About the Reader Extensions ServiceThe
Reader Extensions service enables your organization to easily share
interactive PDF documents by extending the functionality of Adobe
Reader. The Reader Extensions service fully supports any PDF document,
up to and including PDF 1.7. It works with Adobe Reader 7.0 and later.
The service adds usage rights to a PDF document, activating features
that are not usually available when a PDF document is opened using
Adobe Reader. Third party users do not require additional software
or plug-ins to work with the rights-enabled documents.
You can accomplish these tasks using the Reader Extensions service:
Applying Usage Rights to PDF DocumentsYou
can apply usage rights to PDF documents using the Reader Extensions
Java Client API and web service. Usage rights pertain to functionality
that is available by default in Acrobat but not in Adobe Reader,
such as the ability to add comments to a form or to fill in form
fields and save the form. PDF documents that have usage rights applied
to them are called rights-enabled documents. A user who opens a rights-enabled
document in Adobe Reader can perform operations that are enabled
for that specific document.
注意： When applying usage rights to PDF documents
using the applyUsageRights method, which is part
of the Java API, you can set the isModeFinal parameter
of the ReaderExtensionsOptionSpec object to false.
This results in the forms processed counter not being updated and
an improvement in performance. If you are not concerned about updating
the forms processed counter, it is recommended that you set the isModeFinal parameter
to false.
Summary of stepsTo apply usage rights to a PDF document,
perform the following steps:
Include project files.
Create a Reader Extensions Client object.
Retrieve a PDF document.
Specify usage rights to apply.
Apply usage rights to the PDF document.
Save the rights-enabled PDF document.
Include project filesInclude necessary files into your development
project. If you are creating a client application using Java, then
include the necessary JAR files. If you are using web services,
then make sure that you include the proxy files.
Create a Reader Extensions Client objectTo programmatically
perform a Reader Extensionsservice operation, you must create a
Reader Extensions service client object. If you are using the Reader Extensions
Java API, create a ReaderExtensionsServiceClient object.
If you are using the Reader Extensions web service API, create a ReaderExtensionsServiceService object.
Retrieve a PDF documentYou must retrieve a PDF document in order
to apply usage rights. Rights-enabled PDF documents contain a usage
rights dictionary. When Adobe Reader opens a document containing
such a dictionary, it enables the usage rights specified in the
dictionary for that document only. If the document does not contain
a usage rights dictionary, the Reader Extensions service creates
one. If it already contains a dictionary, the Reader Extensions
service overwrites existing usage rights with the ones you specify.
The dictionary specifies which usage rights are enabled. When a
user opens the document in Adobe Reader, only the usage rights specified
in the dictionary are permitted.
Specify usage rights to applyThe usage rights that you can set
are determined by a credential that you purchase from Adobe Systems
Incorporated. Credentials typically provide permission to set a
group of related usage rights, such as those pertaining to interactive
forms. Each credential provides the right to create a certain number of
rights-enabled PDF documents. An evaluation credential gives the
right to create an unlimited number of draft documents.
注意： If you attempt to assign a usage right that is
not permitted by your credential, you will cause an exception.
Apply usage rights to the PDF documentTo apply usage rights
to a PDF document, you reference the alias of the credential that
you are using to apply usage rights (a credential is typically installed
during the installation of LiveCycle). Also you must specify
the PDF document to which usage rights is applied. For information
abut configuring a credential, see the installing and deploying
guide for your application server.
Save the rights-enabled PDF documentAfter the Reader Extensions
service applies usage rights to a PDF document, you can save the
rights-enabled PDF document as a PDF file.
Apply usage rights using the Java APIApply usage rights to a PDF document by using the Reader
Extensions API (Java):
Include project files
Include client JAR files,
such as adobe-reader-extensions-client.jar, in your Java project’s
class path.
Create a Reader Extensions Client object.
Retrieve a PDF document.
Create a java.io.FileInputStream object
that represents the PDF document by using its constructor and passing
a string value that specifies the location of the PDF document.
Create a com.adobe.idp.Document object by
using its constructor and passing the java.io.FileInputStream object.
Specify usage rights to apply.
Create a UsageRights object
that represents usage rights by using its constructor.
For each usage right to apply, invoke a corresponding method that
belongs to the UsageRights object. For example,
to add the enableFormFillIn usage right, invoke
the UsageRights object’s enableFormFillIn method
and pass true. (Repeat this step for each usage
right to apply).
Apply usage rights to the PDF document.
Create
a ReaderExtensionsOptionSpec object by using its
constructor. This object contains run-time options that are required
by the Reader Extensions service. When invoking this constructor,
you must specify the following values:
The UsageRights object
that contains the usage rights to apply to the document.
A string value that specifies a message that a user sees
when the rights-enabled PDF document is opened in Adobe Reader 7.x.
This message is not displayed in Adobe Reader 8.0.
Apply usage rights to the PDF document by invoking the ReaderExtensionsServiceClient object’s applyUsageRights method
and passing the following values:
The com.adobe.idp.Document object
that contains the PDF document to which usage rights is applied.
A string value that specifies the alias of the credential
that enables you to apply usage rights.
A string value that specifies the corresponding password
value. (Currently this parameter is ignored. You can pass null.)
The ReaderExtensionsOptionSpec object that
contains run-time options.
The applyUsageRights method
returns a com.adobe.idp.Document object that contains
the rights-enabled PDF document.
Save the rights-enabled PDF document.
Create
a java.io.File object and ensure that the file
extension is .pdf.
Invoke the com.adobe.idp.Document object’s copyToFile method
to copy the contents of the com.adobe.idp.Document object
to the file (ensure that you use the com.adobe.idp.Document object
that was returned by the applyUsageRights method).
Apply usage rights using the web service APIApply usage rights to a PDF document by using the Reader
Extensions 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/ReaderExtensionsService?WSDL&lc_version=9.0.1.

Ensure you specify ?blob=mtom.)
Create a System.ServiceModel.BasicHttpBinding object
by getting the value of the ReaderExtensionsServiceClient.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 ReaderExtensionsServiceClient.ClientCredentials.UserName.UserName.
Assign the corresponding password value to the field ReaderExtensionsServiceClient.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.
Retrieve a PDF document.
Create a BLOB object
by using its constructor. The BLOB object is used
to store a PDF document to which a usage rights is applied.
Create a System.IO.FileStream object by
invoking its constructor and passing a string value that represents the
file location of the 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.
Specify usage rights to apply.
Create a UsageRights object
that represents usage rights by using its constructor.
For each usage right to apply, assign the value true to
the corresponding data member that belongs to the UsageRights object.
For example, to add the enableFormFillIn usage
right, assign true to the UsageRights object’s enableFormFillIn data
member. (Repeat this step for each usage right to apply).
Apply usage rights to the PDF document.
Create
a ReaderExtensionsOptionSpec object by using its
constructor. This object contains run-time options that are required
by the Reader Extensions service.
Assign the UsageRights object to the ReaderExtensionsOptionSpec object’s usageRights data
member.
Assign a string value that specifies the message that a user
sees when the rights-enabled PDF document is opened in Adobe Reader
to the ReaderExtensionsOptionSpec object’s message data
member.
Apply usage rights to the PDF document by invoking the ReaderExtensionsServiceClient object’s applyUsageRights method
and passing the following values:
The BLOB object
that contains the PDF document to which usage rights is applied.
A string value that specifies the alias of the credential
that enables you to apply usage rights.
A string value that specifies the corresponding password
value. (Currently this parameter is ignored. You can pass null.)
The ReaderExtensionsOptionSpec object that
contains run-time options.
The applyUsageRights method
returns a BLOB object that contains the rights-enabled
PDF document.
Save the rights-enabled PDF document.
Create
a System.IO.FileStream object by invoking its constructor.
Pass a string value that represents the file location of the rights-enabled
PDF document.
Create a byte array that stores the data content of the BLOB object
that was returned by the applyUsageRights method.
Populate the byte array by getting the value of the BLOB object’s MTOM data
member.
Create a System.IO.BinaryWriter object by
invoking its constructor and passing the System.IO.FileStream object.
Write the contents of the byte array to a PDF file by invoking
the System.IO.BinaryWriter object’s Write method
and passing the byte array.
Removing Usage Rights from PDF DocumentsYou can remove usage rights from
a rights-enabled document. Removing usage-rights from a rights-enabled PDF
document is also necessary in order to perform other LiveCycle operations
on it. For example, you must digitally sign (or certify) a PDF document before
you set usage rights. Therefore if you want to perform operations
on a rights-enabled document, you must remove usage rights from
the PDF document, perform the other operations, such as digitally
signing the document, and then re-apply usage rights to the document.
Summary of stepsTo remove usage rights from
a rights-enabled PDF document, perform the following steps:
Include project files.
Create a Reader Extensions Client object.
Retrieve a rights-enabled PDF document.
Remove usage rights from the PDF document.
