Rendering Rights-Enabled Forms rendering-rights-enabled-forms
The Forms service can render forms that have usage rights applied to them. 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. Forms that have usage rights applied to them are called rights-enabled forms. A user who opens a rights-enabled form in Adobe Reader can perform operations that are enabled for that form.
To apply usage rights to a form, the Acrobat Reader DC extensions service must be part of your AEM forms installation. Also, you must have a valid credential that enables you to apply usage rights to PDF documents. That is, you must properly configure the Acrobat Reader DC extensions service before you can render a rights-enabled form. (See About the Acrobat Reader DC extensions Service.)

To render a rights-enabled form, perform the following tasks:
- Include project files.
- Create a Forms Client API object.
- Set usage rights run-time options.
- Render a rights-enabled form.
- Write the rights-enabled form to the client web browser.
Include project files
Include necessary files into your development project. If you are creating a client application using Java, include the necessary JAR files. If you are using web services, ensure that you include the proxy files.
Create a Forms Client API object
Before you can programmatically perform a Forms service Client API operation, you must create a Forms service client.
Set usage rights run-time options
Set usage rights run-time options to render a rights-enabled form. Specify the alias of the credential that is used to apply usage rights to a form. After you specify the alias value, you specify each usage right to apply to the form.
Render a rights-enabled form
To render a rights-enabled form, you use the same application logic as rendering a form without usage rights. The only difference is that you must ensure that the usage rights run-time options are included in your application logic.
Write the form data stream to the client web browser
When the Forms service renders a rights-enabled form, it returns a form data stream that you must write to the client web browser. Once written to the client web browser, the form is visible to the user. A user viewing the rights-enabled form in Adobe Reader is able to perform operations that are enabled for that form.

Set usage rights run-time options
- Create a
ReaderExtensionSpecobject by using its constructor. - Specify the alias of the credential by invoking the
ReaderExtensionSpecobject’ssetReCredentialAliasmethod and specify a string value that represents the alias value. - Set each usage right by invoking the corresponding method that belongs to the
ReaderExtensionSpecobject. However, you can only set a usage right if the credential that you reference lets you do so. That is, you cannot set a usage right if the credential does not let you set it. For example. to set the usage right that enables a user to fill in form fields and save the form, invoke theReaderExtensionSpecobject’ssetReFillInmethod and passtrue.
note note NOTE It is not necessary to invoke the ReaderExtensionSpecobject’ssetReCredentialPasswordmethod. This method is not used by the Forms service. - Create a

Render a rights-enabled form
Invoke the
FormsServiceClientobject’srenderPDFFormWithUsageRightsmethod and pass the following values:- A string value that specifies the form design name, including the file name extension. If you reference a form design that is part of a Forms application, ensure that you specify the complete path, such as
Applications/FormsApplication/1.0/FormsFolder/Loan.xdp. - A
com.adobe.idp.Documentobject that contains data to merge with the form. If you do not want to merge data, pass an emptycom.adobe.idp.Documentobject. - A
PDFFormRenderSpecobject that stores run-time options. - A
ReaderExtensionSpecobject that stores usage rights run-time options. - A
URLSpecobject that contains URI values that are required by the Forms service.
The
renderPDFFormWithUsageRightsmethod returns aFormsResultobject that contains a form data stream that must be written to the client web browser. - A string value that specifies the form design name, including the file name extension. If you reference a form design that is part of a Forms application, ensure that you specify the complete path, such as
