The LiveCycle Forms service renders interactive
PDF forms to client devices, typically web browsers, to collect
information from users. An interactive PDF form is based on a form
design that is typically saved as an XDP file and created in Designer.
As of LiveCycle, you can pass a com.adobe.idp.Document object
that contains the form design to the Forms service. The Forms service
then renders the form design located in the com.adobe.idp.Document object.
An advantage of passing a com.adobe.idp.Document object
to the Forms service is that other service operations return a com.adobe.idp.Document instance.
That is, you can get a com.adobe.idp.Document instance
from another service operation and render it. For example, assume
that an XDP file is stored in a Content Services (deprecated) node
named /Company Home/Form Designs, as shown in the
following illustration.
You can programmatically retrieve Loan.xdp from Content Services (deprecated)
(deprecated) and pass the XDP file to the Forms service within a com.adobe.idp.Document object.
Summary of stepsTo pass a document obtained from Content Services (deprecated)
(deprecated) to the Forms service, perform the following tasks:
Include project files.
Create a Forms and a Document Management Client API object.
Retrieve the form design from Content Services (deprecated).
Render the interactive PDF form.
Perform an action with the form data stream.
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,
include the proxy files.
Create a Forms and a Document Management Client API objectBefore
you can programmatically perform a Forms service API operation, create
a Forms Client API object. Also, because this workflow retrieves
an XDP file from Content Services (deprecated), create a Document
Management API object.
Retrieve the form design from Content Services (deprecated)Retrieve
the XDP file from Content Services (deprecated) by using the Java or
web service API. The XDP file is returned within a com.adobe.idp.Document instance
(or a BLOB instance if you are using web services).
You can then pass the com.adobe.idp.Document instance
to the Forms service.
Render an interactive PDF formTo
render an interactive form, pass the com.adobe.idp.Document instance
that was returned from Content Services (deprecated) to the Forms
service.
Hinweis: You can pass a com.adobe.idp.Document that
contains the form design to the Forms service. Two new methods named renderPDFForm2 and renderHTMLForm2 accept
a com.adobe.idp.Document object that contains a
form design.
Perform an action with the form data streamDepending on the type
of client application, you can write the form to a client web browser
or save the form as a PDF file. A web-based application typically
writes the form to web browser. However, a desktop application typically
saves the form as a PDF file.
Pass documents to the Forms Service using the Java APIPass a document obtained from Content Services (deprecated)
by using the Forms service and Content Services (deprecated) API
(Java):
Include project files
Include client JAR files,
such as adobe-forms-client.jar and adobe-contentservices-client.jar,
in your Java project’s class path.
Create a Forms and a Document Management Client API object
Create a ServiceClientFactory object that
contains connection properties. (See Setting connection properties.)
Create an FormsServiceClient object by using
its constructor and passing the ServiceClientFactory object.
Create a DocumentManagementServiceClientImpl object
by using its constructor and passing the ServiceClientFactory object.
Retrieve the form design from Content Services (deprecated)
Invoke
the DocumentManagementServiceClientImpl object’s retrieveContent method
and pass the following values:
A string value that
specifies the store where the content is added. The default store
is SpacesStore. This value is a mandatory parameter.
A string value that specifies the fully qualified path of
the content to retrieve (for example, /Company Home/Form Designs/Loan.xdp).
This value is a mandatory parameter.
A string value that specifies the version. This value is
an optional parameter, and you can pass an empty string. In this
situation, the latest version is retrieved.
The retrieveContent method
returns a CRCResult object that contains the XDP
file. Obtain a com.adobe.idp.Document instance
by invoking the CRCResult object’s getDocument method.
Render an interactive PDF form
Invoke the FormsServiceClient object’s renderPDFForm2 method
and pass the following values:
A com.adobe.idp.Document object
that contains the form design retrieved from Content Services (deprecated).
A com.adobe.idp.Document object that contains
data to merge with the form. If you do not want to merge data, pass
an empty com.adobe.idp.Document object.
A PDFFormRenderSpec object that stores run-time
options. This value is an optional parameter, and you can specify null if
you do not want to specify run-time options.
A URLSpec object that contains URI values. This
value is an optional parameter, and you can specify null.
A java.util.HashMap object that stores file
attachments. This value is an optional parameter, and you can specify null if
you do not want to attach files to the form.
The renderPDFForm method
returns a FormsResult object that contains a form
data stream that must be written to the client web browser.
Perform an action with the form data stream
Create a com.adobe.idp.Document object by
invoking the FormsResult object ‘s getOutputContent method.
Get the content type of the com.adobe.idp.Document object
by invoking its getContentType method.
Set the javax.servlet.http.HttpServletResponse object’s
content type by invoking its setContentType method
and passing the content type of the com.adobe.idp.Document object.
Create a javax.servlet.ServletOutputStream object
used to write the form data stream to the client web browser by invoking
the javax.servlet.http.HttpServletResponse object’s getOutputStream method.
Create a java.io.InputStream object by invoking
the com.adobe.idp.Document object’s getInputStream method.
Create a byte array and populate it with the form data stream
by invoking the InputStream object’s read method.
Pass the byte array as an argument.
Invoke the javax.servlet.ServletOutputStream object’s write method
to send the form data stream to the client web browser. Pass the
byte array to the write method.
Pass documents to the Forms Service using the web service APIPass a document obtained from Content Services (deprecated)
by using the Forms service and Content Services (deprecated) API
(web service):
Include project files
Create a Microsoft .NET
project that uses MTOM. Because this client application invokes
two LiveCycle services, create two service references. Use
the following WSDL definition for the service reference associated
with the Forms service: http://localhost:8080/soap/services/FormsService?WSDL&lc_version=9.0.1.
Use
the following WSDL definition for the service reference associated with
the Document Management service: http://localhost:8080/soap/services/DocumentManagementService?WSDL&lc_version=9.0.1.
Because
the BLOB data type is common to both service references,
fully qualify the BLOB data type when using it.
In the corresponding web service quick start, all BLOB instances
are fully qualified.
Hinweis: Replace localhost with the IP address of the server hosting LiveCycle.
Create a Forms and a Document Management Client API object
Create a FormsServiceClient object by using
its default constructor.
Create a FormsServiceClient.Endpoint.Address object
by using the System.ServiceModel.EndpointAddress constructor.
Pass a string value that specifies the WSDL to the LiveCycle Forms service (for example, http://localhost:8080/soap/services/FormsService?WSDL).
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 FormsServiceClient.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 FormsServiceClient.ClientCredentials.UserName.UserName.
Assign the corresponding password value to the field FormsServiceClient.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.
Hinweis: Repeat these steps for the DocumentManagementServiceClient service client.
Retrieve the form design from Content Services (deprecated)
Retrieve
content by invoking the DocumentManagementServiceClient object’s retrieveContent method
and passing the following values:
A string value that
specifies the store where the content is added. The default store
is SpacesStore. This value is a mandatory parameter.
A string value that specifies the fully qualified path of
the content to retrieve (for example, /Company Home/Form Designs/Loan.xdp).
This value is a mandatory parameter.
A string value that specifies the version. This value is
an optional parameter, and you can pass an empty string. In this
situation, the latest version is retrieved.
A string output parameter that stores the browse link value.
A BLOB output parameter that stores the content.
You can use this output parameter to retrieve the content.
A ServiceReference1.MyMapOf_xsd_string_To_xsd_anyType output
parameter that stores content attributes.
A CRCResult output parameter. Instead of using
this object, you can use the BLOB output parameter
to obtain the content.
Render an interactive PDF form
Invoke the FormsServiceClient object’s renderPDFForm2 method
and pass the following values:
A BLOB object
that contains the form design retrieved from Content Services (deprecated).
A BLOB object that contains data to merge with
the form. If you do not want to merge data, pass an empty BLOB object.
A PDFFormRenderSpec object that stores run-time
options. This value is an optional parameter, and you can specify null if
you do not want to specify run-time options.
A URLSpec object that contains URI values. This
value is an optional parameter, and you can specify null.
A Map object that stores file attachments. This
value is an optional parameter, and you can specify null if
you do not want to attach files to the form.
A long output parameter that is used to store the page count.
A string output parameter that is used to store the locale
value.
A FormsResult output parameter that is used
to store the interactrive PDF form.
The renderPDFForm2 method
returns a FormsResult object that contains the
interactive PDF form.
Perform an action with the form data stream
Create a BLOB object that contains form
data by getting the value of the FormsResult object’s outputContent field.
Create a System.IO.FileStream object by
invoking its constructor. Pass a string value that represents the
file location of the interactive PDF document and the mode in which
to open the file.
Create a byte array that stores the content of the BLOB object
retrieved from the FormsResult object. 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.
