You can assemble PDF documents that contain unique page
identifiers by using Bates numbering.
Bates numbering
is
a method of applying unique identifies to a batch of related documents.
Each page in the document (or set of documents) is assigned a Bates
number that uniquely identifies the page. For example, manufacturing
documents that contain bill of material information and are associated
with the production of an assembly can contain an identifier. A
Bates number contains a sequentially incremented numeric value and
an optional prefix and suffix. The prefix + numeric + suffix is
referred to as a
bates pattern
.
The following illustration shows a PDF document that contains
a unique identifier located in the document’s header.
For the purpose of this discussion, the unique page identifier
is placed in a document’s header. Assume that the following DDX
document is used.
<?xml version="1.0" encoding="UTF-8"?>
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDF result="out.pdf">
<Header>
<Center>
<StyledText>
<p font-size="20pt"><BatesNumber/></p>
</StyledText>
</Center>
</Header>
<PDF source="map.pdf" />
<PDF source="directions.pdf" />
</PDF>
</DDX>
This DDX document merges two PDF documents named
map.pdf
and
directions.pdf
into
a single PDF document. The resultant PDF document contains a header
that consists of a unique page identifier. For example, the document
in the above illustration shows 000016.
Before reading this section, it is recommended
that you be familiar with assembling PDF documents using the Assembler
service. This section does not discuss the concepts, such as creating
a collection object that contains input documents, or extracting
the results from the returned collection object. (See
Programmatically Assembling PDF Documents
.)
Summary of steps
To assemble a PDF document that contains a unique page
identifier (Bates numbering), perform the following tasks:
-
Include project files.
-
Create a PDF Assembler client.
-
Reference an existing DDX document.
-
Reference input PDF documents.
-
Set the initial Bates number value.
-
Assemble the input PDF documents.
-
Extract the results.
Include project files
Include 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 other than JBoss, you must replace
the adobe-utilities.jar and jbossall-client.jar files with JAR files
that are specific to the J2EE application server on which LiveCycle is deployed. For information about the location of all LiveCycle JAR files, see
Including LiveCycle Java library files
.
Create a PDF Assembler client
Before
you can programmatically perform an Assembler operation, you must
create an Assembler service client.
Reference an existing DDX document
A DDX document must be referenced
to assemble a PDF document. For example, consider the DDX document
that was introduced in this section. To assemble a PDF document
that contains unique page identifiers, the DDX document must contain
the
BatesNumber
element.
Reference input PDF documents
Input PDF documents must be referenced
to assemble a PDF document. For example, the map.pdf and directions.pdf
documents must be referenced to assemble these PDF documents into
a single PDF document.
Set the initial Bates number value
You can set the initial
Bates number value to meet your business requirements. For example,
assume that it is a requirement to set the initial value to 000100.
If you do not set the initial value, the value of the first page
is 000000.
Assemble the input PDF documents
After you create the Assembler
service client, reference the DDX document that contains
BatesNumber
element
information, reference an input PDF document, and set run-time options,
you can invoke the
invokeDDX
operation that results
in the Assembler service assembling a PDF document that contains
unique page identifiers.
Extract the results
The Assembler service returns a collection
object that contains the job results. You can extract the resultant
PDF document and any exceptions that are thrown. In this situation,
an encrypted PDF document is located within the collection object.
Note:
A collection object is returned if you invoke
the
invokeDDX
operation. This operation is used
when passing two or more input PDF documents to the Assembler service.
However if you pass only one input PDF document to the Assembler
service, you should invoke the
invokeOneDocument
operation.
For information about using this operation, see
Assembling Encrypted PDF Documents
.
Assemble documents with Bates numbering using the Java API
Assemble a PDF document that uses unique page identifiers
(Bates numbering) 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.
-
Create a PDF Assembler client.
-
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 input PDF documents.
-
Create a
java.util.Map
object used
to store input PDF documents by using a
HashMap
constructor.
-
For each input PDF document, create a
java.io.FileInputStream
object
by using its constructor and passing the location of the input PDF
document. In this situation, pass the location of an unsecured PDF
document.
-
For each input PDF document, create a
com.adobe.idp.Document
object
and pass the
java.io.FileInputStream
object that contains
the PDF document.
-
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. For example, the name of the PDF
source file specified in the DDX document that is introduced in
this section is Loan.pdf.
-
A
com.adobe.idp.Document
object that contains
the unsecured PDF document.
-
Set the initial Bates number value.
-
Create
an
AssemblerOptionSpec
object that stores run-time
options by using its constructor.
-
Set the initial Bates number by invoking the
AssemblerOptionSpec
object’s
setFirstBatesNumber
and
passing a numeric value that specifies the initial value.
-
Assemble the input PDF documents.
Invoke the
AssemblerServiceClient
object’s
invokeDDX
method
and pass the following required values:
-
A
com.adobe.idp.Document
object
that represents the DDX document.
-
A
java.util.Map
object that contains the
input unsecured PDF file.
-
A
com.adobe.livecycle.assembler.client.AssemblerOptionSpec
object
that specifies the run-time options, including default font and
job log level.
The
invokeDDX
method
returns a
com.adobe.livecycle.assembler.client.AssemblerResult
object
that contains a password-encrypted PDF document.
-
Extract the results.
To obtain the newly created PDF
document, perform the following actions:
-
Invoke the
AssemblerResult
object’s
getDocuments
method.
This action returns a
java.util.Map
object.
-
Iterate through the
java.util.Map
object
until you find the
com.adobe.idp.Document
object.
-
Invoke the
com.adobe.idp.Document
object’s
copyToFile
method
to extract the PDF document.
Assemble documents with Bates numbering using the web service API
Assemble a PDF document that uses unique page identifiers
(Bates numbering) 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:
http://localhost:8080/soap/services/AssemblerService?WSDL&lc_version=9.0.1
.
Note:
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 AEM forms 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
.

object by
invoking its constructor and passing a string value that represents the
file location of the DDX document and the mode to open the file in.
-
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.
Pass the byte array, the starting position, and the stream length
to read.
-
Populate the
BLOB
object by assigning its
MTOM
field
with the contents of the byte array.
-
Reference input PDF documents.
-
For each input
PDF document, create a
BLOB
object by using its
constructor. The
BLOB
object is used to store the
input PDF document.
-
Create a
System.IO.FileStream
object by
invoking its constructor. Pass a string value that represents the
file location of the input PDF 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.
Pass 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.
-
Create a
MyMapOf_xsd_string_To_xsd_anyType
object.
This collection object is used to store the input PDF documents.
-
For each input PDF document, create a
MyMapOf_xsd_string_To_xsd_anyType_Item
object.
For example, if two input PDF documents are used, create two
MyMapOf_xsd_string_To_xsd_anyType_Item
objects.
-
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. (Perform this task for each input PDF document.)
-
Assign the
BLOB
object that stores the PDF document
to the
MyMapOf_xsd_string_To_xsd_anyType_Item
object's
value
field.
(Perform this task for each input PDF document.)
-
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's
Add
method
and pass the
MyMapOf_xsd_string_To_xsd_anyType
object.
(Perform this task for each input PDF document.)
-
Set the initial Bates number value.
-
Create
an
AssemblerOptionSpec
object that stores run-time
options by using its constructor.
-
Set the initial Bates number by assigning a numeric value
to the
firstBatesNumber
data member that belongs
to the
AssemblerOptionSpec
object.
-
Assemble the input PDF documents.
Invoke the
AssemblerServiceClient
object’s
invoke
method
and pass the following values:
-
A
BLOB
object
that represents the DDX document.
-
The
MyMapOf_xsd_string_To_xsd_anyType
object
that contains the input PDF documents. Its keys must match the names
of the PDF source files, and its values must be the
BLOB
objects
that corresponds to those files.
-
An
AssemblerOptionSpec
object that specifies
run-time options.
The
invoke
method
returns an
AssemblerResult
object that contains
the results of the job and any exceptions that occurred.
-
Extract the results.
To obtain the newly created PDF
document, perform the following actions:
-
Access the
AssemblerResult
object’s
documents
field,
which is a
Map
object that contains the result
PDF documents.
-
Iterate through the
Map
object until you
find the key that matches the name of the 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.
