Assigning Usage Rights

About the Acrobat Reader DC extensions Service

The Acrobat Reader DC extensions service enables your organization to easily share interactive PDF documents by extending the functionality of Adobe Reader. The Acrobat Reader DC 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 Acrobat Reader DC extensions service:
For more information about the Acrobat Reader DC extensions service, see Services Reference for AEM Forms .

Applying Usage Rights to PDF Documents

You can apply usage rights to PDF documents using the Acrobat Reader DC 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.
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 steps

To apply usage rights to a PDF document, perform the following steps:
  1. Include project files.
  2. Create a Acrobat Reader DC extensions Client object.
  3. Retrieve a PDF document.
  4. Specify usage rights to apply.
  5. Apply usage rights to the PDF document.
  6. Save the rights-enabled PDF document.
Include project files
Include 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 Acrobat Reader DC extensions Client object
To programmatically perform a Acrobat Reader DC extensionsservice operation, you must create a Acrobat Reader DC extensions service client object. If you are using the Acrobat Reader DC extensions Java API, create a ReaderExtensionsServiceClient object. If you are using the Acrobat Reader DC extensions web service API, create a ReaderExtensionsServiceService object.
Retrieve a PDF document
You 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 Acrobat Reader DC extensions service creates one. If it already contains a dictionary, the Acrobat Reader DC 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 apply
The 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.
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 document
To 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 AEM Forms). 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 document
After the Acrobat Reader DC 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 API

Apply usage rights to a PDF document by using the Acrobat Reader DC Extensions API (Java):
  1. Include project files
    Include client JAR files, such as adobe-reader-extensions-client.jar, in your Java project’s class path.
  2. Create a Acrobat Reader DC extensions Client object.
    • Create a ServiceClientFactory object that contains connection properties.
    • Create a ReaderExtensionsServiceClient object by using its constructor and passing the ServiceClientFactory object.
  3. 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.
  4. 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).
  5. 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 Acrobat Reader DC 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.
  6. 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 API

Apply usage rights to a PDF document by using the Acrobat Reader DC Extensions API (web service):
  1. 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 .
    Replace localhost with the IP address of the server hosting AEM Forms.
  2. Create a Acrobat Reader DC extensions Client object.
    • Create a ReaderExtensionsServiceClient object by using its default constructor.
    • Create a ReaderExtensionsServiceClient.Endpoint.Address object by using the System.ServiceModel.EndpointAddress constructor. Pass a string value that specifies the WSDL to the AEM Forms service (for example, http://localhost:8080/soap/services/ReaderExtensionsService?blob=mtom . 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 AEM forms 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 .
  3. 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.
  4. 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).
  5. 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 Acrobat Reader DC 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:

      • 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.
  6. 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 Documents

You 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 AEM Forms 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.
For more information about the Acrobat Reader DC extensions service, see Services Reference for AEM Forms .
