set an option that instructs the Assembler
service to continue processing a job if an error is encountered.
Disassemble the PDF documentAfter you create the Assembler service
client, reference the DDX document, reference a PDF document to
disassemble, and set run-time options, you can disassemble a PDF
document by invoking the invokeDDX method. Provided
that the DDX document contains instructions to disassemble the PDF
document, the Assembler service returns disassembled PDF documents within
a collection object.
Save the disassembled PDF documentsAll disassembled PDF documents
are returned within a collection object. Iterate through the collection
object and save each PDF document as a PDF file.
Disassemble a PDF document using the Java APIDisassemble a PDF document by using the Assembler Service
API (Java):
Include project files.
Include client JAR files,
such as adobe-assembler-client.jar, in your Java project’s class
path.

Reference an existing DDX document.
Create
a java.io.FileInputStream object that represents
the DDX document by using its constructor and passing a string value that
specifies the location of the DDX file.
Create a com.adobe.idp.Document object by
using its constructor and passing the java.io.FileInputStream object.
Reference a PDF document to disassemble.
Create
a java.util.Map object that is used to store input
PDF documents by using a HashMap constructor.

by using its constructor and passing the location of the PDF document
to disassemble.
Create a com.adobe.idp.Document object and
pass the java.io.FileInputStream object that contains
the PDF document to disassemble.
Add an entry to the java.util.Map object
by invoking its put method and passing the following
arguments:
A string value that represents the key
name. This value must match the value of the PDF source element
specified in the DDX document.
A com.adobe.idp.Document object that contains
the PDF document to disassemble.
Set run-time options.
Create an AssemblerOptionSpec object
that stores run-time options by using its constructor.
Set run-time options to meet your business requirements by invoking
a method that belongs to the AssemblerOptionSpec object.
For example, to instruct the Assembler service to continue processing
a job when an error occurs, invoke the AssemblerOptionSpec object’s setFailOnError method
and pass false.
Disassemble the PDF document.
Invoke the AssemblerServiceClient object’s invokeDDX method
and pass the following required values:
A com.adobe.idp.Document object
that represents the DDX document to use
A java.util.Map object that contains the
PDF document to disassemble
A com.adobe.livecycle.assembler.client.AssemblerOptionSpec object
that specifies the run-time options, including the default font
and the job log level
The invokeDDX method
returns a com.adobe.livecycle.assembler.client.AssemblerResult object
that contains the disassembled PDF documents and any exceptions
that occurred.
Save the disassembled PDF documents.
To obtain the
disassembled PDF documents, perform the following actions:
Invoke the AssemblerResult object’s getDocuments method.
This returns a java.util.Map object.
Iterate through the java.util.Map object
until you find the resultant com.adobe.idp.Document object.
Invoke the com.adobe.idp.Document object’s copyToFile method
to extract the PDF document.
Disassemble a PDF document using the web service APIDisassemble a PDF document by using the Assembler Service
API (web service):
Include project files.
Create a Microsoft .NET
project that uses MTOM. Ensure that you use the following WSDL definition
when setting a service reference: http://localhost:8080/soap/services/AssemblerService?WSDL&lc_version=9.0.1.
Remarque : Replace localhost with the IP
address of the server hosting LiveCycle.
Create a PDF Assembler client.
Create an AssemblerServiceClient object
by using its default constructor.
Create an AssemblerServiceClient.Endpoint.Address object
by using the System.ServiceModel.EndpointAddress constructor.
Pass a string value that specifies the WSDL to the LiveCycle service (for example, http://localhost:8080/soap/services/AssemblerService?blob=mtom).
You do not need to use the lc_version attribute.
This attribute is used when you create a service reference.
Create a System.ServiceModel.BasicHttpBinding object
by getting the value of the AssemblerServiceClient.Endpoint.Binding field.
Cast the return value to BasicHttpBinding.
Set the System.ServiceModel.BasicHttpBinding object’s MessageEncoding field
to WSMessageEncoding.Mtom. This value ensures that
MTOM is used.
Enable basic HTTP authentication by performing the following tasks:
Assign the LiveCycle user name to the field AssemblerServiceClient.ClientCredentials.UserName.UserName.
Assign the corresponding password value to the field AssemblerServiceClient.ClientCredentials.UserName.Password.
Assign the constant value HttpClientCredentialType.Basic to
the field BasicHttpBindingSecurity.Transport.ClientCredentialType.
Assign the constant value BasicHttpSecurityMode.TransportCredentialOnly to
the field BasicHttpBindingSecurity.Security.Mode.
Reference an existing DDX document.
Create
a BLOB object by using its constructor. The BLOB object
is used to store the DDX document.
Create a System.IO.FileStream object by
invoking its constructor. Pass a string value that represents the
file location of the DDX document and the mode in which to open
the file.
Create a byte array that stores the content of the System.IO.FileStream object.
You can determine the size of the byte array by getting the System.IO.FileStream object’s Length property.
Populate the byte array with stream data by invoking the System.IO.FileStream object’s Read method
and passing the byte array, the starting position, and the stream
length to read.
Populate the BLOB object by assigning its MTOM property
with the contents of the byte array.
Reference a PDF document to disassemble.
Create
a BLOB object by using its constructor. The BLOB object
is used to store the input PDF document. This BLOB object
is passed to the invokeOneDocument as an argument.

Create a MyMapOf_xsd_string_To_xsd_anyType object.
This collection object is used to store the PDF to disassemble.
Create a MyMapOf_xsd_string_To_xsd_anyType_Item object.
Assign a string value that represents the key name to the MyMapOf_xsd_string_To_xsd_anyType_Item object’s key field.
This value must match the value of the PDF source element specified
in the DDX document.
Assign the BLOB object that stores the PDF document
to the MyMapOf_xsd_string_To_xsd_anyType_Item object’s value field.
Add the MyMapOf_xsd_string_To_xsd_anyType_Item object
to the MyMapOf_xsd_string_To_xsd_anyType object.
Invoke the MyMapOf_xsd_string_To_xsd_anyType object’ Add method
and pass the MyMapOf_xsd_string_To_xsd_anyType object.
Set run-time options.
Create an AssemblerOptionSpec object
that stores run-time options by using its constructor.
Set run-time options to meet your business requirements by assigning
a value to a data member that belongs to the AssemblerOptionSpec object.
For example, to instruct the Assembler service to continue processing
a job when an error occurs, assign false to the AssemblerOptionSpec object’s failOnError field.
Disassemble the PDF document.
Invoke the AssemblerServiceClient object’s invokeDDX method
and pass the following values:
A BLOB object
that represents the DDX document that disassembles the PDF document
The MyMapOf_xsd_string_To_xsd_anyType object
that contains the PDF document to disassemble
An AssemblerOptionSpec object that specifies
run-time options
The invokeDDX method
returns an AssemblerResult object that contains
the job results and any exceptions that occurred.
Save the disassembled PDF documents.
To obtain the
newly created PDF documents, perform the following actions:
Access the AssemblerResult object’s documents field,
which is a Map object that contains the disassembled
PDF documents.
Iterate through the Map object to obtain each
resultant document. Then, cast that array member’s value to
a BLOB.
Extract the binary data that represents the PDF document
by accessing its BLOB object’s MTOM property.
This returns an array of bytes that you can write out to a PDF file.
