You
can use the Output service to print streams such as PostScript,
Printer Control Language (PCL), or the following label formats to
a file:
Zebra - ZPL
Intermec - IPL
Datamax - DPL
TecToshiba - TPCL
Using the Output service, you can merge XML data with a form
design and print the form to a file. The following illustration
shows the Output service creating laser and label files.
Summary of stepsTo print
to a file, perform the following steps:
Include project files.
Create an Output Client object.
Reference an XML data source.
Set print run-time options required to print to a file.
Print the print stream to a file.
Retrieve the results of the operation.
Include project filesInclude 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,
make sure 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-output-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 that is not JBoss, you will need
to 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. (See Including LiveCycle Java library files.)
Create an Output Client objectBefore you can programmatically
perform an Output service operation, you must create an Output service
client object. If you are using the Java API, create an OutputClient object.
If you are using the Output web service API, create an OutputServiceService object.
Reference an XML data sourceTo print a document that contains data,
you must reference an XML data source that contains XML elements
for every form field that you want to populate with data. The XML
element name must match the field name. An XML element is ignored
if it does not correspond to a form field or if the XML element
name does not match the field name. It is not necessary to match
the order in which the XML elements are displayed if all XML elements
are specified.
Set print run-time options required to print to a fileTo
print to a file, you must set the File URI run-time option by specifying
the location and the name of the file to which the Output service
prints. For example, to instruct the Output service to print a PostScript
file named MortgageForm.ps to C:\Adobe, specify C:\Adobe\MortgageForm.ps.
注意： There are optional run-time options that you can
define. For information about all the options that you can set,
see the PrintedOutputOptionsSpec class reference
in LiveCycle API Reference.
Print the print stream to a fileAfter you reference a valid
XML data source that contains form data and you set print run-time
options, you can invoke the Output service, which causes it to print
a file.
Retrieve the results of the operationAfter the Output service
performs an operation, it returns various data items, such as XML
data, that specifies whether the operation was successful.
Print to files using the Java APIPrint to a file using the Output API (Java):
Include project files.
Include client JAR files,
such as the adobe-output-client.jar, in your Java project’s class
path.
Create an Output Client object.
Reference an XML data source.
Create a java.io.FileInputStream object
that represents the XML data source that is used to populate the
document by using its constructor and passing a string value that
specifies the location of the XML file.
Create a com.adobe.idp.Document object by
using its constructor and passing the java.io.FileInputStream object.
Set print run-time options required to print to a file.
Create a PrintedOutputOptionsSpec object
by using its constructor.
Specify the file by invoking the PrintedOutputOptionsSpec object’s setFileURI method
and passing a string value that represents the name and location
of the file. For example, if you want the Output service to print
to a PostScript file named MortgageForm.ps located in C:\Adobe,
specify C:\\Adobe\MortgageForm.ps.
Specify the number of copies to print by invoking the PrintedOutputOptionsSpec object’s setCopies method
and passing an integer value that represents the number of copies.
Print the print stream to a file.
Print to a file
by invoking the OutputClient object’s generatePrintedOutput method
and passing the following values:
A PrintFormat enumeration
value that specifies the print stream format to create. For example,
to create a PostScript print stream, pass PrintFormat.PostScript.
A string value that specifies the name of the form design.
A string value that specifies the location of related collateral
files such as image files.
A string value that specifies the location of the XDC file
to use (you can pass null if you specified the
XDC file to use by using the PrintedOutputOptionsSpec object).
The PrintedOutputOptionsSpec object that
contains run-time options required to print to a file.
The com.adobe.idp.Document object that contain
the XML data source that contains form data.
The generatePrintedOutput method
returns an OutputResult object that contains the
results of the operation.
注意： The OutputResult object’s getRecordLevelMetaDataList method
returns null.
Retrieve the results of the operation.
Create
a com.adobe.idp.Document object that represents
the status of the generatePrintedOutput method
by invoking the OutputResult object’s getStatusDoc method
(the OutputResult object was returned by the generatePrintedOutput method).
Create a java.io.File object that will contain
the results of the operation. Ensure that the file extension is
XML.
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 getStatusDoc method).
Print to files using the web service APIPrint to a file using the Output 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/OutputService?WSDL&lc_version=9.0.1.
注意： Replace localhost with the IP address of the server hosting LiveCycle.
Create an Output Client object.
Create an OutputServiceClient object
by using its default constructor.
Create an OutputServiceClient.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/OutputService?blob=mtom.)
You do not need to use the lc_version attribute.
This attribute is used when you create a service reference. However,
specify ?blob=mtom to use MTOM.
Create a System.ServiceModel.BasicHttpBinding object
by getting the value of the OutputServiceClient.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 OutputServiceClient.ClientCredentials.UserName.UserName.
Assign the corresponding password value to the field OutputServiceClient.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.
Reference an XML data source.
Create a BLOB object
by using its constructor. The BLOB object is used
to store form data.
Create a System.IO.FileStream object by
invoking its constructor and passing a string value that specifies the
location of the XML file that contains form data.
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
and passing the byte array, the starting position, and the stream
length to read.
Populate the BLOB object by assigning its binaryData property
with the contents of the byte array.
Set print run-time options required to print to a file.
Create a PrintedOutputOptionsSpec object
by using its constructor.
Specify the file by assigning a string value that represents
the location and name of the file to the PrintedOutputOptionsSpec object’s fileURI data
member. For example, if you want the Output service to print to
a PostScript file named MortgageForm.ps located in C:\Adobe,
specify C:\\Adobe\MortgageForm.ps.
Specify the number of copies to print by assigning an integer value
that represents the number of copies to the PrintedOutputOptionsSpec object’s copies data
members.
Print the print stream to a file.
Print to a file
by invoking the OutputServiceService object’s generatePrintedOutput method
and passing the following values:
A PrintFormat enumeration
value that specifies the print stream format to create. For example,
to create a PostScript print stream, pass PrintFormat.PostScript.
A string value that specifies the name of the form design.
A string value that specifies the location of related collateral
files such as image files.
A string value that specifies the location of the XDC file
to use (you can pass null if you specified the
XDC file to use by using the PrintedOutputOptionsSpec object).
The PrintedOutputOptionsSpec object that
contains print run-time options required to print to a file.
The BLOB object that contains the XML data source
that contains form data.
A BLOB object that is populated by the generatePDFOutput method.
The generatePDFOutput method populates this object
with generated metadata that describes the document. (This parameter
value is required for web service invocation only.)
A BLOB object that is populated by the generatePDFOutput method.
The generatePDFOutput method populates this object
with result data. (This parameter value is required for web service invocation
only.)
An OutputResult object that contains the
results of the operation. (This parameter value is required for
web service invocation only.)
Retrieve the results of the operation.
Create
a System.IO.FileStream object by invoking its constructor
and passing a string value that represents an XML file location
that contains result data. Ensure that the file extension is XML.
Create a byte array that stores the data content of the BLOB object
that was populated with result data by the OutputServiceService object’s generatePDFOutput method
(the eighth parameter). 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 the XML file by invoking
the System.IO.BinaryWriter object’s Write method
and passing the byte array.
